An unhandled exception of type ‘System.ExecutionEngineException’ occurred in System.Windows.Forms.dll

Cause It uses an older debugging engine which causes the problem. In other words, it is caused when you compile a 32-bit assembly and try to use it from a 64-bit process. Solution Go to Tools > Option > Debugging -> General > un-check the "Use Managed Compatibility Mode".
