[.NET 10, MTP mode] dotent test with --solution option doesn't work as expected and useless in current implementation.

[Romfos]

Describe the bug

dotent test for --solution doesn't work as expected and useless in current implementation

If solution have not only test projects you will get an error:

Test run summary: Zero tests ran
Unhandled exception: One or more errors occurred. (Unable to run your project.
Ensure you have a runnable project type and ensure 'dotnet run' supports this project.
A runnable project should target a runnable TFM (for instance, net5.0) and have OutputType 'Exe'.
The current OutputType is 'Library'.) (Unable to run your project.
Ensure you have a runnable project type and ensure 'dotnet run' supports this project.
A runnable project should target a runnable TFM (for instance, net5.0) and have OutputType 'Exe'.
The current OutputType is 'Library'.)
  total: 0
  failed: 0
  succeeded: 0
  skipped: 0
  duration: 1s 088ms
Error: Process completed with exit code 1.

Steps To Reproduce

0. add dotnet.config for mtp
1. Create new solution
2. Add empty class library
3. Add valid test project with 1 green test. Test project should be configured for MTP
4. run dotnet test --solution <path>.

Expected behavior

Only test project is executed and tests are green

Actual behavior

Test run summary: Zero tests ran
Unhandled exception: One or more errors occurred. (Unable to run your project.
Ensure you have a runnable project type and ensure 'dotnet run' supports this project.
A runnable project should target a runnable TFM (for instance, net5.0) and have OutputType 'Exe'.

Additional context

• .NET 10 RC1
• dotnet.config configured for MTP mode
• MsTest 4.0.0 used as test framework, but looks like this is dotnet test bug

Can you please attach a complete zipped repro for this?

Also please note:

• many fixes went for RC2, so this might have been already fixed.
• dotnet.config was dropped in favor of global.json. We will update the documentation once RC2 is publicly available.

[Romfos]

Okay, maybe I will check RC2 first when it will come

[Romfos]

Issue is no longer valid

[Youssef1313]

Thanks for confirmation @Romfos!

Long story short - if you have Library that have dependency (or dependency of depenedency in my case) on MTP nuget package.
It tries to run this library. Such libraries need to mark as IsTestingPlatformApplication = false in csproj
