Assembly: System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The 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.
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 in a derived class, make sure to call the base class method so that registered delegates receive the event.
