Upgrade to modern .NET with GitHub Copilot: Assess → Plan → Execute

From the creator

Upgrading an older .NET app can feel risky—unknown dependencies, breaking changes, and “will this even build?” moments. In this video, I demo the GitHub Copilot app modernization agent inside Visual Studio and walk through the full upgrade workflow: Assessment → Planning → Execution. In this video, we walk through how to upgrade a legacy .NET application to a modern version of .NET using GitHub Copilot App Modernization for .NET. You’ll see a full end-to-end demo of the assessment, planning, and execution workflow, showing how GitHub Copilot helps analyze an existing .NET codebase, identify upgrade issues, and guide the migration process step by step. This is an introductory demo focused specifically on .NET migration, ideal for developers working with older .NET Framework or early .NET Core apps who want a practical, AI-assisted upgrade path.
