Occurs before the thread that listens for system events is terminated.
Assembly: System (in System.dll)
This event is raised as the thread that listens for system events is about to be terminated. System event delegates are invoked using the thread that listens for system events.
Because this is a static event, you must detach your event handlers when your application is disposed, or memory leaks will result.
