Product Description 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.
Who is this book for? This book is written for the proficient C# developer, but you do not need to be up on all the latest C# features to understand the material. When you finish this book, you will be up on all the latest C# features.
Featured Customer Reviews  Great Book!!!,
October 03, 2008Comprehensive and well explained,
September 25, 2008 After being disappointed by other books on ASP.NET was leery in purchasing another. Wishing to learn about LINQ I finally gave in and ordered this one. I'm pleasantly surprised and delighted that it actually teaches you something other than just touting the benefits versus older technology. It is so complete as opposed to other books that give you a dip in the shallow end and leave you to wonder what else there is out there.
Excellent book. Well worth the price. Get it.Learn LINQ = Buy this book,
August 08, 2008 I am always looking for new tools to make my job as a developer easier, more efficient, allow me to write code that is more easily maintained and just make things more exciting. The problem that comes with learning these new tools (such as LINQ) is finding the time to learn them to the point that they are useful. This style of this book made it very easy to read with excellent code examples, providing me with the knowledge to get started using LINQ in my current project within a week of reading. Lastly, I was able to contact the author (with a timely response) about a question I had using LINQ in my project. Joe was friendly in his response and very approachable. Highly recommended!Great book, great Kindle conversion,
August 08, 2008 This is a very comprehensive and well structured LINQ learning guide. It can be used as a structured tutorial or as a reference guide, as definitions and sample code for each method call are complete.
What is really nice is that this book works well in eBook (Kindle) format. I am usually reluctant to buy technical books with code listings for the Kindle, but all the listings in the text are zoomable images and easy to read in the landscape rendition.Bought three books on LINQ -this one is the best!,
August 06, 2008 I'm an intermediate level C# programmer (I think) and have been using ADO.net with SQL-Server to build a database application for a client. When I read about LINQ earlier this year, it sounded like something too good to be true. I started with a couple of other books, but found practical explanations of getting things to work lacking. I get the impression, the authors are too far advanced and just assume we have fairly expert knowledge of some of the nuts and bolts things that are elementary to them, so they don't explain these things.
Joseph Rattz's book does not assume we know how to do a lot of this stuff. Rather he explains in detail, how to get LINQ up and running, and to actually get a query completed. I was able within an hour to run SQL Metal to generate an entity class (basically a map from SQL Server to corresponding data objects), and run some of the example queries in the book. That said, this is not a lightweight book for someone new to programming. It's just that he does an excellent job explaining a complex subject. It gets into advanced topics on LINQ and requires some knowledge of C#. If you plan to use this to work with SQL Server, you should also have some experience with that also.
Summing up, there is just something about Mr. Rattz's writing style that makes this book easy to read and understand. I find I'm actually enjoying reading this book, and I certainly can't say that about most technical books I study.
