Description

  1. Open Microsoft.ReactNative.sln in VS
  2. Add new project -> C++/WinRT Core App
  3. Build

Expected: project builds
Actual: pre-build restore fails with a bunch of errors like:
1>C:\rnw\vnext\Microsoft.ReactNative.Managed.CodeGen\Microsoft.ReactNative.Managed.CodeGen.csproj : error NU1201: Project CoreAppHost is not compatible with netcoreapp3.1 (.NETCoreApp,Version=v3.1). Project CoreAppHost supports: native (native,Version=v0.0)

Research direction

Reproduce the failure by adding a C++/WinRT Core App to Microsoft.ReactNative.sln in Visual Studio and building it. Start with the restore error in Microsoft.ReactNative.Managed.CodeGen.csproj and the generated project's compatibility information; done means the added project restores and builds without NU1201 errors.
