vscode-csharp: VSCode "Error processing launch options at field: program" popup when debugging an xunit test

Steps to Reproduce:

Setup a project with xunit:

    using System;
    using System.Reflection;
    using Xunit;
    
    public class Fact2Attribute : FactAttribute
    {
        public Fact2Attribute()
        {
            Type thisType = GetType();
             MethodInfo theMethod = thisType.GetMethod("MyOtherMethod");
             var result = theMethod.Invoke(this, null);
        }

            public void MyOtherMethod(string singleParam){}
    }
        [Fact2]
        public void ATestMethod()
        {           
            Assert.True(false);
        }

Compile and using Code lens press Debug Test

Expected behavior

It should fail before the test runs as we are invoking MyOtherMethod without a param. An appropriate message should be shown.

Actual behavior

I get this window popup:

I don’t get any error messages in console. If I try and run test rather than debug test it seems to completely bypass the test so I end up with:

Total tests: 0. Passed: 0. Failed: 0. Skipped: 0

If I run dotnet test I get the same result as run test in code lens.

Versions:

dotnet 2.1.105 VS code 1.22.2 Omisharp 1.14.0 Ubuntu 16.04.4 LTS

Version 1.23.0 fixed it for me. Thanks!

Not sure why this is in closed state, as the issue persists in C# Extension: 1.22.1 (latest) Closed status made me open similar issue - #3965

@JoeRobich - Any ETA on the release of this fix ? This just made me download VS 2019, just to run the unit tests !

Update

I confirm it worked for me with C# Extension**: 1.23.0 , instructions to download beta helped !

Seems like this should still be open - it’s still an issue in 1.22.1 anyway.
