Exception when switching projects

See original GitHub issue

Running FD under VS in debug mode, I’m often (not always) getting exceptions when switching projects (dev project and tests project for it), or checking out another git branch.

Exception: System.InvalidOperationException: ‘Collection was modified; enumeration operation may not execute.’ Stack trace:

System.InvalidOperationException occurred
  HResult=0x80131509
  Message=Collection was modified; enumeration operation may not execute.
  Source=<Cannot evaluate the exception source>

I definitely know the problem, but it’s not a simple change if wanted to keep performance. There are many cases involved here. Everything could be locked everywhere, but I think that’s an unacceptable solution.
