Event data
Raising an event invokes the event handler through a function. The OnWorkStarted method also allows derived classes to handle the event without attaching a function to the event. This is the preferred technique for handling the event in a derived class.
**Note to Inheritors: **When overriding OnWorkStarted in a derived class, be sure to call the base class's OnWorkStarted method so that registered delegates receive the event.
