We recently started to use VerifyTests/Verify on Mstest .Net 8. Projects.

One of my colleagues has an error on local build:

CS0119  ’TestContext’ is a type, which is not valid in the given
context

when accessing the TestContext property in a class like

[TestClass]
    [UsesVerify]
    public partial class ItineraryAttachmentTests
    {
        private async Task<string?> Test( )
        {
           return await DebugSaveAndViewModelAsHtml( TestContext);
        }
}

The error doesn’t happen on other developers machines.
On the GitHub Actions build server the normal build/tests run correctly.
But CodeQL analyser reports the same error:

We were unable to automatically build your code. Please replace the call to the autobuild action with your custom build steps. Encountered a fatal error while running “/opt/hostedtoolcache/CodeQL/2.20.0/x64/codeql/csharp/tools/autobuild.sh”. Exit code was 1 and last log line was: Error: Could not auto-detect a suitable build method. See the logs for more details.

error CS0119: ‘TestContext’ is a type, which is not valid in the given context

The build compiler correctly understands that ‘TestContext’ is a property , implemented in auto-generated partial class , but the analyser doesn’t see the generated class .

Do you have any suggestions, how to avoid the error?

How can we somehow troubleshoot or enforce src/Verify.MSTest.SourceGenerator, if it doesn’t work?

The functionality of the SourceGenerator described in Use attribute instead of base class for MSTest #1193

It is expected that file like the following will be generated:

        {
            get => global::VerifyMSTest.Verifier.CurrentTestContext.Value!.TestContext;
            set => global::VerifyMSTest.Verifier.CurrentTestContext.Value = new global::VerifyMSTest.TestExecutionContext(value, GetType());
        }
    }
}
