Remarks
Use the CallbackBehaviorAttribute attribute to configure or extend the execution behavior of a callback contract implementation in a client application.
The CallbackBehaviorAttribute must be applied to the class that implements the callback contract. If applied to a non-duplex contract implementation an InvalidOperationException exception is thrown at runtime.
The following properties are available:
The AutomaticSessionShutdown property automatically closes the session when the channel is closed and the callback has finished processing any remaining messages.
The UseSynchronizationContext property indicates whether to synchronize inbound method calls automatically using the current SynchronizationContext object.
