 In this article, you'll learn about different ways you can modernize your app after it's been upgraded from .NET Framework to .NET. Use the [.NET Upgrade Assistant](upgrade-assistant-overview.md) tool to upgrade your app to .NET.
 
+> [!TIP]
+> You can use GitHub Copilot to modernize your application after migrating from .NET Framework. For more information, see [What is GitHub Copilot app modernization - upgrade for .NET?](github-copilot-app-modernization-overview.md).

 ## Missing APIs
 
 When upgrading a .NET Framework app, you'll most likely have some incompatibilities. This is because .NET Framework is a Windows-only technology and .NET is a cross-platform technology. Some libraries aren't. For example, .NET doesn't provide out-of-the-box APIs to access the Windows Registry like .NET Framework did. Support for the Windows Registry is provided by the `Microsoft.Win32.Registry` NuGet package. Many .NET Framework-specific libraries have been ported to .NET or .NET Standard, and are hosted on NuGet. If you find a missing reference in your project, search NuGet.
