I blogged many times about the netzkern Web Application Reference Model and how we use ASP.NET MVC, WCF, ASP.NET AJAX and JQuery (which is now fully supported by Microsoft, they seem to like the way we are doing things here, too *smile*). Basically our apps use JavaScript and WCF Services (or JSON Results) to communicate with the server after the page has been initially rendered by the MVC Framework. Microsoft has just release a preview version of ASP.NET AJAX 4.0 which includes several great features that support this development style:

- Client-side templates (similar to Server-side partial renderings like they are used in ASP.NET MVC and Ruby on Rails, for example)
- Declarative instantiation of controls (similar to the experimental XML-Script in "Atlas", which I really liked conceptually)
- Bindings (data-binding on the client, where it belongs if you create real AJAX apps)

Especially in combination with JQuery our client-side work is becoming much easier and more "clean" using those features. Great work, ASP.NET team!
