Modernizing and Upgrading your .NET Apps with Visual Studio
summary
Shows how to upgrade a .NET Framework app (example MVC5 / Framework 4.8 → .NET 9) using Upgrade Assistant for side‑by‑side YARP proxying and controller‑by‑controller moves, then uses a Visual Studio extension—GitHub Copilot App Modernization for .NET—to generate a markdown upgrade plan, create a new git branch with commits, and run an iterative build‑fix loop (three iterations in demo) to resolve package, routing and bundle issues; also covers Azure Migrate, system web adapters, Windows Forms/WPF and AI‑driven code fixes.
