Remarks
Raising an event invokes the event handler through a delegate.
The Cancel method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
For more information about handling events, see Handling and raising events.
Notes to Inheritors
When overriding Canceling in a derived class, make sure to call the base class Cancel(ActivityExecutionContext) method so that registered delegates receive the event.
