VSTest with coverlet collector fails

[arabelaa]

Description

I have a .NETCore 3.1 test project with "Microsoft.NET.Test.Sdk" 16.7.1 of and "coverlet.collector" 1.3.0.

I am getting an exception when running tests using VSTest - Version 16.7.0 (I can't switch to dotnet test approach, unfortunatly - there is a strong requirement to stick to vstest)

Steps to reproduce

vstest.console.exe --collect:"XPlat Code Coverage" C:\Projects\test\Web.Tests\bin\Debug\Web.Tests.dll /TestAdapterPath:C:\.nuget\packages\coverlet.collector\1.3.0\build --Diag:"C:\Projects\diag.txt"

Actual behavior

I get the following warning in the console:

Data collection : Unable to find a datacollector with friendly name 'XPlat code coverage'.
Data collection : Could not find data collector 'XPlat code coverage'

Diagnostic logs

And in diag.txt file I see:

datacollector.exe, TestPluginDiscoverer: Failed to get types from assembly 'coverlet.collector, Version=1.3.0.0, Culture=neutral, PublicKeyToken=4beb1ad7f05a1c71'.

I followed the discussion mentioned on #2278 but it seems like a separate issue.
Am I am missing a configuration?

I can't figure out the source of the problem. Any help is highly appreciated. Thanks in advance.

Initially I opened an issue on coverlet repo but I think it's a VSTest issue.

Based on the answer I received on #2278 I will close the issue.
