问题
I've just installed the ADO.NET entity but I'm still missing the model in New Project. I made a research around the web and I found several solutions that didn't help me a lot. I tried to reinstall the Entity Framework, to add (in my case update) the assemblies from the project, to install the "EFTools.msi" from "C:\ProgramData\Package Cache". Any ideas what's going on? I'm using Visual Studio 2013 from DreamSpark.

The entity Framework Model is a file item, not a project. So create a Class Library first and then in the class library use the Add new item.. to add your ADO.NET Entity Framework Data Model:
