I have been facing this annoying error for a while which looks like following:
Failed to start debugger: "System.NullReferenceException: Object reference not set to an instance of an object\n at OmniSharp.DotNetTest.TestManager.SendMessage[T]
It occurs when a test was quit in debug session because of some error and I think that puts OmniSharp.Csharp module in some weird state. I tried re-installing the OmniSharp plug-in and restarting visual studio code but seems like error just does not go away.
I have OmniSharp C# version 1.31.1. Any idea on how to resolve this issue?
