This appendix will provide you with a high-level overview of the assemblies and namespaces of the Entity Framework. You will learn about the files that are used for the Entity Framework and the namespaces of the Entity Framework and their purpose.
You’ll find the physical DLL files that contain the Entity Framework APIs in the following directory:
<system drive>:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0, which contains:
This file contains functionality related to the design tools, such as the Designer, the mapping details, and the model viewer.
This file is the root of the Entity Framework. It contains all of the namespaces and classes for programming against the Entity Data Model (EDM).
The Entity Framework lives within the
System.Data namespace of the .NET Framework.
New functionality (classes, properties, and methods) has been added to
existing namespaces in the
System.Data hierarchy, along with a number of
new namespaces that begin with the term
System.Data.Entity. The System.Data.Entity.dll assembly provides all
of the namespaces, as shown in Figure A-1.
