We have now released the Dynamic Data Preview on Code Gallery. This release is open to the public and gives us a place to provide more frequent updates. Please go and download the new release and leave us feedback in this forum, your feedback will help us make a better product as we march to RTM.
Also I'm happy to announce that the Web Tools team has released the "Dynamic Data Website Wizard" as part of this release. This is a wizard for selection a database, building a data model, configure the site on a page by page basis and then generating a site built with Dynamic Data controls. They need feedback as well so please give it a whirl. Click the link for a screencast and walkthrough of this new feature.
And finally we have a page with some simple samples. These include a basic scaffolded website, a comparison of what a site looks like in classic ASP.NET and then the same thing with Dynamic Data and finally a sample showing how to display images from a database using some custom field templates.
Please check out the new release and send us some feedback!
The Dynamic Data and Web Tools Team
