Error: Project has no runnable target frameworks defined. The Target framework parameter shows net6.0 though, so I'm not sure what the problem is.Microsoft.NET.Test.Sdk to get the unit tests to appear in the test runner, but it also causes this error running it normally. Comparing it to a freshly made unit test project, the csproj looks about the same. I've definitely done something wrong in adding the nunit packages, but I have no idea what.
