This issue is happening due to MWObjectArray Limitation.
If you have any global objects in your C# code then you will get a Windows® exception on exiting the application. To overcome this limitation, use one of these solutions:
  • Explicitly clear global objects before exiting the application.globalObj.Destroy();
  • Call TerminateApplicationEx method before exiting the application.MWMCR.TerminateApplicationEx();
