dotnet test with .NET Framework on Linux/macOS broken w/ .NET SDK 7.0.400 about vstest HOT 12 CLOSED

This is probably the same issue as #4549 and #4627, we inserted fix for that into servicing on 7.0.4xx, and it should be in the next service release. (this has links to the insertion pr #4549 (comment))

Could you try the preview build of 7.0.401 from here please? https://github.com/dotnet/installer#table

from vstest.

Wait, looking at the binaries in 7.0.401, the have the same version as what you show in the console. Something is wrong.

from vstest.

The installer pipeline probably does not produce new builds of 7.0.4xx right now, our insertion is in sdk source code, but the latest insertion from sdk to installer is pretty old. dotnet/installer#16954

So right now you don't have a way to test it I think. 😞

@nohwnd No problem, let me know if/when you have something for me to test.

from vstest.

Also agree that this seem to be the same as #4549.

Checked it again today. The installer build is still old.

Strange, our app build pipeline failed last week on tests, then started working.

But now today I got the same error again:
[ERROR] FATAL UNHANDLED EXCEPTION: System.TypeInitializationException: The type initializer for 'Microsoft.VisualStudio.TestPlatform.ObjectModel.EqtTrace' threw an exception. ---> System.TypeLoadException: Could not load type of field 'Microsoft.VisualStudio.TestPlatform.ObjectModel.PlatformEqtTrace:TraceSourceLevelsMap' (1) due to: Could not resolve type with token 01000019 from typeref (expected class 'System.Diagnostics.TraceLevel' in assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089') assembly:System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 type:System.Diagnostics.TraceLevel member:(null)

Are you building on hosted azdo images? Maybe you've hit an agent that already updated, and then hit another one that was not updated yet, and then an updated one again?

from vstest.

Yeah, Azure DevOps build pipeline and using:

pool:
  vmImage: 'macos-latest'

I got this exception on my source tests:

EasyMicroservices/Serialization#56

from vstest.

7.0.401 was released, I checked the nuget and it has 17.7.1 vstest.console, tried running net481 tests on ubuntu (WSL) and it works. So imho fixed, please someone confirm :)
