Editorial Review:
LINQ is the project name for a set of extensions to the .NET Framework that provide a generic approach to querying data from different data sources. LINQ will premier in Visual Studio 2008, and will become the next must–have skill for .NET developers. For more information about LINQ, you can check out the author’s portal at www.linqdev.com. Pro LINQ: Language Integrated Query in C# 2008 is all about code. Literally, this book starts with code and ends with code. In most books, the author shows the simplest example demonstrating how to use a method, but they so rarely show how to use the more complex prototypes. Pro LINQ: Language Integrated Query in C# 2008 is different. Demonstrating the overwhelming majority of LINQ operators and protoypes, it is a veritable treasury of LINQ examples. Rather than obscure the relevant LINQ principles in code examples by focusing on a demonstration application you have no interest in writing, Pro LINQ: Language Integrated Query in C# 2008 cuts right to the chase of each LINQ operator, method, or class. However, where complexity is necessary to truly demonstrate an issue, the examples are right there in the thick of it. For example, code samples demonstrating how to handle concurrency conflicts actually create concurrency conflicts so you can step through the code and see them unfold. Most books tell you about the simple stuff, while few books warn you of the pitfalls. Where Pro LINQ: Language Integrated Query in C# 2008 returns your investment is in the hours, and sometimes days, spent by the author determining why something may not work as expected. Sometimes this results in an innocent looking paragraph that may take you a minute to read and understand, but took days to research and explain. Face it, most technical books while informative, are dull. LINQ need not be dull. Written with a sense of humor, Pro LINQ: Language Integrated Query in C# 2008 will attempt to entertain you on your journey through the wonderland of LINQ and C# 2008. What you’ll learn - How to leverage all the new LINQ relevant C# 2008 language features including extension methods, lambda expressions, anonymous data types, and partial methods.
- How to use LINQ to Objects to query in–memory data collections such as arrays, ArrayLists, and Lists to retrieve the data you want.
- Why some queries are deferred, how a deferred query can bite you, and how you can make deferred queries work for you.
- How to use LINQ to XML to revolutionize your creation, manipulation, and searching of XML data.
- How to query DataSets with LINQ to DataSet so you can co–exist with legacy code and use LINQ to query databases other than SQL Server.
- How to query Databases with LINQ to SQL, write your own entity classes, and understand how to handle concurrency conflicts.

Very Impressed 2008-07-04
I actually met Joe in a Books-A-Million in Montgomery, Alabama... He is a very nice guy too! The book is chock full of code, it is concise and it is worth every penny and then some. If you want to learn about how to use LINQ effectively, congratulations, you just found your book.
Excellent LINQ Resource 2008-07-02
Once I had heard of LINQ I had spent a lot of time reading through the MSDN docs, but I wanted more information about it. Pro LINQ was the answer. It gave a very thorough run-down of each of the various technologies involved with LINQ as well as a breadth of useful examples to illustrate the points that were made. In addition I thought that the book had a nice progression of topics that left you wanting to continue on to the next chapter. LINQ is an awesome technology, and I feel that this book is a great tool to add to your arsenal to help better utilize it to its fullest capabilities. This book was definitely written from a developer's standpoint, but I didn't feel that it threw too much at you. I would highly recommend this book.
Best book to learn LinQ and new C# 3.0 features 2008-06-01
This book is incredible at explaining the new LinQ functionality and since many of the enhancements made to C# were made to accomadate LinQ, it also does an excellent job at explaining the new language enhancements in a concise fashion. Highly recommend this book.
Outstanding 2008-05-30
It's very rare to find a book on any programming topic that works as both an introduction to the subject as well as a reference for seasoned users. Joseph Rattz's book should be the first stop for anyone hoping to learn about LINQ. The examples given make what could have been a potentially massive learning curve even for experienced ADO.Net users a lot smoother.
Good book - but XML heavy  2008-05-25
Reading this book you can get the illusion that LINQ is just about XML. There is so much more - pretend that LINQ has noting to do with XML and see how it can change your project delivery!
LINQ in Action This is the book that really shows what LINQ can do. It is VERY easy to read and get upto speed using this book - its a must have. Once you have mastered this book then look at others.
