EF (Entity Framework) is Microsoft's flagship data access platform -- an extended ORM (Object Relational Mapper) that abstracts the calls to the ADO.Net data access provider underneath. It is an open source ORM framework for ADO.Net and is included as part of .Net Framework. The first version of Entity Framework (EFv1) was released as part of .Net Framework 3.5 Service Pack 1 and Visual Studio 2008 Service Pack 1 in the year 2008.
In using Entity Framework, you can work with relational data using domain-specific objects. Entity Framework has been the technology of choice for building data access layer while working with WPF, WinForms, MVC, WebAPI, WebForms and WCF applications. Here are a few design documents on Entity Framework 7.

This implies that Entity Framework 7 is an extensible and lightweight version of Entity Framework that enables provides support for new platforms and new data stores. Entity Framework 7 is a major redesign of Entity Framework and is the default data stack for ASP.Net 5 applications.
