If you are building for the web and haven't heard of Atlas or even AJAX, then you need to read up my friend! Atlas is going to make your web UI cool again by making it even easier to develop pages that refresh regions instead of the entire page, and take advantage of kewl new controls. Check out the Atlas Control Toolkit and begin developing your own cool web UI experience now with the included controls:
The Toolkit also includes helper classes to help you write your own Atlas controls and Project and Item Templates to get you started.
Have fun, and let me know what you think!
