JScript does not support delegates.
In XAML, you can use delegates but you cannot define your own.
It is not necessary to use this delegate for dispatcher operations, but DispatcherOperationCallback and SendOrPostCallback use dynamic invoking.
Partial Trust applications do not support dynamic invoking, so you must use either DispatcherOperationCallback or SendOrPostCallback if the application is going to be running in Partial Trust.
