I installed Beta3 of the ADO.Net Entity Framework today as well as the Visual Studio integration tool and started using it on a project that's not mission critical.  So far my only complaint is that it does not (seemingly) include the capability to apply a Regex to the Table Name-->Entity Name process.  For example, I've gotten into the habit of naming tables in the plural, so "select * from Questions" seems natural, however having an object of type Questions annoys me.  Once I think of (or see someone else's) a means of testing performance vs. raw SQL and decide to actually use this I suppose I can rename my tables, seems a shame though. 

Oh, and, I would like for it to be an actual "shipping" product.
