The assembly "EntityFramework" could not be found.

Question

I've been working on this MVC 3 application on my home computer for a while now. I'm out of town on a different computer, so I got the project from my source control. This new computer didn't have MVC 3 yet, so I installed it after I copied the project to the new computer.

A lot of my dlls (like MvcContrib.dll) were missing since I didn't set Copy Local to true when I first created the project on my home computer. So I've been going in and downloading all the missing dlls and adding them to my project.

The only one I can't find is EntityFramework.dll. I can't find a download for it, and I don't see it as a .NET dll when I try to add a reference.

enter image description here

I'm getting this warning when I try to build: Could not resolve this reference. Could not locate the assembly "EntityFramework"

Download and install Framework 4.0 and it's included.

This can also happen when you manually remove the EntityFramework reference in a project.

If you've lost the reference you can remove the entry in packages.config for EntityFramework

<packages>
    <package id="EntityFramework" version="5.0.0" targetFramework="net40" />
</packages>

After removal you are able to re-install the package through the Package Manager (Manage NuGet Packages)

Assembly 'EntityFramModel' uses EntityFramework 5.0 which has a higher version thhan the referenced assembly

Since you use your edmx in your webproject you need to reference the same Entity Framework dll in the web project as you have in your library. Your error suggests, that you use a different version of the entity dll.

The Main project probably has a reference to a older version of Entity Framework and thus the older dll is in the build. Make sure that all projects that are using the problematic project have the new reference
