I have a WCF service library and a self-host Winform.

Service features is File explorer including (copy, move, delete, new folder, delete... etc) and Task Manager (run, kill, update list).

Then now I want to add other features like chatting between self-host and client, send an image from client to self-host so when it received, it is shown in a pictureBox in a new form.

Till now I have two endpoints for (Task Manager, File Manager) that runs under one service "MainService".

And I set up all the connections using DotNet 4.0 WCF Configuration and Wizards, and I'm using netTcpBinding.

I need to know how to communicate with between WCF service lib and self-host, so I can append a received chat from client on self-host form's textbox TextBoxChat.

And also call a client callback from self-host when Send button clicked, to send the message from self-host textbox TextBoxMessage. Let's say this's self-host ChatForm


So is it possible to do that in WCF? I would prefer to run ChatEndpoint under MainService, so all Endpoints use one port.

I've already check both of them, too advanced, too complicated .. i just need to know how would i receive message from client to self-host –  Murhaf Sousli May 8 '12 at 20:30
They explain precisely that, what you want is called WCF duplex (wsDualHttpBinding). It doesn't get any simpler. –  Baboon Jun 6 '12 at 12:04
