>I am currently exploring this feature and its obvious I won't get it in a day or two like I did generics, delgegates etc... Since it seems tied to LINQ to Sql it may take a while to get proficient and uncover all the bells and whistles. I think I finally got the EdmGen to work agaqinst our whole database so now I can experiment some more.

You don't need linq to sql. You'll be using Linq to Entities, Entity SQL or Object Query. Each has its strengths and point of use in the EF.
