Programming Entity Framework [Paperback]

This is definitely the book to have by your side if you are programming with the ADO.NET Entity Framework 1.0.

The author touches on a ton of subjects that include: Data Binding with Windows Forms and WPF Applications, Using Stored Procedures with the EDM, LINQ to Entities Queries, Customizing Entities, Using the ASP.NET EntityDataSource Control, Using Entities with Web and WCF Services, Using the Entity Framework in n-Tier ASP.NET Applications and n-Tier Client-Side Applications, Handling Entity Framework Exceptions, Performance, Security, Multithreaded Applications, and much more.

There is a lot covered in this book. One of the coolest things about this book is the amount of new possibilities it introduces. Many which I would not have considered without seeing them in this book.

I also like that the book covers the architectural aspects of integrating EF into several different types of architectures.

The author drills into each subject enough to get a thorough understand. With all the material covered, that is rare, but the book is an 800 page whopper.

I have been working with the EF 1.0 since its release in August and can say that this book has more information jammed into it than all the other resources I have been using combined.

The book includes VB.NET and C# code examples.

The book has a support site (google for learnentityframework) with the code samples and the database scripts available. The downloaded code is also in both VB.NET and C#. It is well organized and very usable.

The book is very well organized and is a good read. The author has a good writing style.

All in all, I do not think you can do without this book if you are going to do anything besides play around with the Entity Framework.

Over the past 20 years of my career as a software developer, application architects have recommended that enterprise applications be developed using multiple tiers to separate the concerns of the user interface, business logic and data access layers. The challenge for programmers has been to determine how one would actually build and maintain such a beast. Microsoft has addressed part of the data portion of this architecture recommendation by introducing the "Entity Framework" (EF) to the .Net technology stack.

In most cases, databases are designed for the database administrator and not the application developer. The EF allows a programmer to add an Entity Data Model (EDM) to a client application. With an EDM, programmers can create application centric object interfaces to their data sources without having to concern themselves with the nuances of the underlying data structures. The EF takes care of translating these application objects to the SQL statements that interact with the database. So, what will lead us on this journey?

The "Programming Entity Framework" book can be divided into two major sections. Chapters 1-14 provides an introduction to all the major EF concepts while Chapters 15-23 covers advanced topics. There is a website at http://learnentityframework.com/learnentityframework/ that supports the book and allows you to download database scripts and sample applications. (As a side note, I learned from this site that the author has agreed to update her book to cover changes introduced in the 2010 version of Visual Studio.)

I like the fact that Ms. Lerman provides both VB and C# code side by side with all of her examples (my personal goal is to become fluent in both languages). The book is peppered with side notes (designated by three paw prints) that make some clarification or add pertinent information to the page.

I did a search of alternative books that cover this same subject. I investigated the online information provided by Microsoft. None of the books I researched (as well as the Microsoft articles online) came close to the scope and readability of this book. Lerman does a great job of balancing her independent point of view on this subject with the insider tips and information that make for a good read.

The myriad of tools and components contained in the EF are now a strategic part of Microsoft's data access strategy going forward. So don't get left behind. I recommend "Programming Entity Framework" as your train to the data access future. I guess that would make Julia Lerman your Conductor and Engineer on this trip as well ... ;-).

I'm a seasoned VB6/PHP/Green Screen developer who has floated around .NET but never gone beyond tinkering. Entity Framework (and LINQ and MVC) have convinced me that it's time to jump fully on the .NET wagon.

I'm loving this book because while it assumes the reader knows how to write a program, it doesn't assume that the reader is a .NET programmer. It explains Entity Framework excellently while also explaining Visual Studio/.NET concepts succinctly, without wasting the reader's time explaining what an integer is.

The many pointers to web resources for further information are greatly appreciated and increase the book's value to someone, like me, coming to .NET rather late in the game without bogging down the book for seasoned .NET programmers.

Finally, the author's use of a "brown field" application for the examples, complete with "legacy typos" and examples of how EF can free you of legacy design flaws while leaving the legacy intact show that the author has been in the trenches writing real code and has a great deal of wisdom beyond Entity Framework to share.
