Remarks
This method causes an ICommunicationObject to gracefully transition from the Opened state to the Closed state. The Close method allows any unfinished work to be completed before returning. (For example, finish sending any buffered messages.)
The ICommunicationObject enters the Closing state and remains in it until the transition to the Closed state is completed.
Close returns after the Closed state is reached.
If the default close time-out elapses before the ICommunicationObject is able to close gracefully, the ICommunicationObject is aborted.
If Close is called on an ICommunicationObject in the Created, Opening, or Faulted state, the ICommunicationObject is aborted. If Close is called on an ICommunicationObject in the Closing or Closed state, the call returns immediately.
There is also an asynchronous version of the close method that is initiated by calling BeginClose() and completed by calling Close.
