Microsoft Ajax 4.0 Preview 4

The fourth preview of the Microsoft Ajax 4.0 is now available on CodePlex.  This is an important release because it enables the full client data story, complete with the ability to get changes back to the server automatically.  It’s probably the easiest way to build a data-driven client application.  Features include:

• Getting a client representation of data from an ADO.NET and REST data service.
• Rendering data on the client using templates.
• Declarative instantiation of client components.
• Live bindings, enabling changes in the UI and in the data to be automatically propagated.
• Command bubbling for codeless wiring of events in template-driven controls.
• Data identity and association management for efficient and consistent client-server data exchanges.
• Sending changes back to ADO.NET and REST data services.
