Remarks
The chat application receives a ChatMessageChangedDeferral class object when requested by GetDeferral. Deferrals are only available if the application has a change event handler added to the MessageChanged event of the ChatMessageStore class. The ChatMessageChangedDeferral class received in the parameters for the event handler is retained for later use to notify the message store that actions related to the changer are complete.
