WCF duplex communication

I need to re-write an existing client-server application. The existing application communicate using socket, I have to convert it into WCF.

At server side I n开发者_如何学JAVAeed to

• Monitor connected clients
• Validate client request
• Broadcast live data (comming from diff source).
• Listen to client and respond to it

At client end I need to

• Receive server broadcast and display it on UI.
• Display UI and take input from user
• Submit user data to server and display response

I have chosen tcp protocol on self hosting environment.

I need some immediate level references (link, tutorial, book)...

Have a look at this MSDN article, covers pretty much everything you need to know to build a duplex service in WCF:

You can try this : WCF on MSDN

I don't know if you can get it, but Microsoft book on WCF (course 6461A) is not bad.
