Operations

          In classic object or component- oriented programming model offered only single way for client to call a method. Client will issue a call, block while the call was in progress, and continue executing once the method returned.
 
         WCF will support classical Request-Replay model, along with that it also supports One-Way call (call and forget operation) and call back(service to call back the client)

Three modes of communication between client and service are
         
     1. Request -Replay
     2. One way
     3. Callback
