`dotnet test` does not print output for .NET Framework tests for Microsoft.Bcl.Cryptography

[vcsjones]

If you run dotnet test against Microsoft.Bcl.Cryptography, the .NET Framework tests will not print any output of the test execution.

Steps to reproduce on Windows:

1. Check out main
2. Do a build .\build.cmd -rc Release -s clr+libs
3. Run .\dotnet.cmd test .\src\libraries\Microsoft.Bcl.Cryptography\tests\

Observe that it does run the .NET 10 tests, and the output for the building the tests for .NET Framework, but does not actually print the output for the test execution itself

Where is the text execution?

PS E:\code\runtime> 

It will print the output if you explicitly pass the framework like .\dotnet.cmd test .\src\libraries\Microsoft.Bcl.Cryptography\tests\ -f net481

So the binlog tells me that the net481 tests run but for some reasons they don't get printed to the console:

@Youssef1313 can you please take a look? Could be a vstest regression. Note that runtime doesn't use the terminal logger.

[ViktorHofer]

It's indeed tied to the terminal logger being disabled. If I delete the root Directory.Build.rsp file I get the following:

@nohwnd will have the most context on this.

[ViktorHofer]

@nohwnd can you please help us understand this issue when not using terminal logger? See the repro steps in the initial post.

[nohwnd]

I was looking at this and then it got lost to context switch. Putting on my board.

[nohwnd]

I now remember why I did not investigate further, I could not build because of this cmake error:

Even though I have the cmake tool installed via VS. Any tips on fixing that? I did not find it in the repo manual.

[vcsjones]

Any tips on fixing that? I did not find it in the repo manual.

It looks like it is finding Cmake but not a linker. Do you have the MSVC build tools and C++ installed in your Visual Studio workload?

[nohwnd]

yes I belive I do.
