I recently read through a new book covering the Entity Framework version 4.1 called Entity Framework 4.1: Expert’s Cookbook by my friend Tim Rayburn and Devlin Liles. The book is more of a guide through EF and expects the reader to have some knowledge of EF to begin. Having quite a bit of EF knowledge I found the book to give advanced .NET developers quite a bit of insight into the great data framework from Microsoft.
The book is very well written and I really enjoyed how it walked the reader/developer to all of the needed information to get started and then progressed through implementing the solution, explained how this solution works and finally talked about testing the solution for such things as performance. The authors have done a great job laying out the book so a reader can find the specific topic or recipe they need to dig into or else read the book from the start and progress through the Entity Framework with their expert guidance.
I recommend this book to everyone that needs to have another good EF reference guide at their fingertips.
