EF4 and Code first approach

Question

I want to learn about Code First development in EF4 and after googling about it find out that I must download and install some thing named Entity Framework CTP and use it to develop a project by code first approach.

But I have a question , is it the only solution to do that(Code first develop)? I mean , I SHOULD use the CTP ? is there any solution to use tool that already been in Dot Net 4 or VS2010?

any namespace or class exists in dot net 4 to do that?can you just name them for me? for example after i search i found DataAnnotation namespace. what else that i must use for code first develop?

Answer 1

The Code First Method is officially part of Entity Framework 4.1. You can download and install it via NuGet (http://nuget.org/packages/entityframework). EF is now at version 4.3 or will be soon atleast.
