Use OnShutdown to specify the processing that occurs when the system shuts down. Often, OnShutdown will be similar to the processing in OnStop. This event occurs only when the operating system is shut down, not when the computer is turned off.
OnShutdown is expected to be overridden when the CanShutdown property is true.
