EF 4.3.1 since VS 2011

I need to know if it is possible to use the latest version of EF (4.3.1) with VS 2011 without having to install these CTP components as indicated.

I had these components installed, but I uninstalled them, and since then I can’t add a new edmx file to the target .net 4 project; he complains about the lack of a reference to System.Data.Entity.

Do I need to update VS 2011?

After I uninstalled and reinstalled Visual Studio, I still could not get a red error, so I used the process monitor to register what Visual Studio was doing with System.Data.Entityas a path filter, it turned out that Visual Studio was reading from
