Firstly, you must decide if multiple clients would need to connect to your program running on the server. If so, you must add a service reference or create a proxy for your client application. If you want your server to “push” messages to your client application/s, you must register a callback from the client to your WCF service. Please read through this link for more information on WCF callbacks.
