Remarks

When programming with .NET, this type is hidden and developers that need an event registration token for advanced event scenarios should use the System.Runtime.InteropServices.WindowsRuntime.EventRegistrationToken type. For most app code, you won't need EventRegistrationToken (or event registration tokens) at all, because the add/remove syntax for C# and Visual Basic languages enables the compiler to generate the registration tokens from a simpler syntax.

In the event subscription model, a delegate registers to receive change notifications from a specified object such as a collection. The EventRegistrationToken is used to remove the delegate as a subscriber of change notifications when notifications are no longer needed.
