title: C# WPF 0xC0000005: Access violation
body: <p>While developing a WPF app I encountered this crash.
  I tried with/without debugger, Release/Debug configurations, same result.
  The message <code>0xC0000005: Access violation</code> was shown only in Output window, when I started the app VS appeared to be running it for ~10 seconds, then stopped as if I just closed the app normally, but it never showed.
  Disabling Just My Code and enabling Break for every exception didn't help.
  I have made no changes to the code, and the day before it ran without a problem.
  Re-cloned the git repo, still nothing.</p>
