Introduction:
What is Duplex WCF service and when we should use it



Answer:
  In a client server scenario a duplex WCF service is a service

  where the server can send messages to the client

  without the client requesting them.

  In the scenarios when an event taking place on the server

  should send a message to your client we should use Duplex WCF service.

  For example a third party application sending message to your

  service and your service must inform itas client

  after receiving third party message.
