In this session, we’ll explore how to bring legacy .NET applications into the future—whether you're upgrading to the latest .NET releases or modernizing your architecture to embrace cloud-native patterns, AI integration, and scalable Azure services.

We'll walk through how Visual Studio can help you plan and execute both upgrades and modernization efforts, using built-in tools and best practices. Learn how to approach long-term upgrades with side-by-side and incremental strategies that minimize disruption and maximize progress.

This session will cover:

  • Upgrading ASP.NET MVC and desktop applications to the latest .NET versions
  • Refactoring for cloud readiness and Azure integration
  • Incorporating AI services into existing apps
  • Using Visual Studio tooling to assess, plan, and track modernization
  • Real-world strategies for gradual upgrades across teams and timelines

Whether you're maintaining enterprise software or evolving mission-critical apps, you'll leave with actionable guidance and a clear roadmap for modernizing your .NET solutions.
