David Ebbo’s screen cast is very good for show off the new ASP.net Dynamic Data. No wonder this technique alone will become one of the three major MS web solutions. It’s based on Linq to Sql, and very similar to MVC, or MV without C, because it’s still using webForms with many prebuild view templates. The folder structures are same as rails, each module should name after it’s table/model.
The dynamic field is very handy, I like RenderHint, only concern is it’s build on MS Ajax toolkit which is replaced by JQuery now.
