LINQ for Visual C# 2005
Dear Reader,
Are you ready for the future of data access in .NET?
At the Microsoft Professional Developers Conference (PDC) 2005, Microsoft previewed a
new technology, Language-Integrated Query (LINQ). It captured a lot of attention because it
addressed the fundamental issue of merging object-oriented applications with relational data.
The LINQ Project team demonstrated how to use LINQ to query a variety of data sources, such
as a SQL Server database, an XML file, and an array, and how to manage the data using an
object-oriented approach.
I fell in love at first sight. I started to study LINQ closely, analyzing the source code pro-
vided on the conference's DVD and writing a lot of code myself. When the LINQ May 2006
Community Technology Preview (CTP) was released and I saw how mature and stable LINQ
had become, I decided to write this book. I read the official documentation and found it really
well done, but the enormous amount of information was split across too many documents. I
thought it would be useful to have a single text combining the essential LINQ concepts with
practical examples.
And that's what I wrote: a comprehensive guide to the three main parts of the LINQ May
2006 CTP: managing in-memory data (LINQ to Objects), accessing relational databases (LINQ
to ADO.NET), and manipulating XML documents (LINQ to XML). Each chapter offers many
practical examples that you can try yourself with the downloadable source code. My goal is
that you'll quickly learn everything you want and need to know about LINQ by actually
using LINQ.
I hope you'll enjoy my book and that it will make you as enthusiastic about LINQ as I am
while we wait for its formal release. The future of .NET data access is already here––and it's a
very bright one!
Ciao,
Fabio Claudio Ferracchiati
