Q&A with Jason Bock: Visual Studio 2019 Features You Need to Know About

We caught up with Jason Bock, a practice lead for Magenic (http://www.magenic.com) and a Microsoft MVP (C#) with more than 20 years of experience working on business applications using a diverse set of frameworks and languages including C#, .NET, and JavaScript.

Bock, the author of ".NET Development Using the Compiler API," "Metaprogramming in .NET," and "Applied .NET Attributes, is leading the full-day “Visual Studio 2019 In-depth” workshop at the upcoming “Visual Studio Live!” conference set for March 30 - April 3 in Austin, Texas.

The workshop begins with the premise that the capabilities and features within Visual Studio are vast, so much so that users may not be aware of everything that Visual Studio has to offer. In the full-day session, Bock will give a fast-paced tour of the Visual Studio landscape, including configuration, debugging, code analysis, unit testing, performance, metrics and more. Attendees will also find out about new features that are in Visual Studio 2019. By the end of this session, developers will have a solid understanding of Visual Studio so they can quickly develop reliable, maintainable solutions including:

  • Understanding the vast Visual Studio ecosystem
  • Gaining insights into Visual Studio analysis tools to improve applications
  • Finding out how to extend Visual Studio with extensions and templates

Ahead of the workshop, we asked Bock about Visual Studio 2019 and he even shared his favorite little known feature with us.

Question: You have a full-day workshop deep-diving into Visual Studio 2019, so hopefully this isn’t too much of a spoiler, but what is your number #1 feature in VS2019 that you’re surprised more developers don’t know about?

Answer: There are a lot of features in Visual Studio, so even if you’ve used it for years, there’s always something new to find. One addition was the support of .editorconfig files, which defines the formatting styles for a project. If you have that file with a solution, VS will automatically honor those settings, so you no longer have to ensure VS is configured to match the formatting expectations.

Q: What do you think is the most powerful aspect of VS 2019 compared to other versions?
A: There are always new features added to VS, but to me, the biggest change for VS is the frequency of updates and revisions. In the old days, updates to VS were infrequent, service packs could completely invalidate an installation, and using preview versions could only be done within a virtual machine. You just couldn’t trust updates or preview versions. Now, with VS 2017 and 2019, the installation process is much cleaner, and preview versions are truly separated from the “main” version. It’s not perfect, but it’s a big improvement from the way things were.

Q: What is your personal favorite little-known or unknown feature?
A: C# Interactive. You can see that you can use C# as a scripting language within VS. It’s somewhat bare-bones in terms of the features it has, but it’s nice if you want to try out some C# code within VS outside of a solution.

Q: What are your go-to Visual Studio tools?
A: I’m not a developer that uses a lot of tools in terms of extensions. I pretty much stick to what’s in VS, which turns out, there’s more there than people realize. The things I watch out for are new refactorings and key bindings with new versions of VS to enhance the coding experience.

Q: If we let you have one more extension, what would it be?
A: This may be surprising to some developers, but I stick to the tools that come with VS, and that typically is more than enough for what I do. I know there are some extensions that .NET developers insist you must use, but knowing what VS has out of the box, especially with recent versions, can be somewhat of an eye-opening experience.

Q: Anything else that we haven’t asked you that you wish we had?
A: The one thing I’d like to encourage developers is to get familiar with the key bindings and shortcuts within VS. The more you can keep your hands off the mouse, the faster you’ll be. Using Quick Help (Ctrl + Q) to discover features in VS along with any associated key bindings.

Discovering Cosmos: The Database for the Global Economy

Microsoft’s Cosmos isn’t a new database. It’s been around since 2010. But when coupled with Azure, its globally-distributed database in the cloud model seems ideal for business app developers in 2020.

“Cosmos DB enables you to build highly responsive and highly available applications worldwide,” touts Microsoft in its introduction to its NoSQL database. “Cosmos DB transparently replicates your data wherever your users are, so your users can interact with a replica of the data that is closest to them.”

The proximity of data to users is important because speed thrills when it comes to building business apps in the global mobile world. Users expect to see the information they need in a blink of an eye and that’s what Azure Cosmos provides.

“You can elastically scale throughput and storage, and take advantage of fast, single-digit-millisecond data access using your favorite API including SQL, MongoDB, Cassandra, Tables, or Gremlin,” Microsoft explains.

The elastic scalability of Azure Cosmos provides the flexibility business apps need where market demands can go up and down within hours, minutes or even seconds. “You can elastically scale up from thousands to hundreds of millions of requests/sec around the globe, with a single API call and pay only for the throughput (and storage) you need,” according to Microsoft. “This capability helps you to deal with unexpected spikes in your workloads without having to over-provision for the peak.”

Retail and Marketing
Applications that can handle the peaks and valleys of the retail industry are among the use cases that Microsoft highlights for Azure Cosmos. Here the company eats its own dog food: “Azure Cosmos DB is used extensively in Microsoft's own e-commerce platforms that run the Windows Store and XBox Live.”

Beyond its own applications, Microsoft says Cosmos is designed to handle online retail functions such as storing catalog data and event sourcing in order processing pipelines:

“Catalog data usage scenarios involve storing and querying a set of attributes for entities such as people, places, and products. Some examples of catalog data are user accounts, product catalogs, IoT device registries, and bill of materials systems. Attributes for this data may vary and can change over time to fit application requirements. “Consider an example of a product catalog for an automotive parts supplier. Every part may have its own attributes in addition to the common attributes that all parts share. Furthermore, attributes for a specific part can change the following year when a new model is released. Azure Cosmos DB supports flexible schemas and hierarchical data, and thus it is well suited for storing product catalog data.”

Cosmos Case Study
Microsoft backs up its claims for Azure Cosmos with case studies of the database in action from a number of prestigious customers.

One Microsoft customer story highlights how FUJIFILM employed Azure Cosmos database speed to enhance their customers’ experience. The Japanese company, which has transitioned from the photographic film business to become a leader in digital photography, wanted to improve digital photo management and file sharing for users of its IMAGE WORKS service. Photographers are typically anxious to see and share their work as instantly as possible. Using Azure Cosmos DB for its image file database, FUJIFILM was able to provide users with higher responsiveness and lower latency from IMAGE WORKS. Microsoft noted that response time for end users accelerated by a factor of 10 while some photographer interactions accelerated by 20 times and more over the previous database. With Azure Cosmos, a tree view photo display in image search processing, which included 140 tables and 1,000 rows of SQL queries, went from 45 seconds, which would seem like an eternity to impatient shutterbugs, to two seconds. “The more responsive we can make IMAGE WORKS, the more productive our customers can be,” said Yuki Chiba, Design Leader of the Advanced Solutions Group IMAGE WORKS Team at FUJIFILM Software.

Deep Dive on Cosmos DB
If you want to go beyond reading about it and really explore the Cosmos, Visual Studio Live! coming to Austin, TX March 30 through April 3 offers a full afternoon Deep Dive on Cosmos DB. Leonard Lobel, Microsoft MVP and CTO at Sleek Technologies, Inc., will lead developers on a journey through the Cosmos DB starting with an introduction including its multi-model capabilities which allow you to store and query schema-free JSON documents (using either SQL or MongoDB APIs), graphs (Gremlin API), and key/value entities (table API).

Diving deeper, in Part II, “Building Cosmos DB Applications,” you'll learn how to write apps for Cosmos DB, and see how to work with the various Cosmos DB APIs. These APIs support a variety of data models, including the SQL API (for JSON documents), Table API for (key-value entities), Gremlin API (for graphs) and Cassandra (for columnar). Regardless what you choose as a data model of choice, you'll learn how to provision throughput, and how to partition and globally distribute your data to deliver massive scale. You’ll come away knowing how to:

  • Write code to build Cosmos DB applications
  • Use the Cosmos DB server-side programming model to run stored procedures, triggers, and user-defined functions and explore the special version of SQL designed for querying Cosmos DB
  • Use the Cosmos DB server-side programming model to run stored procedures, triggers, and user-defined functions

Is it SAFe? Or is it Scrum?

What's SAFe? Are you doing Scrum? This might sound like dialogue outtakes from an old movie. But it is actually about alternative approaches to application development.

Scrum is sometimes shown in all caps as SCRUM but it is not an acronym. SAFe on the other hand stands for Scaled Agile Framework. Both have official websites: https://www.scrum.org/ and https://www.scaledagileframework.com/.

Both are approaches to Agile development. In the case of SAFe, Agile is its middle name. This whole thing started earlier in the decade when a group of developers published The Manifesto for Agile Software Development. The idea was to get away from older and cumbersome coding practices, which despite everybody's best intentions for detailed planning often started with little more than a manager saying: "I need you guys to write a program that [fill in the blank].

Because of heroic efforts by developers, that method usually worked, otherwise we would have had no applications to run since the personal computer revolution. And there was the Waterfall Method that organized development into steps starting with writing requirements (what a concept!) for the planned application. Then it went to phases of design, coding, QA, production and maintenance. Often those phases were handled by different teams with limited interaction or feedback. It worked more or less like an automobile assembly line. But it was rarely a collaborative process.

Agile is a collaborative process starting with a new emphasis on:

  • Individuals and interactions over processes and tools
  • Working software over comprehensive documentation
  • Customer collaboration over contract negotiation
  • Responding to change over following a plan

There are 12 guiding principles to Agile that you can read about here. This is great but it's what MBA types call high level. You can see the whole battlefield from 10,000 feet. But what's going on in the trenches? On a day-to-day basis when you are trying to produce an app, what is everybody supposed to be doing? That's where SAFe and Scrum comes into play. They are essentially ways to actually do Agile development. They take different approaches, so you might ask: "What's the difference between SAFe and Scrum?"

Krishna Ramalingam gives basic answers to that question in a seven-minute YouTube video:

"Bottom line both are offshoots of Agile principles," he tells his audience. "Both talk about releasing in short iterations. The fundamental difference with SAFe is Scaled Agile Framework. Scrum focused on a smaller project unit and provides the framework on how this has to be handled."

With Scrum a team is working in iterations called sprints, Ramalingam explains. He uses the example of 10 teams working on 10 projects that will eventually come together as one product.

"All the 10 projects start and stop the sprint at the same time," he explains. "This way planning dependencies become easier and it also gives a view of what each of the teams can implement so as to deliver a bigger meaningful feature for the product level. So you align all the teams and you start sprinting."

A sprint might be three weeks and after that there would be a one week "hardening sprint" where the teams address issues that come up in the review. The advantage of this approach is that all the team members have an idea of what is going on with the other projects. It helps avoid that dreadful question: "Why did you do that?" With this kind of coordinated effort, ideally the 10 projects come together in one app.

"At the end of this you do a complete product level demo and promote the code to the production server and make a formal product release," Ramalingam explains.

But Scrum leaves some of the nitty gritty parts of the project up to the team members to figure out on their own, he adds. This is where SAFe offers more guidance. It covers things like "how budgeting should be done, the strategy and the governance under which the agile release trains are executed," he says. It offers more guidance on how 10 projects and be coordinated so they become one final application. Ramalingam sees this as something best suited for larger organizations.

"Should you follow Scrum or SAFe in your organization?" he asks at the conclusion of his video. "If you're starting out new in a small way or have independent small projects it would be best to implement Scrum. As your organization matures, you may eventually evolve practices that are similar to SAFe. If you have a large organization and want to go all out in your strategic planning down to the bottom level engineer, you may be better off starting with SAFe. There is no right or wrong answer. Understand the benefits and pitfalls of both the frameworks and choose wisely."

To achieve that level of understanding and make informed choices, you need an in-depth look at these frameworks. You can find out much more about both SAFe and Scrum at VS Live in Las Vegas, a six-day event running March 1 – 6. Learn about all the Code Trip here.

How Are You Going To Get From Business Intelligence to Business Analytics?

Business Intelligence (BI), which like government intelligence sounds faintly like an oxymoron, has been around a long time. The earliest reference to business intelligence appeared in 1865, according to a Wikipedia article. In more modern times, the term started to appear at IBM in the late 1950s but Gartner is quoted as saying BI didn't gain traction in the corporate world until the 1990s. So it appears to be a term coined at the end of the Civil War that then moved into common usage with Decision Support Systems for data-based tactics and strategies, which were developed from 1965 to 1985. Any way you look at it BI is not new technology.

Fast forwarding to the present where massive amounts of data are being gathered from the huge surge in IoT devices and processed by increasingly sophisticated Artificial Intelligence software, the new term is Business Analytics. This is not your grandfather's punch cards being fed into water-cooled mainframe computers. It's not even business analysts working with Lotus 123 on MS-DOS PCs in 1985. Business Analytics is a whole new ballgame and if you want to play in the game, you may need to upgrade your skillset.

How Much Data Is Too Much?
With IoT and other edge computing systems collecting billions and billions of event and process data, some industry watchers are predicting a "Data-apocalypse" where there will be more information than cloud storage can handle or AI can analyze. But a more optimistic view is that the vast amounts of data being gathered globally present an unprecedented opportunity to give business decision makers a wealth of facts organized in applications for developing tactics and strategies. How are products really doing in the marketplace? Are the processes that create those products as efficient and safe as they could be? Who actually wants to buy what you are selling? Business analytics offers the potential to greatly reduce the guesswork that amounted to little more than a coin flip in old time decision making.

From Theory to Applications
Of course, this is not going to magically appear on business users desktops. Applications need to be built to meet the specific business analytics needs of individual companies, departments and groups. There are tools developers can use to get those jobs done, including Microsoft Data Platform technologies such as SQL Server, Azure SQL Server, and even good old Power BI.

There is news this month on updates to some of the Microsoft technologies specifically to help handle big data.

On Nov. 5, Azure Data Studio was released which is designed to provide multi-database, cross-platform desktop environment for data professionals using the family of on-premises and cloud data platforms on Windows, MacOS, and Linux. More information about it is available on this GitHub page.

The recently released SQL Server 2019 (15.x), SQL Server Big data Clusters is designed to "allow you to deploy scalable clusters of SQL Server, Spark, and HDFS containers running on Kubernetes," as explained in a Microsoft post What are SQL Server Big Data Clusters? "These components are running side by side to enable you to read, write, and process big data from Transact-SQL or Spark, allowing you to easily combine and analyze your high-value relational data with high-volume big data. SQL Server Big Data Clusters provide flexibility in how you interact with your big data ... You can query external data sources, store big data in HDFS managed by SQL Server, or query data from multiple external data sources through the cluster. You can then use the data for AI, machine learning, and other analysis tasks."

That Microsoft post provides scenarios for making use of big data for analysis tasks utilizing AI and machine learning.

Get Up to Speed with an Expert
If you are interested in enhancing your Business Analytics skill set including gaining greater knowledge of the Microsoft Data Platform technologies such as SQL Server, Azure SQL Server, and more, there's a workshop for you this month at Visual Studio Live! From Business Intelligence to Business Analytics with the Microsoft Data Platform is an all-day workshop that is part of Visual Studio Live! in Orlando, Florida, Nov. 17 -22. It is being taught by big data expert Jen Stirrup, who is a Microsoft Data Platform MVP.

This workshop will cover real-life scenarios with takeaways that you can apply as soon as you go back to your company.

Here are the topics included:

  • Introduction to Analytics with the Microsoft Data Platform
  • Essential Business Statistics for Analytics Success: the important statistics that business users use often in business spheres, such as marketing and strategy.
  • Business Analytics for your CEO – what information does your CEO really care about, and how can you produce the analytics that she really wants? In this session, we will go through common calculations and discuss how these can be used for business strategy, along with their interpretation.
  • Analytics for Marketing – what numbers do they need, why, and what do they say? In this session, we will look at common marketing scenarios for analytics, and how they can be implemented with the Microsoft Data Platform.
  • Analytics for Sales – what numbers do they need on a sales dashboard, why, and what do they say? In this session, we will look at common sales scenarios for analytics such as forecasting and 'what if' scenarios, and how they can be implemented with the Microsoft Data Platform.
  • Analytics with Python – When you really have difficult data to crunch, Python is your secret Power tool.
  • Business Analytics with Big Data – let's look at big data sources and how we can do big data analytics with tools in Microsoft's Data Platform.

Microsoft Cognitive Services Designed to "Democratize" Machine Learning

Any developer can get into building Artificial Intelligence apps with Microsoft Cognitive Services.

Just as in the pioneering days of ecommerce, you could build an online retail store app by dropping in a shopping cart web service, Microsoft wants to empower you to create AI apps by adding pre-built cognitive services.

Suddenly your next app can include machine learning capabilities for speech recognition, text analysis, image recognition, and decision support. The best part is you don't have to be an AI guru or a data scientist to build that app. That is the democratizion of AI that Microsoft is hyping.

As the company says in a recent post explaining Cognitive Services and machine learning: "You don't need special machine learning or data science knowledge to use these services."

If you know how to work with REST and APIs you're good to go as a Microsoft blog defining cognitive services states:

"Cognitive Services are a set of machine learning algorithms that Microsoft has developed to solve problems in the field of Artificial Intelligence (AI). The goal of Cognitive Services is to democratize AI by packaging it into discrete components that are easy for developers to use in their own apps. Web and Universal Windows Platform developers can consume these algorithms through standard REST calls over the Internet to the Cognitive Services APIs."

Applications: Meet LUIS
All this data science abstraction is interesting but how does it work in a real world app? Microsoft has examples, such as its cognitive service called LUIS explained here:

Language Understanding (LUIS) is a cloud-based API service that applies custom machine-learning intelligence to a user's conversational, natural language text to predict overall meaning, and pull out relevant, detailed information.

A client application for LUIS is any conversational application that communicates with a user in natural language to complete a task. Examples of client applications include social media apps, chat bots, and speech-enabled desktop applications.

Welcome to Cognitive Computing
Apps like a LUIS-powered chat bot fall into the brave new world of cognitive computing, which Wikipedia defines in this article.

"Cognitive computing (CC) describes technology platforms that, broadly speaking, are based on the scientific disciplines of artificial intelligence and signal processing. These platforms encompass machine learning, reasoning, natural language processing, speech recognition and vision (object recognition), human–computer interaction, dialog and narrative generation, among other technologies."

As the article goes on to explain, cognitive computing is basically AI technologies being used to act like a human in interactions with actual humans. LUIS will help you create a chat bot to talk to visitors to your website or online retail store.

Microsoft Content Moderator is a service that acts like a human editor checking to make sure content posted to your site does not contain offensive material. The company envisions lots of jobs for this cognitive service including:

  • Online marketplaces that moderate product catalogs and other user-generated content.
  • Gaming companies that moderate user-generated game artifacts and chat rooms.
  • Social messaging platforms that moderate images, text, and videos added by their users.
  • Enterprise media companies that implement centralized moderation for their content.
  • K-12 education solution providers filtering out content that is inappropriate for students and educators.

Considering all the news and controversy surrounding online postings, working with this technology may be a hot zone.

Cognitive Service is different from machine learning
But before you start featuring yourself as a machine learning aficionado, Microsoft hastens to add that there are differences between ML and its cognitive services offering. 

"A Cognitive Service provides a trained model for you," the company states. "This brings data and an algorithm together, available from a REST API(s) or SDK. You can implement this service within minutes, depending on your scenario. A Cognitive Service provides answers to general problems such as key phrases in text or item identification in images."

If you're going to get into ML, you are going to need to up your AI and data science skill levels.

As Microsoft differentiates it: "Machine learning is a process that generally requires a longer period of time to implement successfully. This time is spent on data collection, cleaning, transformation, algorithm selection, model training, and deployment to get to the same level of functionality provided by a Cognitive Service. With machine learning, it is possible to provide answers to highly specialized and/or specific problems. Machine learning problems require familiarity with the specific subject matter and data of the problem under consideration, as well as expertise in data science."

Okay, so it's back to the classroom if you want to learn to do all that stuff.

Learn AI Application Development
At Visual Studio Live in Orlando FL, Nov. 17-22, 2019, there is a track where you can Learn AI Application Development.

"Artificial Intelligence is changing how you build apps," states the course description. "Technologies like advanced machine learning, natural language processing, and more, mean you can build truly 'smart apps'. With today's accelerated development cycles, you need to be ready to build the next generation of self-learning applications. In this track, you'll find talks on interacting with intelligent agents like Alexa and Google Assistant, Microsoft's Cognitive Services, Azure Machine Learning, Databricks and DevOps for AI."

Azure AD B2C Offers an Identity Expert in a Box

If you are developing business to consumer applications but you're not an expert in configuring secure identity management, Microsoft says it can provide everything you need with its Azure Active Directory (AD) Business to Consumer (B2C) identity offering.

AD B2C will do all the heavy lifting when it comes to things like third-party authentication, Single Sign On (SSO) and even protection against Denial of Service and brute force password attacks, the Redmond-based software company says.

To show how easy it is for developers to use, Microsoft produced a YouTube video titled What is Azure Active Directory B2C? In the video, posted this month, Adam Stoffel, Senior Product Manager Azure AD, makes a bold statement: "Microsoft will act as the secure front door to any of these applications and we'll worry about the safety and scalability of the authentication platform."

Azure AD B2C is what Stoffel calls "a white label authentication solution," which developers can customize with the look-and-feel of their web or mobile app with a little HTML, CSS, or JavaScript programing. While B2C, as the Microsoft people refer to this product, is busy in the backend making sure the customers logging in are who they say they are and aren't bad guys, your customers will feel they are interacting with your company. For their convenience, your customers can use their social identities, including Twitter, Facebook and LinkedIn, to sign up and sign on. B2C uses authentication protocols including OpenID Connect, OAuth2, and XAML and can integrate with off-the-shelf software packages.

"B2C can also centralize collection of user profiles and preference information and capture detailed analytics information about behavior and sign up conversion," Stoffel explains. "By serving as central authentication authority for all your applications, B2C provides you with a way to build a single sign on for any API, web or mobile application. We will handle things like denial of service, password spray and brute force attacks, so you can focus on your core business and stay out of the identity business."

Microsoft is clearly assuming most B2C developers want to stay out of the identity business.

The video includes a demo of Azure AD B2C doing its stuff for an online grocery store. It shows how signing up and signing on looks to the user. It also shows how the user profiles can be customized. Say you are allergic to peanuts. The application will flag any product with ingredients that might impact your allergy.

Read All About It
For those developers who actually want to read documentation rather than watch how-to videos. Microsoft has some detail instructions on using Azure AD B2C.

There is actually a written version of What is Azure Active Directory B2C? that is a little more technical and freer of marketing hype. The authors, a committee of Microsoft techies, aim this documentation at all levels of expertise.

"If you're an application developer with or without identity expertise, you might choose to define common identity user flows using the Azure portal," they explain. "If you are an identity professional, systems integrator, consultant, or on an in-house identity team, are comfortable with OpenID Connect flows, and understand identity providers and claims-based authentication, you might choose XML-based custom policies."

This doc covers:

  • Protocols and tokens
  • Tenants and applications
  • User journeys
  • Identity providers
  • Page customization
  • Developer resources

This doc takes about eight minutes to read if you don't move your lips.

There are also links in it to more documentation and tutorials.

Up Close and Personal Training
If your preference runs to hands-on learning rather than watching videos or reading copious amounts of documentation, VS Live! in Chicago, Oct. 6 – 10, offers Reach Any User on Any Platform with Azure AD B2C. Nick Pinheiro, Microsoft Cloud & Software Architect, will be the instructor for this session aimed at the introductory to Intermediate level.

"In this session," the description says, "you will learn how to allow users to login to your web or mobile apps with their social and consumer identities or email address with Azure AD B2C. Technologies include: Azure AD B2C, Azure App Service, API Apps, Xamarin and more."
It will cover:

  • Enabling and configuring Azure AD's Business to Consumer (B2C) identity offering
  • Using the Microsoft Graph API to access the user data in Azure AD B2C
  • Integrating your existing app identity with Azure AD B2C

How Does Full Stack Web Development Stack Up?

Full stack web developers are in great demand with attractive salaries being dangled from job search sites.

Is this job for you?

If you've heard about this employment category and are intrigued by the possibilities, you still might want to look before you leap.

To start with: What exactly are we talking about when we talk about full stack web development?

It is a little like having access to all the rooms in the mansion. As a full stack web developer, you know how to work in the front rooms and the back rooms and you have access to all the connecting hallways and rooms in between.

The upcoming VSLive! in Chicago has a learning experience that is a full track on the full stack. Here's how it's described:

Full Stack Web Development
Web development has become the dominant approach for building enterprise software. To provide your best on every project, you need to understand the server and browser client worlds. On the server there's ASP.NET Core with MVC, the new Razor Pages, and support for building services. The browser client is evolving rapidly, with constant changes and updates to JavaScript, TypeScript, Angular, React, and other related frameworks ...

Topics in this track include:

  • ASP.NET Core intro and deep dive
  • Getting started with Razor Pages
  • Angular 101
  • Managing async data in Angular
  • Designing advanced Angular components
  • Advanced Azure App Services
  • Advanced TypeScript

So there you have the components of what you need to know to get started in the full stack world. There's a lot going on in the Microsoft world with ASP.NET Core as well as Azure, Razor, Angular and Typescript. Are you up to date on these core technologies? Here is the latest news.

Can You Say Azure?
Since Oct. 2008 when Microsoft announced its cloud computing service, Azure has been the most mispronounced product name in history. Do a search on how to say Azure and many variations appear. The American pronunciation is said to be a.zhr.  But a lot of computer industry analysts seem bent on outdoing each other in coming up with different ways to say it. Originally, before Microsoft presumably took the name from an RGB color wheel, azure was a variation of the clear blue sky. Maybe that sky had a fluffy white cloud, hence the Microsoft naming logic.

Anyway onward, Microsoft Azure is a big deal in the computing cloud world and full stack web developers need to know about it. Blockchain, which is big news everywhere, was one of the big news previews highlighted this summer at the Microsoft Build developers conference, as Paul Schnackenburg explained in an in-depth Virtualization & Cloud Review article, A Look at the New Azure Releases & Improvements Revealed at Build 2019. There's a preview of Azure Blockchain Service providing point-and-click creation of fully managed networks with management and governance built-in. "There's also an Azure Blockchain Development Kit," he writes, "which brings connectors for Flow and LogicApps, another move to make adoption of this complex technology easier for non-experts. And the plug-in for Visual Studio Code is going to simplify development."

What's New for ASP.NET Core
With .NET Core 3.0 becoming production-ready, Microsoft is focusing on new features for ASP.NET including top level ASP.NET Core templates in Visual Studio: "The ASP.NET Core templates now show up as top level templates in Visual Studio in the 'Create a new project' dialog," Microsoft's Daniel Roth explained in a July Visual Studio Magazine article. What's New for ASP.NET Core offers summaries of the new features.

Working with Razor and Blazor
If you want to start working on the frontend, Visual Studio Magazine offers a handy how-to guide with code samples. In THE PRACTICAL CLIENT: How to Dynamically Build the UI in Blazor Components by Peter Vogel, he explains: "You have two tools for generating your initial UI in a Blazor component: ASP.NET's Razor and Blazor's RenderFragment." He shows how to use both to integrate with your C# code and also offers a caveat about what you can't do.

Angular 8 Grows Ivy
If you are angling for a full stack web developer position, you need to know your Angular. As a Wikipedia article explains: "Angular is a TypeScript-based open-source web application framework led by the Angular Team at Google and by a community of individuals and corporations." The latest version, Angular 8, was released this past May but the article notes that Google has promised new upgrades twice a year. The future of Angular is Ivy, which is a "backwards compatible, completely new render engine based on the incremental DOM architecture. Ivy has been engineered with tree shaking in mind, which means that application bundles will only include the parts of Angular source code that is actually used by the application." Angular 8 has an opt-in preview of Ivy with these features:

Generated code that is easier to read and debug at runtime.

  • Faster re-build time.
  • Improved payload size.
  • Improved template type checking.
  • Backwards compatibility

As an open source project there are lots of websites for Angular info including https://opensource.google.com/projects/angular, and https://github.com/topics/angular.

Pop Goes the Typescript
"Microsoft created the open source TypeScript language in 2012 and it has climbed steadily in popularity thanks to its unique scheme of providing optional static typing for JavaScript-based coding, among other features," explains David Ramel, editor of Visual Studio Magazine, in a recent article, TypeScript Cracks Top 10 in Programming Language Popularity Ranking. In another article on the latest TypeScript 3.6, the open source project's program manager Daniel Rosenwasser covers the latest features with links so you can take a deep dive into what it all means.

Using ASP.NET Core for Building a Modern DevOps Pipeline on Microsoft Azure

If you are working with earlier versions of plain old ASP.NET, but need to upgrade your skills for Microsoft Azure DevOps, you may be looking to get up to speed on its smarter brother, ASP.NET Core, which is growing in popularity with the developer community.

While C# is the "most loved" programming language, according to a recent survey by developer tooling specialist JetBrains. There is growing regard for .NET Core, according to a recent Visual Studio Magazine article. "… the survey indicates Microsoft's new open source, cross-platform 'Core' direction is gaining traction but still has a long way to go as it usurps the ageing, Windows-only .NET Framework, with .NET Core and ASP.NET Core leading the migration," the article noted.

ASP.NET Core is "a complete rewrite that unites the previously separate ASP.NET MVC and ASP.NET Web API into a single programming model," according to a Wikipedia article. "ASP.NET Core applications support side by side versioning in which different applications, running on the same machine, can target different versions of ASP.NET Core. This is not possible with previous versions of ASP.NET."

Microsoft sought to distance the new framework from the older versions of ASP.NET. The company didn't want it to be thought of as simply an update, so the working title, ASP.NET 5 was changed to ASP.NET Core 1.0 for its 2016 release to highlight its status as a brand new product.

Microsoft has recently published an Introduction to ASP .NET Core that covers what developers need to know about the framework for building cloud-based, Internet-connected applications. It touts the framework's advantages including:

  • Build web apps and services, IoT apps, and mobile backends.
  • Use your favorite development tools on Windows, macOS, and Linux.
  • Deploy to the cloud or on-premises.
  • Run on .NET Core or .NET Framework.

Why ASP .NET Core?
Microsoft is aiming at ASP.NET 4.x developers, said to number in the millions, touting ASP .NET Core's ability to integrates seamlessly with popular client-side frameworks and libraries, including Blazor, Angular, React, and Bootstrap. The company also points out that the new framework provides benefits including:  

Beyond explaining what the framework can do, the Microsoft tutorial page offers developers a step-by-step "learning path" with code samples for a basic app to show how it works. 

Would you rather see how it's done rather than reading the instructions? There is a fun and informative one-hour YouTube video featuring Daniel Roth, program manager on Microsoft's ASP.NET team, covering "Full stack web development with ASP.NET Core 3.0 and Blazor." The highly entertaining host shows an enthusiastic live audience how to build a pizza store web app.

If videos are your thing, Microsoft's ASP .NET Community Standup site offers scheduled tutorials that you can watch live. All the past live events, several of them featuring the irrepressible Roth, are available for replay. Recent episodes also included the June ASP.NET Core 3.0 Preview 6 Release Party.

Hands-on Training for Building a Modern DevOps Pipeline
If you are looking for in-person hands-on training, ASP .NET Core will be in the spotlight on Sept. 29, at VS Live! San Diego. There will be a full-day hands-on lab: Building a Modern DevOps Pipeline on Microsoft Azure with ASP.NET Core and Azure DevOps. 

Attendees will come away with an ASP.NET Core app and a SQL Server Database running in Azure with a full continuous integration / continuous deployment (CI/CD) pipeline managed by Azure DevOps.

The instructors will begin with a review of the current thinking on DevOps. Next will be the planning and tracking phase where the architecture of the app will be broken out and defined. Then the dev & test phase where attendees get feature flags implemented, CI builds working, manual and automated tests, and more. In the release phase, you will learn how to create a deployment pipeline to multiple environments and how to validate a deployment after its release using Azure App Services (both web apps and containers). Finally, the monitor and learn phase will cover analytics and user feedback and how you start the cycle over again.

By the end of the day, you will have a CI/CD pipeline configured, a deployed app, and the hands-on experience on how to build a modern ASP.NET Core and SQL Database solution that runs in Azure using Azure DevOps.

Abstract Data

Big Data Is Big News in AI, ML and IOT

At one time data was mostly a topic for database administrators. Not anymore. With artificial intelligence exploding on the scene, Big Data is a hot topic in the developer world.

The meteoric rise of the Internet of Things (IoT) is creating huge datasets – think terabytes and petabytes – that go beyond what traditional relational database management systems (RDBMS) and legacy software analytics tools can handle, according to a Wikipedia article. Sensory data is pouring in from IoT devices in industries including medical, manufacturing and transportation. That data is useful and sometimes even crucial but those industries need a way to make sense out of it.

A new generation of data analytics applications is needed to deal with what one analyst called the coming "datapocalypse." This presents a challenge and an opportunity for developers if they have the skills and tools to create those apps for business users.

On the tool front, .NET developers recently got good news with the preview of .NET for Apache Spark, which will allow them to more easily use the popular Big Data processing framework in C# and F# projects, according to an article by David Ramel, editor of Visual Studio Magazine.

"Spark is described as a unified analytics engine for large-scale data processing, compatible with Apache Hadoop data whether batched or streamed," the editor explained. "Currently, Spark is accessible via an interop layer with APIs for the Java, Python, Scala and R programming languages. While .NET coders have been able to use Spark with Mobius C# and F# language binding and extensions, the new project seeks to improve on that scheme while paving the way to add more language support."

In its announcement of .NET for Apache Spark, Microsoft said it "… provides high performance APIs for using Spark from C# and F#. With [these] .NET APIs, you can access all aspects of Apache Spark including Spark SQL, DataFrames, Streaming, MLLib etc. .NET for Apache Spark lets you reuse all the knowledge, skills, code, and libraries you already have as a .NET developer."

Microsoft’s .NET for Apache Spark website explains use cases:

  • Large streams of data can be processed in real-time with Apache Spark, such as monitoring streams of sensor data or analyzing financial transactions to detect fraud.
  • Apache Spark can reduce the cost and time involved in building machine learning models through distributed processing of data preparation and model training, in the same program.
  • Modern business often requires analyzing large amounts of data in an exploratory manner. Apache Spark is well suited to the ad hoc nature of the required data processing.

As an open source project, Microsoft says that .NET, which is free, and now includes .NET for Apache Spark, requires no fees or licensing costs even for commercial projects.

There is a GitHub site with a tutorial for developers looking to get started with .NET for Apache Spark.

F# for Machine Learning

Speaking of F#, developers working with the open source, cross-platform language are getting new functionality for ML. The 15-year-old language currently works with Microsoft's ML.NET machine learning framework, but Microsoft says new ML functionality is in the works.

With the latest F# 4.6, Microsoft’s primary focus is on boosting performance for medium-to-large sized solutions, according to an article in Visual Studio Magazine.

"Other work included significant reductions in cache sizes, significant reductions in allocations when processing format strings, removing ambient processing of identifiers for suggestions when encountering a compile error, removing LOH allocations for F# symbols when they are finished being type-checked, and removing some unnecessary boxing of value types that are used in lots of IDE features," Microsoft said.

Updates to F# will now be synched with Visual Studio releases, according to a Microsoft announcement that concluded by telling developers: "With this in mind, you can think of the Visual Studio 2019 release and future updates as a continuous evolution of F# tooling."

ML for the Masses with Azure Update

Developers aren’t going to have all the fun in the AI revolution. The Azure Machine Learning Web UI is being updated for business power users who do not have programming skills, according to Microsoft.

"Emphasizing our mission to scale machine learning to the masses, we now introduce automated machine learning user interface (UI), which enables business domain experts to train ML models without requiring expertise in coding," said Tzvi Keisar, senior program manager, Microsoft Azure. Find out more in this Visual Studio Magazine article.

Microsoft's 3 AI Dev Approaches

The Azure Machine Learning UI, is part of Microsoft’s three pronged approach to AI development, summed up as “Code First, No Code and Drag-and-Drop,” according to a recent Visual Studio Magazine article.

This three-prong approach was outlined by Bharat Sandhu, director of artificial intelligence at Microsoft, to fit different classifications of developers, or "AI authoring models:"

  • Code first: use any tools
  • No code: use automated machine learning
  • Drag and drop: make models visually

Explaining the three approaches for different types of AI authors, Microsoft sees:

  1. Developers and data scientists who want to write code to build machine learning models. They will take the code first model Azure Machine Learning offers.
  2. Business domain experts, who know data, but don't know much about machine learning or code will use Azure Machine Learning's automated machine learning 'no code' option.
  3. IT professionals and experts in statistics or mathematics, who are not coders but want to make their own models, will use a drag-and-drop approach.

So Microsoft is planning a big tent approach to AI development to accommodate as many developers and power users as possible.

AI, Data and ML at VSLive! at Microsoft Headquarters

If you are a developer, who wants to up your skills, AI, Big Data and Machine Learning will be a hot topic at VS Live! Microsoft HQ in Redmond WA, Aug. 12 – 16. Sessions will cover:

DevOps

What Azure DevOps Can Do For You

Everybody involved with any kind of software development has heard the DevOps mantra: "DevOps automates and speeds software delivery." Of course, not everyone practices DevOps because there’s a learning curve and a discipline to follow and that’s not always easy especially in organizations demanding instant application gratification. Despite the hype, getting started in DevOps can be a challenge.

So beyond marketing mantras, what positive things can DevOps do for you?

"DevOps is a practice that unifies people, process, and technology across development and IT in five core practices: planning and tracking, development, build and test, delivery, and monitoring and operations," Microsoft explains in an overview of Azure DevOps. "When practicing DevOps, development, IT operations, quality engineering, and security teams work closely together—breaking down practices that were once siloed. Improved coordination and collaboration across these disciplines reduces the time between when a change is committed to a system and when the change is placed into production. And, it ensures that standards for security and reliability are met as part of the process. The result: better products, delivered faster ..."

If you get the time and training to implement it, DevOps could help satisfy demands for instant application gratification.

There are lots of tools to help developers but for someone new to DevOps, it’s not always clear what does what.

In the Microsoft cloud world, Azure DevOps server and services is designed to smooth the developer’s way into the paradigm.

"Azure offers an end-to-end, automated solution for DevOps that includes integrated security and monitoring," according to Microsoft. "The developer experience of Azure DevOps integrates with the tools of your choice. If you’re a Java developer—great—Azure provides native integrations with Eclipse. If you build with Jenkins, use it to easily deploy directly to Azure. Bring your development, IT operations, and quality engineering teams together to build, test, deploy, monitor and manage applications in the cloud."

Deciphering Microsoft Names

The products sound good but the product naming can get a little confusing. Things have evolved. First of all there is Azure DevOps Services, a subscription-based Azure platform, announced in September 2018, that's hosted from Microsoft's datacenters. Then this March, the Redmond, WA-based company announced Azure DevOps Server 2019, which is designed for organizations that want to deploy it in their own infrastructures or any datacenter. One more clarification is needed because Azure DevOps Server 2019 is replacing Team Foundation Server (TFS). Microsoft says that "Azure DevOps represents the evolution of Visual Studio Team Services (VSTS)" and suggests users of Team Foundation Server 2012 and newer versions upgrade to Azure DevOps Server 2019.

Now, that that’s cleared up, what do these versions of the platform provide for developers wanting to apply the DevOps model to their Azure-based products?

In a blog Introducing Azure DevOps Service, Jamie Cool, Director of Program Management, Azure DevOps, said: "Working with our customers and developers around the world it’s clear DevOps has become increasingly critical to a team’s success. Azure DevOps captures over 15 years of investment and learnings in providing tools to support software development teams."

In announcing the Azure DevOps Server, Cool said it "includes developer collaboration tools which can be used together or independently, including Azure Boards (Work), Azure Repos (Code), Azure Pipelines (Build and Release), Azure Test Plans (Test), and Azure Artifacts (Packages). These tools support all popular programming languages, any platform (including macOS, Linux, and Windows) or cloud, as well as on-premises environments."

As with TFS, developers control where they install Azure DevOps Server and when they apply updates.

Cool says there are major updates from TFS 2018 to Azure DevOps Server 2019, and his key highlights include:

  • The new navigation, which enables users to easily navigate between services, is more responsive and provides more space to focus on your work.
  • Azure Pipelines has been enhanced in many ways including new Build and Release pages, and support for YAML builds.

And for those who would rather let Microsoft manage the maintenance and updates, Cool points out that Azure DevOps Services is available.

"Each Azure DevOps service is open and extensible," according to Microsoft. "You can use them together for a full DevOps solution or with other services. If you want to use Azure Pipelines to build and test a Node service from a repo in GitHub and deploy it to a container in AWS, go for it. Azure DevOps supports both public and private cloud configurations. Run them in our cloud or in your own data center."

Azure and AI

As part of its big Build developer conference earlier this month, Microsoft announced new development features for Azure related to artificial intelligence development with machine learning.

As reported in a Visual Studio Magazine article, the news includes MLOps (DevOps for machine learning) capabilities with Azure DevOps integration. MLOps is designed to provide developers with reproducibility, auditability and automation of the end-to-end machine learning lifecycle.

"We're delivering key new innovations in Azure Machine Learning that simplify the process of building, training and deployment of machine learning models at scale," exec Scott Guthrie announced in a blog post before the conference. "These include new automated machine learning advancements and an intuitive UI that make developing high-quality models easier, a new visual machine learning interface that provides a zero-code model creation and deployment experience using drag-and-drop capabilities and new machine learning notebooks for a rich, code-first development experience."

DevOps in the Spotlight

The spotlight will be on DevOps at VSLive! in Boston, June 9 – 13. It will include a Full Day Hands-On Lab: Building a Modern DevOps Pipeline on Microsoft Azure with ASP.NET Core and Azure DevOps.

"By the end of the day you'll have your own Azure DevOps organization with a CI/CD pipeline configured, a deployed app, and the hands-on experience on how to build a modern ASP.NET Core and SQL Database solution that runs in Azure using Azure DevOps," the lab description promises.
