I'm new to Concordion and just started trying it out.
I downloaded their example "Kickstart" project at https://github.com/concordion/concordion-net-kickstart/releases/tag/v1.2.0 and I also created my own project to get a better sense of how it works.
When I attempt to run my tests in both the Kickstart project and my own project that I created I encounter the same errors:
NUnit VS Adapter 18.104.22.168 discovering tests is started Exception System.NullReferenceException, Exception thrown discovering tests in C:\Users......\concordion-net-kickstart-1.2.0\Kickstart.Spec\bin\Debug\Kickstart.Spec.dll NUnit VS Adapter 22.214.171.124 discovering test is finished
I'm not sure why this is happening or what's causing this as I ran their example project straight out of the box and even then it was tossing back the same exception as my own project that I created.
