Error when running unit test from console using Visual Studio 17.1

Question

Getting the error below when running the unit test from the command line. This runs fine on Windows 10 machine and is failing in Windows 7.

dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=opencover --logger "trx;LogFileName=unit_tests.xml" --configuration Release

Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I have the same problem with Win Server 2008 R2. .NET 6 is not supported on Win 7 nor Win server 2008 R2: https://github.com/dotnet/core/blob/main/release-notes/6.0/supported-os.md — Karel Kral, Feb 25 '22 at 11:47
Windows 7 SP1 is supported with Extended Security Updates installed. — TrustyCoder, Feb 25 '22 at 18:49

Seems to be related to using Windows 7. The bug is tracked here: https://github.com/dotnet/sdk/issues/24124

As a workaround, you can install an older version of .NET 6.0 which is called "SDK 6.0.103" under 6.0.3 in the download section at Microsoft. You then place a file global.json in the root of your project, containing:

{
  "sdk": {
    "version": "6.0.103"
  }
}

Now your dotnet commands will use that version. It should work with that one. Hopefully there will be a fix.

NET 6.0 and Windows 7 so far worked fine together, even though it seems it's not officially supported anymore.
