Dynamic Data IObjectContextAdapter missing reference

Question

I have a fresh install of VS2012 with Update 2. I create a new project of "ASP.NET Dynamic Data Entities Web Application". I then add an "ADO.NET Entity Data Model" which I generate from an existing SQLServerExpress database.

However when I go to build the solution i get the following error:

The type or namespace name 'IObjectContextAdapter' could not be found (are you missing a using directive or an assembly reference?)

That appears to be declared in System.Data.Entity.Infrastructure but I cannot find that assembly anywhere. I have verified that I have EF5 is installed for the solution as my packages.config shows:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="5.0.0" targetFramework="net45" />
</packages>

The EntityFramework reference properties shows:

RuntimeVersion: v4.0.30319
Version: 5.0.0.0

and in web.config I have:

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

This looks wrong as it should say 5.0.0.0? However changing it has no effect whatsoever. Can someone please point me in the right direction?

Answer 1

Getting this to compile turned out to be very easy. I needed to add:

using System.Data.Entity.Infrastructure;

to Global.asax.cs. Seems that the T4 template does not include this be default.

Answer 2

<%@ Import Namespace="System.Data.Entity.Infrastructure" %>

adding this line to the top of the global.asax works as well.
