Overview of this book

The ADO.NET Entity Framework from Microsoft is a new ADO.NET development framework that provides a level of abstraction for data access strategies and solves the impedance mismatch issues that exist between different data models This book explores Microsoft’s Entity Framework and explains how it can used to build enterprise level applications. It will also teach you how you can work with RESTful Services and Google’s Protocol Buffers with Entity Framework and WCF. You will explore how to use Entity Framework with ASP.NET Web API and also how to consume the data exposed by Entity Framework from client applications of varying types, i.e., ASP.NET MVC, WPF and Silverlight. You will familiarize yourself with the new features and improvements introduced in Entity Framework including enhanced POCO support, template-based code generation, tooling consolidation and connection resiliency. By the end of the book, you will be able to successfully extend the new functionalities of Entity framework into your project.

Creating the EDM

Now that the Security database is ready, we will explore how we can create an EDM on top of the Security database.

Note that, before Entity Framework 7, there were two storage models—the EDMX file format based on XML schema or code. With Entity Framework 7, the EDMX file format will be dropped—we will have only the code-based format. Interestingly, this approach is also termed the "code-first only" approach.

You can create the Entity Data Model in one of two ways:

  • Use the ADO.NET Entity Data Model Designer
  • Use the command-line Entity Data Model Designer called EdmGen.exe

The first approach is preferred to the second. However, as we move through the chapters of the book, we will explore how we can follow the code-first approach to implement the model for our application that uses Entity Framework.

We will first take a look at how we can design an EDM using the ADO.NET Entity Data Model Designer.
