respond to an ajax call in c#

Question

I have some javascript files and an html file. The do some stuff, and I'd like to make an ajax call (using jQuery's $.post() method) to a server to get some info, and then do some more stuff. Do I need to set up some sort of scaffolding before I can do this? I have a.cs file now, can I just run that with VC# and have it respond to the requests? I'm not sure where to begin. I've looked a little for tutorials... but the ones on microsoft.com are old; Thanks!

Update : I believe this is ASP.NET MVC

Answer 1

If you're using webforms, you can look atPage Methods

I'm guessing you might be using MVC though, which you may want to refer to this question: PageMethods with ASP.Net MVC

Answer 2

Another option if you're not using MVC would be to use WCF to create a service which can receive the jQuery ajax requests. The project at http://wcf.codeplex.com/ has some support for jQuery $.ajax calls.
