 1. Replace `<CLRSupport>true</CLRSupport>` properties with `<CLRSupport>NetCore</CLRSupport>`. This property is often in configuration-specific property groups, so you may need to replace it in multiple places.
 2. Replace `<TargetFrameworkVersion>` properties with `<TargetFramework>netcoreapp3.1</TargetFramework>`.
 3. Remove any .NET Framework references (like `<Reference Include="System" />`). .NET Core SDK assemblies are automatically referenced when using `<CLRSupport>NetCore</CLRSupport>`.
-4. Update API usage in cpp files, as necessary, to remove APIs unavailable to .NET Core. Because C++/CLI projects tend to be fairly thin interop layers, there are often not many changes needed. The [.NET Portability Analyzer](../../standard/analyzers/portability-analyzer) can be used to identify unsupported .NET APIs used by C++/CLI binaries just as with purely managed binaries. Guidelines for determining code portability and updating projects to work with .NET Core APIs are available in the [library porting guidance](./libraries.md#determining-the-portability-of-your-code).
