Thanks to all who attended SharePoint Saturday in Kansas City! I presented several sessions in the developer track, including WCF and AJAX on SharePoint 2007.

I've uploaded my slides (WCF in SharePoint 2007, and developing dynamic AJAX applications on the SharePoint platform) to the following SkyDrive folder:

I'll post additional code samples soon-- most code is from my new AJAX book (google: "service oriented ajax"). 

The open source AJAX library for SharePoint that I used, the "SharePoint AJAX Toolkit", is located at http://www.codeplex.com/sharepointajax. Get the LATEST SOURCE CODE, skip the release, as I'm usually pretty lazy at building official releases. You can also subscribe to the project feed here. A quick recap: this library safely wraps the Microsoft AJAX Library and adds a JavaScript control that takes Xml and Xslt URL parameters, and wraps it in an AJAX Xml Web Part.

As a demo, we built a Site Chat component using the XmlControl JavaScript class deployed in a Web Part, talking to a WCF endpoint. The full code for this part is in the code downloads for my AJAX book (google: "service oriented ajax"). Here's a screenshot:

In the next few days I'll post some more details, and the whitepaper for WCF support in SharePoint 2007.

This Saturday I'll be speaking in Kansas City at SharePoint Saturday, a free community training event in Kansas City. I'll be talking on (surprise!) AJAX in SharePoint, along with a lunchtime session on WCF in SharePoint. I'll be posting content from both sessions next week, including a whitepaper on WCF in SharePoint 2007 for developers.
