We have just released a significant update of the Microsoft Ajax Library (Preview 6).  This provides a set of new capabilities to the client-side AJAX library, and can be used with any version of ASP.NET and ASP.NET MVC projects. 

The major new capabilities are:-

• Better Imperative Syntax: A new, simplified, code syntax for creating client controls.
• Client Script Loader: A new client-side script loader that can dynamically load all of the JavaScript files required by a client control or library automatically, and executes the scripts in the right order.
• Better jQuery Integration: All Microsoft Ajax controls are now automatically exposed as jQuery plug-ins.

To get started, you can download the Preview 6 release from CodePlex or you can access the Microsoft Ajax Library scripts directly from the Microsoft Ajax Content Delivery Network (CDN), by adding the following script tags to your ASP or HTML pages.

        <script src=”http://ajax.microsoft.com/ajax/beta/0910/Start.js” type=”text/javascript”></script>

Happy scripting
