When I debugging in VS2013 update3, msvsmon.exe crashed when hit at a breakpoint.
It shows \"The debugger\'s worker process (msvsmon.exe) unexpectedly exited. Debugging
I got the same error. No effect after deleting all breakpoints and repairing Visual Studio (I have 2013 Community Edition). The problem was the Bitdefender software. I have Bitdefender Internet Security 2016 and had set Active Thread Control (Modules->Antivirus) to Normal level. But after setting this settings to Permissive the error doesn't show up anymore.
