Hi I'd like to make a simple ajax program.
I'd like to send information from the client to server.
I'd like to send information from the server to client. (Like updates every so often)
Seems simple right? But I can't find anything on this online. All the examples all for wpf talking to wcf. Or silverlight talking to wcf. But not AJAX talking to wcf. Especially when I'm talking about callbacks. not just client sending something to server.
Again, I'd like to do with in http. So ajax talks with full duplex to wcf service.
Can you point me to a tutorial? errr some information on how to do this? it sounds easy and there should be a sample out there. i'm hoping anyway.
BTW: does the client need to poll server in order to do this? and if so, doesn't it beat the purpose of using wcf? I'm thinking the client needs to poll server just so the server doesn't disconnect the client. but if that's the case why don't i just do this with .asmx.
