messages or log files if you are hitting an issue that looks similar to
this resolved bug and you do not yet see a matching new report.
The following classes have finalizers or Dispose overrides that allow the finalizer thread to touch other instances of objects. This is bad because the other objects may have been finalized first, especially during program shutdown, when all finalizable objects are finalized. Some *may* be acceptable but their assumptions need to be explicitly commented as having been audited, since it's a violation of ~every guideline on the topic.
A couple call into remoting, which is particularly suspicious and likely to cause problems.

Guys, could you review the classes discusssed by Michael for the code you own, as it seems that some of these usage patterns can cause trouble down the line.
Is removed - that was an old legacy file - it's unused since some time and wasn't even included in the project.
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.
