Programming Entity Framework is a thorough introduction to Microsoft's core framework for modeling and interacting with data in .NET applications. This highly-acclaimed book not only gives experienced developers a hands-on tour of the ADO.NET Entity Framework (EF) and explains its use in a variety of applications, it also provides a deep understanding of its architecture and APIs. Although this book is based on the first version of Entity Framework, it will continue to be extremely valuable as you shift to the Entity Framework version in .NET Framework 4.0 and Visual Studio 2010. From the Entity Data Model (EDM) and Object Services to EntityClient and the Metadata Workspace, Programming Entity Framework covers it all. Author Julia Lerman, the leading independent authority on the framework, includes scores of reusable examples -- written in both Visual Basic and C# -- that you can implement right away. This book will help you :

• Understand the core concepts you need to make the best use of the Entity Framework (EF) in your applications

• Learn to query your data, using either LINQ to Entities or Entity SQL

• Create Windows Forms, WPF, and ASP.NET applications

• Build ASMX web services and WCF services

• Use Object Services to work directly with your entity objects

• Delve into model customization, relationship management, change tracking, data concurrency, and more

Presented in a clear narrative style that reflects the hundreds of hours the author has spent consulting, teaching, and writing about this new data access technology and testing its myriad features, Programming Entity Framework will help you master the technology and put it to work.

When I first saw this book I was put off by the sheer size of it, but when I started to dig in, I found that every page was full of information and was well organized. It is an easy read and easy to follow the code examples which can be had in both VB and C#. I was a bit worried when she mentioned that she was a VB developer, but she has not favored VB over C# which I appreciate.

Julia covers topics in fine detail where needed but skips the detail when unnecessary or not relevant (or simply says, "You learn more about that in chapter ...") which really helps comprehension. With a wide variety of topics ranging from "Querying entities" to "EF in WCF" it's hard to believe that she makes sure the reader understands what's going on at each turn, but Julia does it. Along the way you are given examples using both Linq to Entities and Entity SQL and she explains any caveats of using either.

Even though she did answer the question, "What is the difference between Linq to SQL and EF", I still find myself wanting more of an answer, but other than that this is a great book and I recommend it to anyone even if it's just as a reference.

I have hundreds of computer books on programming in the last 24 years. This is by without a doubt the best written, most informative on the subject matter of any book I ever purchased. Julia Lerman knows her subject matter and is able to pass her knowledge on without losing the reader along the way. O'Reilly needs to hear more from her! Great author and excellient work! I want to thank Julia Lerman for her time and attention to details she put into this effort! Thanks

This is a great book for both the beginner programmer willing to know about the EF and for the seasoned coder who wants the details of this new data access technology.
Sample code is available in both VB and C#, with good examples and techniques.

This book is absoluetely amazing.
If you don't know what you are talking after doing the hands on, on this book, then the book has done it's job
The first ten chapters are intro to advance ling sql entity framework-the author waste no time explaining the approach in lamens- this i liked alot me being a learner
I espectially liked the N-tier implementation towards the end of the book
The book has included some wcf and wpf implementations too- no chance of getting bored with this book
