New features in Entity Framework 7
Entity Framework 7, a major redesign of the ORM, is the latest version of Entity 
Framework with the vision of "New Platforms, New Data Stores."
Some of the striking features of this release include support for the following:
• 
Non-relational data stores and in-memory data
: You can now use Entity 
Framework with NoSQL databases as well.
Entity Framework 7 now provides support for the following data providers:
°
SQL Server
°
SQLite
°
Azure Table Storage
°
Redis
°
In memory (for unit testing)
• 
Windows Phone and Windows Store applications and the Linux and 
Macintosh systems
: Entity Framework 7 now provides support for
Windows Phone, Windows Store, and ASP.NET 5 and desktop applications.
• 
Unit testing
: Entity Framework 7 now provides support to unit test your 
applications against in-memory or memory-resident databases.
Summary
Entity Framework mainly addressees how easily you can persist and query your 
data with many added services. You can use Entity Framework to focus on the 
object model rather than the logical model. In other words, you can add a level
of abstraction on top of your relational store.
In this chapter, we explored Entity Framework and the architectural components of 
Entity Framework, and provided a comparative analysis between Entity Framework 
and other ORM tools. In the next chapter, you will learn how to get started with 
Entity Framework.

Getting Started
In the previous chapter, we took a look at Entity Framework, including its 
architecture and its features. We also had a look at the new and enhanced
features in Entity Framework 7. Note that Entity Framework 6.0 ships with
Visual Studio 2013, but you can also install it via NuGet if needed. Also, Entity 
Framework 7 is yet to be released.
In this chapter, we will design our 
Security
database, create an Entity Data
Model (EDM) on top of it, and then use the EntityDataSource control to bind
data exposed by the EDM to a GridView control.
The DataSource controls are those that are used to connect to a data source and
then retrieve data from those data sources. If you use DataSource controls, the
need of writing tedious code to perform
