.edmx file extension

.edmx

Entity Framework classes file.

A .edmx file contains the model definition in an ASP.NET MVC (Model View Controller) application.

Microsoft MSDN describes the .edmx file as:

An .edmx file is an XML file that defines a conceptual model, a storage model, and the mapping between these models. An .edmx file also contains information that is used by the ADO.NET Entity Data Model Designer (Entity Designer) to render a model graphically. The recommended practice for creating an .edmx file is to use the Entity Data Model Wizard.
