Activity.StatusChanged Event

Raising an event invokes the event handler through a delegate. For more information, seeRaising an Event.

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.

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).

When overriding StatusChanged in a derived class, make sure to call the base class StatusChanged method so that registered delegates receive the event.
