ASP.NET AJAX 4 Preview on CodePlex

ASP.NET AJAX 4 adds to client-side data scenarios for both page and component developers. JSON data from the server can be rendered as HTML UI on the client in a highly manageable and efficient way, using ASP.NET AJAX templates.

A new DataContext component provides full change tracking and identity management on the JavaScript objects and arrays. Changes to the data resulting from user interaction with the client-rendered UI can be tracked in the DataContext, and uploaded to the server at any time, through a simple call to the SaveChanges method. Change sets are uploaded in a single batch request to the JSON service.

A key aspect is support for ADO.NET Data Services.

You can try out. The bits, reference, samples, and source code are available on CodePlex at ASP.NET AJAX 4 Preview 4.

Also included on the site are previews to the updates to ADO.NET Dynamic Data 4.0, WCF REST Starter Kit Preview 2, Lightweight Test Automation Framework Update.

Please notice there is also a great session on ASP.NET AJAX 4 @DevDays!
