4.0 out of 5 stars
Very good book with a very bad index and no free PDF, April 16, 2008
This review is from: Pro LINQ: Language Integrated Query in C# 2008 (Expert's Voice in .NET) (Paperback)
Microsoft must be under new management, we are getting a slew of new, truly useful tools that are making pretty big strides forward for faster more enjoyable C# development and ease of maintenance. The latest technologies seem well worth taking the time to master. I find the combination of LINQ and the Sync framework couldn't have come at a better time. While the book mentions that LINQ to SQL only supports SQL Server, that is no longer true as you can also use (at least) MS SQL Server Compact Edition 3.5 (which is required for the Sync Framework). You can't use the visual object relational designer with SSCE but the book documents SQLMetal, and you can use that to create your context.
Overall I found this to be a very good book but it has a few flaws. If like me you are interested in LINQ for a current or upcoming database project here is what I would suggest. First don't start with this book, finish with it. Start with the ten excellent screencasts by Mike Taulty. Then read this book. Your reading will go much faster and you'll get a satisfyingly sated feeling. The author will probably hate me for saying this, but if you already know SQL or ADO.NET 2.0, I would suggest reading Chapters 1-3, then skim 4 and 5 just to get an overview of the operators available. Then read part 5 (Chapters 12-18) on LINQ to SQL. After you digest that I would suggest whichever topics interest you the most, then I would finish with a more thorough read of Chapters 4 and 5 on Deferred and Nondeffered operators, which in my mind are really a thoroughly documented reference section.
The reason the author will hate that, is he doesn't want readers to use LINQ for just database purposes, and he states that many times in the book. In fact, I think that is why he put the LINQ to SQL section at the end. However, he seems to have made a significant effort to make any part readable on its own, so I see no problem with skipping to the end so early.
The book doesn't really cover data binding, but there is a lot of good information on that available on the internet (the above mentioned screencasts show some of them, and an overly long video on Channel 9 with Young Joo from August 2007 shows even more).
I also have a few nit-picky things that drove me crazy. The most significant one being the amount of repetition and unedited console output. I was also none too happy that the author didn't mention that the Visual Studio Command prompt was under the START menu not an IDE menu. But then again without the author I wouldn't even have known there was a Visual Studio 2008 command prompt.
The weakest part of the book is the index, it is downright anemic. In the several weeks since I've finised the book the index has NEVER helped me find things I remember reading. If you find items of interest you better pencil them into the back cover if you want to find them again later. If one book ever needed a free PDF, this one is it, but they charge $10 for it. Maybe that is why they made the index so bad, to encourage you to fork over another $10.
That said, I also found a good half-dozen or so gems in the book that saved me significant time. Now I could tell you what those are but I think you should buy the book to find out.

LINQ: More than an ORM, January 7, 2008
This review is from: Pro LINQ: Language Integrated Query in C# 2008 (Expert's Voice in .NET) (Paperback)
When I first heard someone describe LINQ, I thought "Oh, another ORM... that doesn't sound very exciting".
Upon further research I discovered that LINQ is actually quite a bit more than just "another ORM", in fact, I would say it is one of the more interesting things from Microsoft lately.
The book Pro LINQ does a very good job of covering this new technology, and it does so in a way that you would expect for a "Professional" level book.
For example, I found it immediately appealing that Chapter 1 starts with a code example before ever getting to any regular text. The rest of the book follows suit. There are plenty of explanations, but sometimes seeing the code & result provides the clearest view.
The author does a good job of explaining the technology in detail, why it is useful, and very practical tips on how to make the most of it. The book covers using LINQ to query Objects, XML, DataSets and finally SQL.
I have used the book as an introduction to the topic, and for that it has done an excellent job. It appears that the book is comprehensive enough to also serve as a working reference book, but I have not personally had the chance to use it as such yet.

Code, Code, and then More Code... Excellent, December 31, 2007
This review is from: Pro LINQ: Language Integrated Query in C# 2008 (Expert's Voice in .NET) (Paperback)
This book claims to be about code, code, and then more code. I completely agree with the author's claim, it is code from front to back.
The book covers every feature of Linq in great detail, but one of my favorite parts of the book is chapter on the C# 3.0 Language features and other parts of the book that show how to take advantage of the Linq language features in everyday application code.
The author goes into great detail in every part of the of the book. The author also has a great companion site that is being updated with the latest new features coming out, like LINQ to XSD.
The accompanying code is very usable and well organized.
The only thing lacking would not be a legitimate complaint, since the authors claim code level detail and not architectural level guidance, but I will mention it anyway. I would have like to have seen more guidance on architecture and how Linq fits into the big picture. That is not covered, but like I said, they didn't claim to, so I can't ding them. The point of the comment.... 2nd edition ...hint, hint.....
If you want to get into the guts of Linq, this book is definitely for you. I highly recommend it for every .NET 3.5 programmer.
