ASP.Net MVC 3 & System.Data.Entity?

Question

I'm creating my first asp.net MVC website(the version 3).

I'm using Entity Framework to get data from my database, so for now, I've a movies list in my database.

I'm trying to do a page which display the list of these movies.

So, the controller seems to be OK, it returns a View(IEnumerable).

In the view, I specified the type of my model:

@model IEnumerable

Movie is a class generated with a T4 template from my edmx, so it is heriting from EntityObject.

Now, when I try to display my page, I'm getting an error, indicating me that I've to import System.Data.Entity:

Server Error in '/' Application.

Compilation Error

Source Error:

But, I've referenced this dll in my project and i've the corresponding using in my controller.

I tried to put this using in the cshtml: @using System.Data.Entity but it doesn't compile with(cannot find Entity in System.Data)

So what should I do?

all my projects are .Net 4(not the client profile)

add the following line to your web.config

<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
