Assembly: Microsoft.Office.Interop.UccApi (in microsoft.office.interop.uccapi.dll)
These events are used to notify an application of a pending invitation for a participant to join an application session as well as the acceptance and acknowledgement of such an invitation. This is a dispinterface. Its members define the event handlers for the events raised by an IUccApplicationSessionParticipant object. To catch the events, a UCC API client must implement these event handlers and advise the event source of the implementation if it is interested in receiving the events. To prevent memory leaks, the client should unadvise the events when it is no longer interested in the events.
