What started as a question about querying databases with familiar programming languages became John Paul Mueller's thorough introduction to LINQ and its integration with the .NET Framework. You’ll learn how to write queries across different data types—including objects, XML, and SQL Server—using a uniform language that works with Visual Basic and C#. Chapters cover LINQ providers, extension methods, lambda expressions, and practical examples like working with the Northwind database. This book suits developers new to LINQ who want to streamline data access and write concise, efficient code without juggling multiple query languages.

When Joe Mayo, a Microsoft MVP and seasoned software consultant, wrote this book, he aimed to bridge the gap between diverse data formats and LINQ programming. You’ll learn how to build advanced LINQ queries that integrate XML, SQL, ADO.NET, and unstructured data through practical examples like LINQ to Twitter. The book covers creating custom extension methods, managing multi-threaded applications with PLINQ, and even building your own LINQ provider, offering a deep dive into both theory and application. If you’re looking to master LINQ beyond basics and handle complex data scenarios, this book will expand your toolkit significantly, though it’s best suited for developers comfortable with C# and data manipulation.

This tailored book explores the essentials of LINQ with a focus on rapid progress through practical, step-by-step daily exercises. It covers core LINQ concepts, syntax variations, and real-world applications, all matched to your background and goals. By concentrating on your specific learning interests, this personalized guide reveals how to write efficient queries, manipulate data collections, and integrate LINQ seamlessly into your projects.
