I have a web MVC project with Entity Framework 4.x working fine.

Now I added a class library project in the same solution, and I have mapped different database tables successfully. .edmx is generated. Then I write a simple test class and try to build the this new project. I got error - The namespace name Infrastructure does not exist in a namespace System.Data.Entity ...

I googled it and was said I need a reference to the EntityFramework or need to install EntityFramework. I'm confused, as I already have a web MVC project working, and also .edmx has been built in the new class library project. So EntityFramework should not be a problem...?

What should do to remove this error?

I may need to add a reference to the class library project in the existing web project, so that the web project can use classes defined in the class library project, right?

I appreciate any help.

Do you have a using statement to the Infrastructure as shown below. This namespace is found in the EntityFramework.dll so make sure that the project this is in has the Entity Framework dll as well.

using System.Data.Entity.Infrastructure;
