Build cannot find entity framework

Question

When I build my project in TFS it cannot find the entity fraemwork, yet when I look in the folder it is there;

I get these error messages;

And so on. What do I need to do to fix this?

It sounds like your build server is not automatically downloading the NuGet packages. I'm assuming you're using NuGet since the build is looking for the dependency in a "packages" folder.

I would check out some of the following articles:
