I am currently on 5.12.0.10 and am trying to use xunit.v3 1.1.0 but can't get NCrunch to build my test projects and it just spins forever. I suspect I am triggering some kind of corner case, possibly related to targeting multiple frameworks. I am able to run tests using `dotnet test` and the VS Test Explorer, so that much does work. The broken branch is public (with submodules) https://github.com/aarondandy/WeCantSpell.Hunspell/commits/test-updates/ for a reproduction.

Hi,

Thanks for sharing this issue with the sample solution.

I was able to run all tests to completion on this solution without problems, so perhaps there is more to this issue than the codebase itself.

Would you mind submitting a bug report while the engine is stuck spinning? Also, could you confirm which tasks the engine is stuck on? It should be possible to examine the list of tasks in the processing queue window to see what is in progress.

It gets stuck on Analyze Assembly. Somehow, this time, 2 of the 3 targets finished analysis. I have rebooted multiple times previously and usually all 3 targets would get stuck like this. I don't know what is different this time to cause the 2 to complete. I sent a report in while the net48 target was stuck, let me know if any other info can help. Now that some of the tests are running I am noticing that they are extremely slow, so that may be a clue as well.

Thanks for sending through the report.

Unfortunately the report didn't contain any useful information about the problem. The hang is not being caused by errors/exceptions being thrown in the environment as far as I can tell.

When running the tests on my side, they perform very well and churning them for a period of time doesn't surface any race conditions in their execution or in the analysis steps.

I've reviewed the configuration you're running in the bug report and nothing looks abnormal.

Do you think you can attach a debugger onto one of the hung analysis tasks and see if you can get a stack trace? If you right-click the column headers in the Processing Queue Window, you can turn on the 'Process Id' column which should allow you to identify the process running under the task. Most likely there is a thread here that is hung on something.

I deleted every test from the project and it still gets stuck on Analyse. I'm starting to wonder if I have some turds stuck in a pipe somewhere. Is there a way I can flush all NCrunch state out which may be specific to my system and not on yours?

Good to hear! Just in case it helps somehow because I was poking around already:

I nuked my .NCrunch_ folder, deleted all tests, and the net48 one seems to consistently get stuck. Also, I am seeing a weird state where the (N) logo stops churning even though it still has an item in the queue. It could indicate some kind of UI error too maybe 🤷.
