SPAs, MVVM, ASP.NET and More: Visual Studio Live! Washington, D.C. Webcast Recap

If you missed our most recent Visual Studio Live! Washington, D.C. preview webcast on Tuesday, May 9, fear not. You can always log on and listen in here. Or even if you did attend this webcast, you can always listen again to review what was covered. Ben Hoelting gave us a free preview of his sessions coming up at the Washington, D.C. event on June 12-15. His webcast was entitled "Web Dev with MVVM and Aurelia: #VSLive Washington, D.C. Preview."

Ben will be presenting the following sessions at Visual Studio Live! Washington, D.C.:

During the webcast, he gave us a sneak peek at what he'll be presenting during his sessions. In his session "Building Single Page Web Applications Using Aurelia.js and the MVVM Pattern," Ben will discuss web development, the MVVM Pattern itself, and then describe some of the details about the JavaScript frameworks that enable the MVVM Pattern for the Web, and explain how to also use Aurelia, TypeScript, and ASP.NET MVC. "Modern browsers have also come a long way," he says. "The browser has become your compiler, your development environment."

Ben clearly has a lot of respect for JavaScript, as you'll hear when you listen in to the webcast recording or see Ben live at the event in DC. "Why JavaScript at all?" he says. "JavaScript is the one true cross-platform language we have right now. Any device knows how to deal with JavaScript." He continued by elaborating on how JavaScript works with other current web development technologies.

Moving on to discuss his next session, "Tools for Modern Web Development," Ben explains why ASP.NET is more openly and completely embracing open source; talk about tools like NPM, Bower, Gulp, Webpack and Yeoman; and describe some of the best practices for using these tools. During the webcast, he spoke about some of his favorite tools and how he uses them. He advises you pay attention to the constantly shifting landscape of these modern web development tools. "Some of these tools change daily, very rapidly," he says. And it's not just the tools themselves, but all the other components. "Also different frameworks have adopted different types of this technology."

Simple Visual Studio Unit Testing Examples to Get Your Feet Wet

Howdy readers, Lafe here. About once a month, my partner in crime, Rich Seeley, has been doing technical takeovers of this blog. Here's his latest post, which looks at a few Visual Studio unit testing examples.

Unit tests are not universally popular among developers and not everyone uses them. But those who use the method seem to love the process.

"Unit tests allow you to make big changes to code quickly," writes one fan on a blog refuting unit test skeptics. "You know it works now because you've run the tests, when you make the changes you need to make, you need to get the tests working again. This saves hours."

Assuming you are not a total skeptic and at least want to get your feet wet with Visual Studio unit testing, there are resources to help developers step into the waters.


This Walkthrough’s for You

For users of Visual Studio 2005 through 2017, Microsoft offers a Walkthrough for Creating and Running Unit Tests for Managed Code, which promises to "step you through creating, running, and customizing a series of unit tests using the Microsoft unit test framework for managed code and the Visual Studio Test Explorer." You start with a C# project that is under development, create tests that exercise its code, run the tests, and examine the results. Then you can change your project code and re-run the tests.

The walkthrough is comprehensive and provides the code you need for each of these steps:

  • Create the first test method
  • Build and run the test
  • Fix your code and rerun your tests
  • Use unit tests to improve your code

The goal of unit testing is improving code. Optimistically, the walkthrough concludes: "the work that we did improving our test code led to more robust and informative test methods. But more importantly, the extra analysis also led to better code in our project under test."

If you want to see before you do, there are, of course, YouTube videos that will help you get started with Visual Studio unit testing.


Live Unit Testing (LUT) in Visual Studio 2017

Live Unit Testing in Visual Studio 2017 is a Microsoft video with Joe Morris, Visual Studio program manager introducing you to the latest unit test features. He explains that the real-time feedback helps developers be more productive even if they are thrown into a project that they may not have worked on before.

"Imagine you’re fixing a bug in a code base with which you’re not completely familiar. With Live Unit Testing you can know right away as you’re typing code that you’re not breaking any parts of the system,” Morris explains. “Getting this feedback right in the code editor as you type will give you extra confidence and make you more productive."

Morris goes on to explain that with Visual Studio 2017, LUT is "just a click away." From the top level menu bar, you go to test command and click start. But you have control of when live unit testing runs, so you are not stuck with it finding errors in cases where you are refactoring and know the code is broken. A drop down menu gives you options to pause or stop testing, and, of course, restart when you are ready.

LUT gives you icons in the left column of your screen so you see exactly which lines of code are passing or failing. A green check means the line is passing. A red x tells you a line is failing. If no test applies to a line of code, it gets a blue dash.

When you make a change to a line of code, a little clock icon appears in the left column to tell you LUT is running for that line, so you know it is working. When the test is complete, the familiar green check or red x lets you know the result. The test took seconds in the demo. Of course, your results may vary.


LUT Gives You Options

To find out exactly what test or tests the code is failing, you can hover over the red x and a pop-up will show you the test it has failed. Since multiple tests may apply, those that the code is passing will have the green checkmark. You can dive deeper into the failed test to find out what is going wrong to help you with debugging. This can be done without pausing or stopping LUT, which will run in the background.

When working on code for a number of projects, another option in LUT lets you specify just the project you want to test, which speeds up the testing process.

Boosting developer productivity by reducing manual steps for testing was the key feature Morris touted in his demonstration of Visual Studio LUT.

Unfortunately, this is not yet available for all Visual Studio users.

On the video, Microsoft notes: "Live Unit Testing is present in the Enterprise edition of Visual Studio 2017 and it's available for C# and VB projects that target the .NET Framework."

One viewer of the video complained that it is not available in the Community Edition.

Hopefully, the Visual Studio folks at Microsoft will hear his plea.

Dealing with Design: A Few UX/UI Design Blogs Worth Checking Out

Developers are developers. Designers are designers. It reminds me of the quote, "East is East and West is West, and never the twain shall meet," from Rudyard Kipling's poem The Ballad of East and West. While that is indeed true with compass points, you can't develop websites without an eye to design. If a site looks clunky or is tough to navigate, no one will go there. I once again turn to the blogosphere to see what I can find.


Addy Osmani

One that caught my eye was Addy Osmani's blog. He is an engineering manager with Google. One of Addy's recent posts works through JavaScript Start-up Performance.

"As web developers, we know how easy it is to end up with web page bloat. But loading a webpage is much more than shipping bytes down the wire. Once the browser has downloaded our page's scripts it then has to parse, interpret & run them. In this post, we'll dive into this phase for JavaScript, why it might be slowing down your app's start-up & how you can fix it."

Some of his other posts get into Progressive Web Apps with React, Offline installation of npm packages, Getting started with Progressive Web Apps, Instant Loading Web Apps with a Service Worker Application Shell Architecture, and Auto-formatting JavaScript code style with JSCS.


Boxes and Arrows

Boxes and Arrows is a compendium of articles and posts around the subjects of design and development. In "Make the Commercial First," Steve Turbek writes, "If an app launches in the app store, and no one hears it, did it really launch? Today, digital products like apps and sites require marketing. Luckily, this has become easier to do, even a limited budget."

Other stories in the Boxes and Arrows quiver include "Designing Progressive Web Applications for the Future" by Mark Pedersen, "How to Avoid UX Burnout" by Benjamin Earl Evans, and "Benchmark Your UX at All Costs" by Ben Rogers.


Billy Hollis

And finally—at least for now—no discussion about UX/UI would be complete without mentioning the one and only Billy Hollis. Many of you have probably caught one of his engaging and entertaining Visual Studio Live! presentations. He's a regular, and with good reason. He knows his stuff and his delivery is right on. Billy posts a blog on the official site for his company Next Version Systems. His recent posts include a whitepaper on XAML application navigation shells, Developer on Fire–User Focus, and one of Billy's latest Channel 9 videos.

So if you find yourself struggling with UX/UI issues as you're developing your next site, there is help out there. You just have to know where to look.

Change Where You Work with Visual Studio Themes

Howdy readers, Lafe here. About once a month, my partner in crime, Rich Seeley, has been doing technical takeovers of this blog. Here's his latest post, looking at some of the themes available for Visual Studio.

Everybody wants a nice work environment. One that is suited to their tastes and temperament and helps them feel positive about their job.

For developers working with Visual Studio, you can change your work environment, or at least, the Integrated Development Environment, with themes.

The basic idea is you may not be happy looking at what Microsoft delivers out of the box.

"If you're unhappy with the stark white-on-black of the editor window, you can select a new theme from File | Preferences | Color Theme...for example,...Light (Visual Studio) theme," explained Peter Vogel, in a Visual Studio Magazine article, A First Look at Visual Studio Code.

If you are new to Visual Studio or have not messed around with themes, Microsoft Developer Network (MSDN) explains it as: "Themes consist of several supporting files, including style sheets for page appearance, control skins to decorate server controls, and any other supporting images or files that make up the theme."

Another Microsoft site, which also has tips on working with themes, explains it in a little more straightforward manner: Themes allow "users to customize the color palette used for menus, toolbars, tabs, title bars, and other environment colors."

Basically, it lets you customize what you see in the IDE.


Helpful Themes

Not all themes are decorative. Some are about accessibility. For developers with visual impairments, the Visual Studio Code site Accessibility page notes: "Visual Studio Code has many features to help make the editor accessible to all users. Zoom and High Contrast colors improve editor visibility, keyboard-only navigation allows use without a mouse and the editor has been optimized for screen readers."

There are instructions on that page for activating a "High Contrast color theme," that would be helpful for the visually impaired.


From Jedi to Humane

There are a wide range of themes out on the Web. If you look here, you'll find a "Dark Theme," a "Jedi Theme," and even a light Earth tone "Humane Theme."

If you prefer a video demonstration of setting colors etc., you can find many on YouTube including How To Import Custom Themes Into Visual Studio, which shows off a Facebook Theme that uses the color scheme of the popular social media site. It also offers a warning that trying to mix and match multiple themes may result in errors. So you may run into trouble trying to combine the Jedi Theme with the Humane Theme.

The Visual Studio Programmer Themes Gallery shows off 12 themes. On that page blog author, Scott Hanselman, tells readers why he thinks themes make a difference: "More and more I find myself skinning and theming my Visual Studio development environment in order to stay frosty. It's surprising how changing your theme (fonts, colors, etc.) can re-energize me when I'm having trouble with some problem or motivation."


More Than One Way to Skin Visual Studio

The reference to skinning refers to another way you can make your Visual Studio environment more colorful and helpful.

As this MSDN post, Customizing Skins, explains: "A skin is a graphic that surrounds the rectangular form, the viewport, of an application in the Device Emulator or Visual Studio Designer. When you use a skin during application development, you can better visualize how your application looks on a real device. You can use the same skins in Visual Studio designers and the Device Emulator." If you need tips on skinning you can find it there.


2017 Themes – Are We There Yet?

Most of the themes and tips for using them refer to Visual Studio 2015 or even earlier versions. There seems to be a reason for that and it may put at least a temporary crimp in your attempt to prettify Visual Studio 2017 if you’ve started working with it.

There's a discussion about the Visual Studio 2017 Color Theme Editor on a Stack Overflow community site that indicates developers are having trouble transferring their favorite Visual Studio 2015 themes to the newly released version.

One member asked: "I used Visual Studio 2015 Color Theme Editor and now I would like to use this extension for Visual Studio 2017. On the other hand, according to The Visual Studio Blog, it has not been updated yet. So, I am wondering if it is possible to use this extension for Visual Studio 2017 by modifying the previous one until the new Color Theme Editor is released."

The answer from several other community members was a definite maybe. One said that the there is a hacked version that lets you use the 2015 themes in the 2017 version. But this is one of those "use at your own risk" deals.

Another writes of problems: "The colors in the VS15 themes [do] not exactly match VS17. For example, binary operators are all black in all non-standard themes of the Theme Editor."

Sooner or later (some developers say "much later") this will all be sorted out, so that everybody can have the theme they want.

Stay tuned.

The Best of ALM Books

Technology continues to change at a dizzying pace. While that is of course true, it's also practically a cliché. What also changes, and indeed more significantly, are the development practices that go along with those technological advancements. Application Lifecycle Management (ALM), agile, DevOps—those have all evolved along the way as well. ALM has been around long enough so there are some venerable references, should you feel the need to beef up your collection of ALM books. If you're thinking of adding a few titles to your development bookshelf, here’s a look at a few ALM books you might want to consider.


Agile Application Lifecycle Management: Using DevOps to Drive Process Improvement

This polished, practical and comprehensive title focuses on agile ALM, encompassing all the essential principles of agile development. The book provides practical advice and strategies for carefully and thoughtfully implementing agile ALM. Examples and guidance in the book show how to fully leverage the benefits of agile without sacrificing any aspects of your current development processes.

You'll learn how to properly manage source code, builds, environments, change control, and releases—all within the structure of agile ALM. You'll also learn how to support agile development within a variety of different organizational structures, whether those groups use traditional development practices, conventional ALM systems, or even non-Agile teams. The book will also guide you through the process of scaling Agile ALM to accommodate larger teams or even remote teams.

Agile Application Lifecycle Management: Using DevOps to Drive Process Improvement includes sections on:

  • Understanding key concepts underlying modern application and system lifecycles
  • Creating your best processes for developing your most complex software and systems
  • Automating build engineering, continuous integration, and continuous delivery/deployment
  • Enforcing Agile ALM controls without compromising productivity
  • Creating effective IT operations that align with Agile ALM processes
  • Gaining more value from testing and retrospectives
  • Making ALM work in the cloud, and across the enterprise
  • Preparing for the future of Agile ALM


Professional Application Lifecycle Management with Visual Studio 2013

While slightly dated and geared toward Visual Studio 2013, this remains a comprehensive and high-level text. Professional Application Lifecycle Management with Visual Studio 2013 provides in-depth coverage and a complete framework for using Application Lifecycle Management (ALM) to streamline software design and deployment processes with Visual Studio. Naturally, the focus is on using Microsoft's well-developed tools and methodologies.

This book fully describes how to use the Microsoft ALM suite of productivity tools with Visual Studio 2013 in a variety of situations and applications. Extensive case studies demonstrate how to apply the development practices described in the book. The hands-on approach the veteran team of authors takes makes adopting Visual Studio's ALM functionality relatively simple. Coverage areas in this high-level text include:

  • streamlined software design and deployment
  • practical overview of ALM with step-by-step guides and reference material
  • case studies to illustrate specific functionality and provide in-depth instruction
  • iOS, MacOS, Android and Java development
  • modeling, designing, and coordinating enterprise software deployments

Hopefully, the authors and Microsoft see enough promise in the subject matter to produce a new edition to cover Visual Studio 2017.


Continuous Delivery with Visual Studio ALM 2015

This book takes ALM a step further and focuses on continuous delivery; specifically Continuous Delivery practices using Visual Studio and TFS 2015. The authors Mathias Olausson and Jakob Ehn are both Microsoft MVPs. They adroitly present the theories behind this methodology and how to best use it in practical environments using real-world examples.

Continuous Delivery with Visual Studio ALM 2015 fully describes the agile and iterative techniques you need to know if you're planning to accelerate your development practices. This is what you need to know if you're going to deliver solid, working software with every release. And this direction is well worth considering. Continuous delivery can help you reduce risk and become more agile and innovative. Continuous Delivery with Visual Studio ALM 2015 delivers:

  • A full definition and description of Continuous Delivery practice, and how to use them to more efficiently develop better apps with Visual Studio 2015
  • How to use Team Foundation Server 2015 and Visual Studio Online to plan, design, and implement powerful and reliable deployment pipelines
  • Detailed step-by-step instructions for implementing Continuous Delivery on real projects

Stay tuned for future blog posts featuring TFS and VSTS books! Know of any more great ALM books? Drop me a line at llow@1105media.com.

Getting Started with ASP.NET Core Tutorials

If you’re developing apps or services for the web, you’re bound to be using ASP.NET. This language framework is one of Microsoft’s gifts to the development world for building dynamic web sites, apps and services. It has been around since early 2002. It actually succeeded Microsoft's Active Server Pages (hence the ASP in ASP.NET) technology.

And now there’s ASP.NET's successor ASP.NET Core. The Core version is built around a new open-source, cross-platform .NET compiler. Codenamed “Roslyn” when it was under development, it was often jokingly referred to as the “worst kept secret at Microsoft,” since they didn’t seemed as concerned about secrecy as they often do when new releases are in the works.

So you’re developing web apps and services and you want to become more proficient in ASP.NET and ASP.NET Core? You’re in luck. Another trip through the blogosphere revealed a healthy handful of ASP.NET Core tutorials. Here’s a look:

ASP.NET Core Tutorials

This is the official Microsoft ASP.NET Core tutorial site. It covers broad categories like building web applications, building web APIs, working with data, authentication and authorization, client-side development, testing, publishing and deployment. These ASP.NET Core tutorials do a good job of taking you right from the start. Under the building web apps category, for example, there are tutorial segments for Your first ASP.NET Core application on a Mac or Linux using Visual Studio Code, Building your first ASP.NET Core MVC app with Visual Studio, and Getting started with ASP.NET Core and Entity Framework Core using Visual Studio.

And in the next category, building Web APIs, there are segments on Building your first web API with ASP.NET Core MVC and Visual Studio, ASP.NET Web API Help Pages using Swagger and Creating backend web services for native mobile applications.

ASP.NET Core Tutorial and ASP.NET Tutorial

This one is part of Tutorialspoint, which also covers the original version of ASP.NET. These are very much first-timer oriented. The ASP.NET Core tutorials cover an overview, environment setup, new project, project layout, exceptions, set up MVC, MVC design patterns, routing, action results, and a handful of other topics.

The regular ASP.NET section they describe as basic ASP.NET programming will bring you to a moderate level of expertise in ASP.NET. The site recommends starting with an understanding of the .NET programming language and other web technologies such as HTML, CSS, and AJAX. The ASP.NET tutorials cover environment, life cycle, event handling, server side and server controls, client side, directors, validators, file uploading, multi views, AJAX control, data sources, data binding, and debugging. There’s a whole list of other specific topics as well. These pretty much cover all the ins and outs of ASP.NET and ASP.NET Core.

ASP.NET Core 1.1 Getting Started Tutorial

Once you’re rolling with ASP.NET and want to branch out to Core, check this one out. This covers the latest and greatest in the latest version. The site recommends, "You basically need to update your project.json file, targeting the version 1.1 of the framework and the NuGet packages. If you are using VS 2015, you might also need to update or create a global.json file that pins the target framework to be used with your project, in case you run into issues with multiple versions installed locally side by side."

The tutorial covers the major new feature areas in ASP.NET Core 1.1, including middleware as filters, the rewrite module, viewing components as tag filters, viewing compilation, response compression and caching, cookie storage for TempData, and some of the other less notable improvements. These are hardcore higher level tutorials, complete with code snippets and detailed descriptions. In the first piece on using middleware as filters, it explains, "If you check the source code, when a middleware is added as a filter, it is effectively being added as a Resource Filter. This means the middleware executes after routing and authorization but before everything else. You now will be able to:

  • Add middleware (your own or third party provided) to particular controllers or actions. For example, you could add the new compression middleware only to particular actions.
  • Use Route features like the RouteData values extracted by the routing middleware.

The first option means greater flexibility. The second might not seem much, but it makes a great difference in some scenarios."

It follows up each topic with code snippets to demonstrate how to do what the tutorial has just explained. There are other ASP.NET and ASP.NET Core tutorials out there, but these were some that rose to the top, in my humble opinion. Let me know what you think at llow@1105media.com.

Visual Studio 2017 Update Brings Cutting-Edge Features to the Forefront

Howdy readers, Lafe here. About once a month, my partner in crime, Rich Seeley, will be doing technical takeovers of this blog. Here's his look at some of the new features in Visual Studio 2017.

Microsoft filled hours of YouTube space this month with the launch of Visual Studio 2017 including this kickoff by Microsoft CEO Satya Nadella, who touted the release as designed to empower developers to build any app on any platform.

"We can’t wait to see what developers do with it," he said.

Once you get past the all-things-for-all developers hoopla, there are some cool cutting-edge features in this Visual Studio update. Not surprisingly, some of the demos that got the most applause from developers at the launch event were automations that speed up coding and debugging.

As a Visual Studio Magazine article pointed out in covering this month’s launch "much of what's new has to do with updates to tools that aim to increase developer productivity and performance and the current state of several VS iterations, including the Mac and Mobile Center previews...improvements to startup (new Start page) and project loading (also, project loading without the need to have a solution loaded); enhanced navigation, with a host of Go To shortcut keys for grouping, sorting, filtering and searching of references in a Results window; IntelliSense filtering; improved refactoring, style analyzers, and other C# language improvements; support for CMake and Linux (via extension) in Visual C++; live unit testing; new Run to Click in lieu of temporary breakpoints and exception helpers in a non-modal dialog for debugging; and a new, streamlined installer."

As Michael Domingo pointed out in this Visual Studio Magazine post, getting an overview of what’s new in the Visual Studio update can be difficult with so many features being touted in the two-day launch event. But he pointed readers to a poster created by the VS team at Microsoft to show all the new features including Advanced IntelliSense, Live Code Analysis, new shortcut keys for faster development, links to pages for extensions, and a mini-graphic of the many layers of .NET, and language-specific changes. When you spot the new goodies that apply to your work, you can dive into the release notes to get the details.

The Big Picture

While it is tempting to cut-and-paste into this blog the entire release notes, which cover everything from the "new installation experience" to workarounds for things like VS Team Explorer that didn’t make this month's Visual Studio update, there isn't much point since it's easy to scan the notes and find the items you're going to be using for your projects. Here are a few highlights focused on speeding coding, debugging and testing, as well as improving app performance:

  • Visual Studio IDE - A broad range of enhancements in Visual Studio 2017, including reduction in startup and solution load times, sign in and identity improvements, improved code navigation, open folder view, and connected services to enable connections between your app and any service on-premises or in the cloud.
  • Debugging and Diagnostics - Overhaul of the Exception Helper and faster code navigation with Run to Click. Plus, a new summary of your application events in the Diagnostic Tools window and several improvements to the CPU Tool.
  • Live Unit Testing - Visualize unit testing results and code coverage live in the editor.
  • Testing Tools - Associate automation with test case work items using the Test Explorer.

Visual Basic Developers Not Forgotten (Sort of)

You can scan the release notes to find out specifics for the language you use. For example, Visual Basic developers will find these updates:

  • Value tuples introduce language support for using tuples to temporarily group a set of typed values: Dim point As (x As Integer, y As Integer) = GetOffset().
  • ByRef return consumption extends the language to support consumption of functions and properties from libraries which have ByRef returns.
  • Binary literals and digit group separators allow native representation of binary numbers. This is super convenient for bitmasks and flags enumerations: &B1001_0011.

Of course, the Visual Studio update couldn't have everything or please everyone. An article on the ADTmag site noted that despite persistent requests from Visual Basic developers for more support for their language, ADT reported:

Microsoft also stamped DECLINED on:

  • Visual Basic for Developing Universal Windows Application
  • Provide a Visual Basic 6 Community edition - to allow free download of the VB6 programming language
  • VB6 Programming - Create a utility to convert VB.Net to VB6
  • Re-open the 'Bring back Classic Visual Basic' suggestion for VB6 Programming

There Will Be Bugs

As a reminder that any software release is more of a work in progress than a final product, an article on the Visual Studio magazine website, points to this irony: "Even with Team Foundation Server 2017 now out with the release of Visual Studio 2017, the VS team continues to work on TFS 2015 improvements. Just last week, the group released a TFS 2015 Update 4 preview that rolls up with a slew of bug fixes."

So enjoy the Visual Studio 2017 update. And stay tuned.

Visual Studio 2017's Features in a Printable Infographic

Visual Studio Magazine Editor-in-Chief Michael Domingo found this Visual Studio 2017 infographic helpful, and we hope you will too!

Microsoft added a ton of new features and updated functionality to Visual Studio 2017. There is also a lot of partner technology now incorporated directly into the IDE, like Redgate’s database features and Parasoft’s integrated unit testing. There has been a lot going on in the development pipeline throughout the last year since Build 2016. It’s a lot to keep track of, so having a summarized list of all Visual Studio 2017’s new and updated features—both the standard features you use every day, and some unique hidden gems—can help keep you on track.

So that's what the Visual Studio team did, put all of those goodies and hidden gems into an infographic posted on their site and ready for printing. Besides some quick tips on Advanced IntelliSense, Live Code Analysis, and a whole host of new shortcut keys for every facet of development, there are also links to pages for extensions, a nifty mini-graphic of the many layers of .NET, and language-specific changes, all depicted graphically.

You can find the poster here. (You can also view the VS 2017 release notes, which provide the usual text descriptions of all the newness, here.)

If you end up printing this up and posting it, we'd love for you to send photos of you with the wall you tape this poster on. Tell me about it at mdomingo@1105media.com.

Going Mobile, Going Xamarin: Some of the Best Xamarin Blogs We’ve Found

If you're developing mobile apps, you’re developing with Xamarin. Today we look at some of the sharpest Xamarin blogs out there for developers.

Xamarin Blog

This is the official Xamarin blog, so there is plenty of good stuff in here – from individual tips and tricks to links to Xamarin-related webcasts and other resources. Most, if not all, of the contributors are Microsoft employees—including the Xamarin guy James Montemagno, who has presented before and will certainly present again at Visual Studio Live!

A recent post describes the new Xamarin.Forms Previewer that comes with the latest release for Visual Studio and Visual Studio for Mac. There are now enhancements to the Xamarin.Forms Previewer to "increase the range of supported controls and XAML constructs … make the previewer much more reliable, including the initialization process. Be sure that you have the latest Java 1.8 x64 installed, as it is required for Android previewing."

Another recent post by James Montemagno dives deep into .NET Standard Libraries in both Xamarin Studio and Visual Studio. These help you share code more easily. "Consuming .NET Standard NuGets and Assemblies is completely seamless, and with Xamarin Studio 6.2, developers can create and open .NET Standard projects. The .NET Standard Library is a formal specification of .NET APIs that are intended to be available on all .NET run-times. You can think of it as a simplified, yet expanded, Portable Class Library. It is a single library with a uniform API for all .NET Platforms, including .NET Core. You just create a single .NET Standard Library and use it from any run-time that supports .NET Standard Platform."

Speaking of James Montemagno, this is his personal Xamarin blog. As you might suspect, he gets deep into the details of coding mobile apps with Xamarin and supporting technologies. He also covers ASP.NET Core. Linux, Azure and how they all work together. A recent post covers Deploying an ASP.NET Core app to Linux on Azure App Service. He says he has been "messing around with ASP.NET Core inside of Visual Studio for Mac," which is what led him to this topic. His posts are nicely detailed and include screen shots that support and illustrate what he's describing.

Jonathan Peppers

Jonathan Peppers is a self-described "Xamarin MVP and C# nerd." His blog, like Montemagno's, includes a laundry list of specific topics and functions. Some of the top recent posts include Securing In-App Purchases for Xamarin with Azure Functions, Improving HTTP Performance in Xamarin Applications, and Mocking Xamarin.Forms.

That last post isn’t making fun of Xamarin.Forms. Instead, he talks about recreating the forms app. "We've been building a large Xamarin.Forms application for quite some time at Hitcents, and there was a huge pain point I was able to figure out for our team. If you've ever gotten into Xamarin.Forms" development, it becomes quite clear that there isn't a guide for unit testing things like markup extensions, custom views, navigation, animations, etc."

He goes on to describe his solution. "The dilemma is, if you try to setup your own Xamarin.Forms.Forms.Init() for the purposes of unit testing, you quickly find that most of the interfaces needed to set this up are marked internal. To get around this issue I took advantage of [InternalsVisibleTo], and created a unit testing library where I renamed the output assembly to Xamarin.Forms.Core.UnitTests.dll. This allowed me to setup a MockForms.Init() method, and this assembly name isn't likely to conflict with anything in a developer's Xamarin.Forms project."

There are several other top-notch Xamarin blogs out there, so look for another post coming up in which we’ll present several more. Happy coding!
