This came up as a result of attempting to upgrade our test projects from .NET Core 3.1 to .Net 6 in our solution that includes a Xamarin iOS app. It happens on the macOS-11 build agent in azure dev ops and also on my development mac running Visual Studio for Mac version 17.4(build 2406). Is it possible to upgrade .net core 3.1 NUnit projects to .NET 6when there's a xamarin iOS project in the solution?266361-buildoutput.txt

Repro steps

  • Open visual studio for mac, click new
  • Under Web and Console in the left pane, click Tests
  • Click NUnit Test Project, click continue
  • Select .NET 6.0, click continue
  • Give the test project a project name, click create
  • Clean and Rebuild the solution, build succeeds
  • Add a new project to the solution
  • Under iOS select App, click continue
  • Give the app a name, click continue
  • On the next screen leave the defaults, click create
  • Clean solution, fails

I'll include the sample solution and also the build output.
