Fix for this was added here microsoft/vstest#2491 waiting for #12650 to be merged so our automatic inserting into sdk master passes. Then I will need to make PR against preview8.

In latest .Net 5 preview8 SDK(5.0.100-preview.8.20403.18), Error as below when dotnet test xunit

No test is available in C:\Users\v-danche\source\repos\xunit1\bin\Debug\net5.0\xunit1.dll. Make sure that test discoverer & executors are registered and platform & framework version settings are appropriate and try again.

@vdanche the same change that cause the one above also affected xunit visual studio runner package, I patched it here, please update your version to 2.4.3 xunit/visualstudio.xunit#229 <PackageReference Include="xunit.runner.visualstudio" Version="2.4.3">.

I also updated the dotnet test templates.

@dsplaisted I also added this to the know issues list. I believe there is nothing more to do in this issue and can be closed. But you are assigned so it is your call 🙂

@nohwnd Thanks, this workaround works fine.
