I think reliable way to repro is to run unit test and try to open another project while debugging

Thanks so much for taking the time to submit this report! I attempted to reproduce this issue based on the bug description with the latest Visual Studio 2017 for Mac Preview version 7.2, and I was unable to hit the problem. If this issue is still occurring for you, please reopen this report and attach a reproduction, ideally starting with a new template project and then adding just the code necessary to demonstrate the issue.
