Parameters

e
Type: Microsoft.Rtc.Collaboration . . :: . CallStateChangedEventArgs
The strongly typed event argument created for handling the state changed operation. The derived class is expected to downcast the right generic type and expose the event.

Remarks

This allows a derived class to be notified of a state change before a public event is raised. The derived class must override this method and should not make any blocking calls in it.
