Remarks
Extend the DuplexClientBase<TChannel> class to create a Silverlight 5 client object (proxy) that can be used to connect to a duplex service. Duplex communication between a client and service is governed by a message exchange contract in which either endpoint can send messages to the other independently. A callback object is used to enable the service to set up this bidirectional communication.
