Create a web service to push messages to clients
-
Thanks, this is correct. I just looked at some articles and accordingly if we use basichttpbinding we cannot create duplex service but with wshttpbinding we can. but with it then we need to make sure that ports, firewall issues are taken care of on client machine. I am not sure but there should be some way using using basichttpbinding by which i can create callback methods.
You obviously don't have even the most rudimentary understanding of the mechanics of a web service. Once more, a web service is a request/response system, and nothing more. If you want to "push" data somewhere, you cannot do it with a *web* service. If you want to push data without it being requested, your best bet is to use a *windows* service that listens for connections, and broadcasts the data (via WCF or some other transport mechanism) to any client that might be listening and that knows how to interpret and react to the data being pushed.

I want to create a web service for a chat application which will instead of Request/response model use push model. Client app will be notified of a new message, user logged in etc.. by the web service. Does anyone have know where to start any good article with basic knowledge for creating such push web services.
You could always have a little node.js server up and running, and when various client actions occur (log on, etc), it sends a message to your node.js server, which would then broadcast another (push) message. And then the client "listener" js file on your front end could handle the pushed message in whatever way you see fit. And basically any active client node would accept the message/action.
