When I run the project (F5) I receive the following exception in IDE:

An unhandled exception of type 'System.AccessViolationException' occurred in System.Windows.Forms.dll
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I have never noticed receiving the same exception when running without debugger (CTRL+F5). This is a WPF project, but exception occurs before the App_ctor is executed, so this is external code, and my application code did not start to execute. This happens sporadically, sometimes it happens only once, and sometimes I run the project and get this message for several times in a roll. Then it does not pop up for 5-6 runs, and then starts again.

Anyone knows why is this happening? I have just installed clean W8.1 64 bit, VS2013 and TFS 2013 (although I had the same problem with W8 and VS2012, but not as often).
