It is very readable and well organized. It is more than a collection of recipes because the first few chapters could give a beginner a good start on EF. Some people may think it has a lot of redundancy by providing a complete list of the code for each recipe, I personally like the completeness (I have the eBook version so the thickness does not bother me at all).
Here are my reservations:
1. There are three methods to query a conceptual model in EF - LINQ to Entities, Entity SQL, Query builder methods. This could be confusing to novice readers. The book mixes all of them and it may be the best approach to mix them to achieve the most elegant code, but I wish the author could share the rationale of each mixture which can be very educational.
2. Each recipe is a method to solve a problem with a specific approach but it may not be the best overall method. I wish the book could clearly point out this. A typical example is recipe 4-3 which is a method for assigning a value to a property with code during data saving. This is a very common scenario for data entry applications (e.g. setting the user ID value which is not entered by the user for each record) and it is usually achieved by a single line of code in an event handler of a control.Read more ›
the Kindle version is absolutely worthless and Amazon should return my money. there is so much necessary data on how to get from model creation to how to address the model in code that is missing that you cant use it.
Straight-forward in the beginning, Entity Framework can become complex quickly, as you begin implementing complicated business rules and processing operations.
Here, "Entity Framework 4.0 Recipes" is a life-safer as it provides you concise, easy-to-follow, step-by-step examples on resolving the wide variety of questions you could encounter.
Cleverly, the authors (Tenny and Hirani), invested considerable time monitoring the Entity Framework forums, identifying recurring questions and delivering thier problem-solving approach.
Bottom line: This book is "must-have" as it will save you hours of time and frustration researching solutions to the various questions you may encoutner when using Entity Framework. Do not start your project without it!
Couple this book with "Programming Entity Framework", by Julia Lerman, and you will have all the ammunition you need to successfully work Entity Framework.

I do share the criticism one other reader raised - that the common steps are repeated add nauseum, but in some ways I guess that is like any recipe book, so I suppose you could argue that's the way it should be done.
Until the updated Lerman book comes out(and perhaps beyond - it's hard to know), this book will be very useful to anyone diving into EF 4.0 development and will save you a lot of frustration.
While some comments noted that there is some confusion in presenting both a LINQ and Entity SQL solutions I suspect their intent was to provide solutions for those already familiar with LINQ as well as a solution in Entity SQL for those who have never been exposed to it. For those unfamiliar with either technique, I think the code speaks for itself: to me it's obvious that Entity SQL is simply more concise, "tighter" in terms of verbiage and clearer in its intent; more intuitive. Those more familiar with LINQ might disagree, but then, that's why the solutions are presented using both techniques: your choice. As for "confusing," or which one's "right," both work equally well, and are nicely contrasted with one another. I'd venture, however, that the MS future is evolving towards Entity SQL and away from LINQ; clearly that's where development is ongoing.Read more ›
