This does not seem to be a normal shutdown situation. A experimental instance for the debugging should be closed by 'Stop Dubugging' button of host VS.

Ok. When instance is closed by 'Stop Debugging' the problem does not occur. I am closing this issue then.

@KarolAntczak I deleted my comment because I realized that the basis of what I said was not clear. I think this issue and fix are reasonable.

Ok. I reopened issue and will apply fix once again.
