The correct way to shut down is to exit the Main function. If you have any threads created, you should signal them to shut down before doing so (setting IsBackground to true when you create them will usually do it automatically).

NOT shutting down after calling Application.Exit(). What is the correct way
to make sure the process is killed completely?

After you call Application.Exit are you verifying that your app process is
actually shutting down (with something like Remote Process Viewer)?
