The SourceChanged event is a routed event where the event identifier is not publicly exposed. This is because this event plays a potentially critical part in interoperation and should not be allowed to be raised arbitrarily by any other source than the internal implementation of a known PresentationSource subclass (currently, the only such class is HwndSource). When implementing an interoperation solution, you can attach or remove handlers for the event (by calling AddSourceChangedHandler and RemoveSourceChangedHandler, respectively) but you cannot perform other operations normally available to routed events such as class handling, adding owners, or raising the event from an arbitrary element source.

This class overrides the RoutedEventArgs virtual method RoutedEventArgs.InvokeEventHandler, in order to return a type-specific handler when requested by the event system. This SourceChangedEventArgs override does not appear in the class members table in this SDK documentation because it is a protected member implemented by a sealed class.
