Use the EventRegistrationToken structure only if you use native Windows Runtime techniques to add and remove event handlers for Windows Runtime events. If you use the syntax that is provided by the C# or Visual Basic languages to add and remove event handlers, EventRegistrationToken is an implementation detail handled by the compilers.
