In addition to the core ASP.NET dynamic data runtime support, the VS web tools team today also shipped a first preview of a new dynamic data project wizard that enables you to quickly get a data driven web-site started.  The wizard allows you to select a database, and then the tables, views and sprocs within it that you want to build a LINQ to SQL data model around:

After creating a data model, the wizard allows you to easily choose dynamic data driven template pages to build UI around it:

You can then choose what type of inserting/editing/updating UI is supported on each page:

And when you click finish it will setup a project with your data model classes and data UI pages setup to run.  You can learn more about the wizard and watch it in action in a blog post and screencast here.
