Phil Haack and Scott Hanselman have a nice screencast over on Channel 9 that shows you a bit about the Templated Helpers in ASP.NET MVC 2.0 Preview 1.
You get a peek at Html.DisplayFor and Html.EditFor as well as the attributes in System.ComponentModel.DataAnnotations, etc.
We will be talking about ASP.NET MVC 2.0 Preview 1 at the next Tampa ASP.NET MVC Developer Group Meeting in August!
Check out the screencast here.
