Book 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.

Book rating: 5 Very helpful

We gave this to our son who is a very knowledgeable programmer. He says it has been very helpful and that he is learning a lot from it.

Book rating: 4 Light on LINQ to SQL

This book has very good coverage on LINQ to Object and LINQ to XML, but is light on LINQ to SQL.

If you need to use LINQ to SQL at your job, go for Pro LINQ from Apress. Beware the 2nd edition of Pro LINQ is coming out pretty soon.

PS. I am not in any way associated with Apress or the author of Pro LINQ.

Book rating: 4 LINQ in Action rocks

I was pleased with overall quality of this book. By and large this is the most comprehensive LINQ book currently available on the market. The writing style is easy to follow and the material is presented in logical manner. I rate it four instead of five because it follows a trend very common to books written by multiple authors - uneven quality of writing. LINQ to Objects for example is pure please to read, but I wish LINQ to SQL was covered better. Overall this is a solid book and I'd recommed it to any working developer.

Book rating: 5 A required desktop reference

I think the expression is "don't cry over spilled milk...", well when my son spilled milk on this book I almost cried. Why would you cry over a book you ask? There are many reasons. Not only does the book go into LINQ in depth (I know there is a C# in Depth book) but the authors cover all of the parts of the .NET framework that were created and needed for LINQ to function. In addition, all of the samples provided are both in C# and VB.NET. These samples are not your basic "Hello World" samples but useful reusable code snippets that get the point of the book section across.

The book starts of with an introduction to LINQ and the different versions of LINQ to xxx, more than enough to wet your whistle. The authors then go into the prerequisites of the .NET framework required, generics, anonymous types and lambda expressions. This chapter was so good I read it twice. The third chapter discusses how LINQ is made up. After this, the authors go in depth in describing the different types of LINQ, including LINQ to SQL, LINQ to Objects and LINQ to Amazon with useful examples.

This book will be a reference book on my book shelf. I expect to refer to this book constantly.

Book rating: 5 Great detail. Well organized and thorough.

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.
