Installing Entity Framework

I'm currently using Entity Framework at my job, but I've recently try to get it on my personal computer but I still didn't find a way to get it. Sure, I've searched on google but not really find any exe and not any thread that explain that.

Thanks to help 开发者_JAVA技巧me out!

** EDIT **

I've now access to System.Data.Entity. But I've not the "Entity Data Model" ... how can I get this tools !!

This might be a bit obvious but have you installed .NET Framework 3.5 service pack 1?

Running programs using the Entity Framework requires only the .NET Framework 3.5 with SP1, as stated by Astrofaes.

Writing EF programs requires Visual Studio 2008 (I also use a Team edition, should work with all editions) with SP1. From the comments above I believe you lack the SP1 (this SP actually adds 3.5 libraries support to VS).

(this would have been a comment to the previous answer had I already the right to comment, sorry)
