Get a thorough introduction to ADO.NET Entity Framework 4 -- Microsoft's core framework for modeling and interacting with data in .NET applications. The second edition of this acclaimed guide provides a hands-on tour of the framework latest version in Visual Studio 2010 and .NET Framework 4. Not only will you learn how to use EF4 in a variety of applications, you'll also gain a deep understanding of its architecture and APIs. Written by Julia Lerman, the leading independent authority on the framework, Programming Entity Framework covers it all -- from the Entity Data Model and Object Services to WCF Services, MVC Apps, and unit testing. This book highlights important changes for experienced developers familiar with the earlier version. * Understand the core concepts you need to make the best use of the EF4 in your applications * Learn to query your data, using either LINQ to Entities or Entity SQL * Create Windows Forms, WPF, ASP.NET Web Forms, and ASP.NET MVC applications * Build and consume WCF Services, WCF Data Services, and WCF RIA Services * Use Object Services to work directly with your entity objects * Create persistent ignorant entities, repositories, and write unit tests * Delve into model customization, relationship management, change tracking, data concurrency, and more * Get scores of reusable examples -- written in C# (with notes on Visual Basic syntax) -- that you can implement right away

This mini book will act as an extension to Programming Entity Framework 2nd Edition. Code First is an additional means of building a model to be used with the Entity Framework and is creating a lot of excitement in the .NET development community. The reader will begin with an overview of what Code First is, why it was created, how it fits into the Entity Framework and when to use it over the alternatives. Next the reader will gain an understanding of how Code First's built in conventions work and how to override them with configuration - whether they choose to use attribute based Data Annotations or strongly typed Fluent API configurations. The mini-book will then review the modeling possibilities of Code First, looking first at the impact of its conventions and then demonstrating how to override that behavior (and its impact on the database) first with the Annotations and then with the Fluent API. The book will also explore how Code First Database initialization works, the options it provides and how they impact your application development and database. Finally the reader will get a chance to see Code First in action in a small application.Because more complex application development with Code First will depend on an understanding of the DbContext API, which is the focus of Minibook #2, readers will see additional application scenarios with Code First in that following mini-book.
