Programming Entity Framework
Programming Entity Framework is nearly 800 pages packed full of everything there is to know about EF. The author leaves no stone unturned as she takes you from simplest concepts such as querying & databinding, to more advanced scenarios such as concurrency, N-Tier and using your own Entities with IPoco. The book is chalk full of informative diagrams and extensive code samples.
Some of the patterns used (or not used) in the book may not be my favorite, however, I don’t believe that is the focus of the author. You can certainly fit or visualize the examples into your codebase quite easily.
Given my nearly 2 years of experience in EF, I will tell I have not found a single source of Entity Framework information more complete than this book. I would recommend it to anyone who is beginning or considering a project using the Entity Framework.
