EntityFramework 5 install

I created an ASP.NET MVC4 project in VS 2010, then decided I wanted the 4.5 framework so opened the project in VS 2012 and changed the target framework to 4.5.

I got some compile errors which I am fairly sure were caused by a reference to a version of EntityFramework below version 5.

Eg:

Error 2 The type or namespace name 'Table' could not be found (are you missing a using directive or an assembly reference?) c:\users\saad\documents\visual studio 2012\Projects\MvcApplication1\MvcApplication1\Models\AccountModels.cs 21 6 MvcApplication1

Here are the entries currently in my Web.config file:

<configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>

and ...

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

I had no luck changing the EntityFramework reference to a higher version as it did not appear in the framework list.

Following some advice given to somebody with a similar problem, I tried to use the Package Manager Console to solve the problem. You can see the mess I've got into with it below.

Does anyone have any idea how to resolve this problem?

I do need version 5 for the work I am doing.

If you are using NuGet (if not, do) you may need to remove and add back all your packages so they switch to 4.5. If you open your packages.config you can see the versions.

TableAttribute that caused error comes from:

Assembly System.ComponentModel.DataAnnotations.dll, v4.0.0.0
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\System.ComponentModel.DataAnnotations.dll

So you probably miss reference to this assembly in your project.
