I tried NCrunch 1.44, 1.45.11, and 1.45.12 with no real luck on one of my systems, but the other one seems to work okay.

What I see is the nCrunch.TestHost.x86.exe has stopped working,CheckOnline, Close, or Debug popup.

Thanks for reporting this. I'm wondering if I could ask a few quick questions to help narrow this down:

- Do you experience this problem with all solutions? Or just one in particular?
- How often does the crash occur? Does it happen on every test cycle?
- Do you notice the crash occurs several times in just one test cycle? Or only once?
- If you look in the Processing Queue window after the crash has occurred, can you see the test task that failed to run and the tests associated (they should all be marked with an artificial failure)?
- Does changing the 'Use hosted task runner' global configuration setting make any difference?

Thanks!

1) Just one solution (so far) on just one system (so far). Same solution works fine on other system(s)
2) Every time for all unit tests
3) It seems to happen on the first test in a cycle, and then blocks others. If I explicitly rerun any individual test, it seems to fail. It looks like during automatic testing 2 attempts are made to kick off tests per project, and both seem to fail the same way.
4) It appears that all tests are marked as failed.
5) Originally ran with "True", I changed to "False" and ... still fails in what appears to be the same pattern.

Thanks for sharing these details. My suspicion is that this is being caused somehow by the code under test. If you set a breakpoint on the first line of code of one of your tests (i.e. the opening brace), then choose to debug the test, does it hit the breakpoint?

.. Or otherwise, are you making use of any facilities that will execute at the beginning of EVERY test in your codebase? For example, a SetUpFixture?

I am trying to verify that the code is the same on all systems -- there may be a difference in what TFS is downloading as "current". This seems to have left some lingering Fakes libraries/references on the problematic system.

Okay, I zip'd and ship'd the working source tree from the "good" system to the "broken" system and things now work. So maybe I have something NCrunch related checked in (or missing) from TFS.

Regardless, I think this is a setup/config issue, and not a real NCrunch problem.
