The IDuplexSession interface is the union of the inbound session, defined by the IInputSession interface, and the outbound session, defined by the IOutputSession interface. Either the inbound session or outbound session can be terminated independently of the other. The outbound session can be terminated synchronously by calling CloseOutputSession or asynchronously by calling BeginCloseOutputSession().

The inbound session can be remotely terminated. The Receive associated with the inbound session starts returning null when that session is shutdown.
