Product Description
LLINQ, Language INtegrated Query, is a new extension to the Visual Basic and C# programming languages designed to simplify data queries and database interaction. It addreses O/R mapping issues by making query operations like SQL statements part of the programming language. It also offers built-in support for querying in-memory collections like arrays or lists, XML, DataSets, and relational databases. LINQ in Action is a fast-paced, comprehensive tutorial for professional developers. This book explores what can be done with LINQ, shows how it works in an application, and addresses the emerging best practices. It presents the general purpose query facilities offered by LINQ in the upcoming C# 3.0 and VB.NET 9.0 languages. A running example introduces basic LINQ concepts. You'll then learn to query unstructured data using LINQ to XML and relational data with LINQ to SQL. Finally, you'll see how to extend LINQ for custom applications. LINQ in Action will guide you along as you explore this new world of lambda expressions, query operators, and expression trees. As well, you'll explore the new features of C# 3.0, VB.NET 9.0. The book is very practical, anchoring each new idea with running code. Whether you want to use LINQ to query objects, XML documents, or relational databases, you will find all the information you need to get started But LINQ in Action does not stop at the basic code. This book also shows you how LINQ can be used for advanced processing of data, including coverage of LINQ's extensibility, which allows querying more data sources than those supported by default. All code samples are built on a concrete business case. The running example, LinqBooks, is a personal book cataloging system that shows you how to create LINQ applications with Visual Studio 2008.

 Stutters onthe most important area August 26, 2008
Most of the reviewers have given high marks for this book. No issue with that, as long as the first six chapters of this book are concerned. It gives the best intrduction on subjects such as lambda expression and various Linq syntaxes. But the most important chapters should have been those dealing with Linq in N-tier architecture - chapters 7 and 8. But those were written in such a confusing manner that, at the end of those two chapters, you are left wondering why you spent money and time on this book. It is a pitty that almost all internet articles, including those on MSDN, deal with Linq as if it is an add-on to Microsoft Access programming and show pages and pages of "drag-and-drop and voila it works great!!" approach. I don't think anyone could write a successfull n-tier Linq code with that approach. Although this book goes little further than the drag-and-drop gimmic, it could have avoided so much fluff and concentrated just on what is needed for a real world n-tier programming using Linq. But unfortunately I don't know whether there is any better book treating Linq as a serious enterprise development tool.
 Comprehensible Tutorial August 8, 2008
This book is a well-written tutorial that is generally easy to understand. The logic is straightforward and the language is much better than in most of the other books I have been studying on ASP.NET 3.5 and C#. My only complaint is that I would have liked to see more depth in some sections. To fill in some of the gaps I have found "C# 3.0 in a Nutshell," from O'Reilly Media, to be very helpful, but I wouldn't consider it a replacement for this book. There is an online forum that goes with "LINQ in Action," and two of the authors and some other contributors are very responsive to questions. There are also some files of source code that can be downloaded from the Internet.
Great detail. Well organized and thorough. August 8, 2008

This was one of the best technical books I've ever read. It was easy to follow and understand. The examples were very clear and the section on the new features of VB and C# were wonderful and needed in order to understand the rest of the book.
I was slightly disappointed that most of the examples in the book were printed in C# instead of VB. BUT, I downloaded all the example projects and utilities and those are excellent! ALL of the examples are available in C# and VB. They are correct and a great on-the-go blueprint for my routines.
It was also very nice that they talk about (in easy-to-understand terms) the performance implications of different implementations.
The cover is a bit dorky, but you shouldn't judge a book by its cover!
A great buy for the novice LINQ programmer.
Great Tutorial on LINQ August 8, 2008

The book covers a lot of topics that emcompass LINQ including LINQ basics, but also LINQ to SQL, LINQ to XML. I like that it starts out with a discussion of the problem and doesn't dive directly into the solution. In addition, I think it teaches the technology without resorting to starting with database applications as the example. Anyone who has heard me talk about LINQ knows that I can't stand that LINQ to SQL is the wrong way to teach it to new people...they didn't fall into that trap.
In addition, I really like that there are lots of good examples and a great index. There was never an example I was looking for that the index didn't help me find. That's becoming rarer in books. I really liked their coverage of LINQ from both the consumer of LINQ and the provider of LINQ. Their discussion of the LINQ to Amazon provider provided quite a lot of good insight into how the inner workings of LINQ are put together.
My only hesitation at completely loving this book is that all the examples are either in C# or VB. This lends the book to feel a bit schizophrenic. I would have preferred a more bloated book where all the example in print were in both languages. This is especially true of LINQ because the language integration of LINQ is very dissimilar between the languages.
Overall, I would recommend the book to anyone trying to learn LINQ as a technology.
An important book, on an important topic June 29, 2008

LINQ in Action, at 600 pages provides a substantial introduction and in-depth discussion of LINQ, its history, its impact, and most important - its syntax and features. I found this book easy to navigate, given that many developers (I know I do) moved between LINQ to Objects, LINQ to XML and LINQ to SQL througout the working day. When you stumble over a particular query, I found it easy to find a relavent sample in the index.
If you haven't had an opportunity to move into the .NET 3.5 Framework world and use C# .0 or VB 0 syntax yet, then this book will arm you with the background necessary to move productively into the new 'Query Centric' programming paradigm - one free of complex 'for' loops and deeply nested 'if' statements (and free of embedded SQL string statements).
Although hefty in size, I recommend this book if you seriously want to move beyond the basics and really understand how to use LINQ.
