Explanation

An .edmx file is an XML-based file that contains three sections: conceptual model (SSDL/CSDL definitions), storage model (database schema), and mapping specifications (MSL) between these models. Being an XML file allows it to be human-readable and editable while defining the complete Entity Data Model structure that Entity Framework uses.
