Remarks
Raising an event invokes the event handler through a delegate.
The StatusChanged 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.
Note
When an activity (Activity A) subscribes to a different activity's (Activity B) StatusChanged event, the Activity property of the associated ActivityExecutionStatusChangedEventArgs refers to the activity subscribed to (Activity B), and the associated Sender object refers to the execution context of the subscribing activity (Activity A).
Notes to Inheritors
When overriding StatusChanged in a derived class, make sure to call the base class StatusChanged method so that registered delegates receive the event.
