Microsoft released a preview of the ASP.NET 3.5 Extensions today.  This release has new ASP.NET Ajax improvements, ASP.NET Dynamic Data support, new controls for Silverlight and the new ASP.NET MVC (Model View Controller) which can be downloaded here. 

If you would like to get an overview of ASP.NET MVC you can check out Scott Gu's blog (ASP.NET MVC Framework).

The “Atlas” controls don’t get added to the Visual Studio 2005 toolbox by the either the core framework or toolkit installer. Here’s what I did to add them:

1. Create an “Atlas” and “Atlas Control Toolkit” tab on the toolbox by doing a right-click on the toolbox surface and selecting “Add Tab” from the context menu and naming the tab accordingly.
2. Right-click the appropriate tab surface and select “Choose Items…” from the context menu and point to the appropriate assembly

The core “Atlas” assembly, Microsoft.Web.Atlas.dll, is in “C:\Program Piles\Microsoft ASP.NET\Atlas\v2.0.50727\Atlas” directory on my hard drive. Yours may vary based on installation choices. I would recommend IMMEDIATELY removing the WebPartManager and WebPartZone controls from the toolbox. They are not intended to be used directly. For the “Atlas” control toolkit, I added the AtlasControlToolkit.dll from “C:\program files\Microsoft ASP.NET\Atlas Control Toolkit\SampleWebSite\Bin” which is where I installed the sample app that demos all of the toolkit controls.

Once you have done this, you should now have both sets of controls in your toolbox.
