I have my service on a web site. I try to run this example, first just the server part: :What steps do I need to take to use WCF Callbacks?
But I get this message: "Contract requires Duplex, but Binding 'BasicHttpBinding' doesn't support it or isn't configured properly to support it."
The Web.config file, doesn't have definitions such 'BasicHttpBinding'. It only has more general defitions. Do i have to add lines to it, or there is a more simple way. Many thanks.
