[Solved] WCF CallBack implementation [closed]

Question

I can give you one big advantage. We have an application that involves a client (WPF) and a Windows service. Normally the client calls the service (via WCF) to retrieve and/or save data etc. But, there are times we want the service to send the client a message, to notify the client it needs to perform a certain action (like shutdown or display a message to the user – could be anything). A callback is perfect for this.
