ICommunicationObject.BeginClose(AsyncCallback, Object)

ExceptionCondition
CommunicationObjectFaultedException

BeginClose was called on an object in the Faulted state.

TimeoutException

The default interval of time that was allotted for the operation was exceeded before the operation was completed.

This method causes the CommunicationObject to gracefully transition from any state, other than the Closed state, into the Closed state within a default interval of time. The BeginClose method allows any unfinished work to be completed before returning. For example, finish sending any buffered messages). This method calls OnBeginOpen(TimeSpan, AsyncCallback, Object) if the communication object was initially in the Opened state.
