Why is it that in debug/runtime after exiting my application I either have to hit stop in debug or use the task manager to actually stop the program from running?
The program uses sockets. Is it possible one is being left open or is there another general reason why this happens?

Thanks

Is your application creating any threads, if so it could be some thread is refusing to terminate cause it's still working. Check this ebook out, I think it explains the procedure involved closing a thraed

if you are closing the program in a window that is not the original window that was created when you hit run, then you have to press the stop button.

Yes it's a multi-socket app which uses a thread for each connection. I will read the e-book and post my findings.

Thanks

I'm aware of the stop button, thanks. My problem also occurs outside of the debugger when the [X] is hit. The process can still be found in the task manager list. (and no I'm not referring to the vhost.exe)

I'm still having the same issue. This is my deconstructor and my RemoveClient method.

To cleanup managed resources derive from IDisposable and carry out your routine in the implementation of the Dispose method. Destructors should be used to cleanup unmanaged resources and wont work as you probably expect for managed types.
