Visual Studio 2012 MVC build error: The type or namespace name 'Infrastructure' does not exist in the namespace 'System.Data.Entity'

Question

Update: The assembly reference to System.Data.Entity is selected in the Reference Manager.

The Setup

I get an error when trying to run an out-of-the-box ASP.NET MVC 3 Web Application. I made no modifications.

I simply chose File > New Project > Visual C# > ASP.NET MVC 3 Web Application and left all the default settings intact.

Under Project Settings, I chose Internet Application for the template, Razor for the view engine, and checked Use HTML5 semantic markup.

I then immediately chose Build > Build Solution which fails and produces this error and five other warnings (shown in the screenshot).

The Error

Error 1 The type or namespace name 'Infrastructure' does not exist in the namespace 'System.Data.Entity' (are you missing an assembly reference?)

Yes, I know...

...this question has been asked — many times — but the answers on those posts do not provide adequate information to solve my problem.

Please, be specific in your response, with step-by-step instructions, as I am new to Visual Studio and its MVC app development framework.

The Question

What would cause Visual Studio not to work right out-of-the-box? This is a fresh install. Is there an update that could have caused this issue or could fix this issue?

Answer 1

I had the same problem and resolved it by adding a reference to Entity Framework. This is done by right clicking "Reference" in Solution Explorer and selecting "Add Referece" Next browse to C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE. Choose EntityFramework.dll.
