Hi duplex contract allows a service to callback to a client. When a contract is defined for a service It is possible to specify a corresponding callbackcontract.The standard service contract defines the operations of the service that can be invoked by the client. The callback contract defines the operations of the client that can be invoked by the service. It is the client's responsibility to implement the callback contract and host the callback object. Each time the client invokes a service operation that is associated to the callback contract the client supplies the necessary information for the service to locate and invoke the callback operation on the client check the below link along with pravin links http://msdn.microsoft.com/en-us/library/ms731064.aspx
