And once you begin to apply LINQ, the book serves as an on-the-job reference when you need immediate reminders.All the examples in the LINQ Pocket Reference are preloaded into LINQPad, the highly praised utility that lets you work with LINQ interactively. Created by the authors and free to download, LINQPad will not only help you learn LINQ, it will have you thinking in LINQ.This reference explains:LINQ's key concepts, such as deferred execution, iterator chaining, and type inference in lambda expressionsThe differences between local and interpreted queriesC# 3.0's query syntax in detail-including multiple generators, joining, grouping, query continuations, and moreQuery syntax versus lambda syntax, and mixed syntax queries Composition and projection strategies for complex queriesAll of LINQ's 40-plus query operatorsHow to write efficient LINQ to SQL queriesHow to build expression trees from scratchAll of LINQ to XML's types and their advanced useLINQ promises to be the locus of a thriving ecosystem for many years to come. This small book gives you a huge head start."e;The authors built a tool (LINQPad) that lets you experiment with LINQ interactively in a way that the designers of LINQ themselves don't support, and the tool has all kinds of wonderful features that LINQ, SQL and Regular Expression programmers alike will want to use regularly long after they've read the book."e;-Chris Sells, Connected Systems Program Manager, Microsoft

Rezensionen

"Kein langes Herumreden um den heißen Brei, Fokus auf Verstehen der Technologie durch Beispiele, Hinweise was wo wie diffizil anders läuft (z.B. lambda queries vs. comprehension syntax), Praxistips, Hinweise wo man Performance liegen lassen kann, kurz gesagt: es ist geschrieben für Entwickler mit Background.[...]Definitiv ein praktischer Begleiter im täglichen Einsatz [...]" -- glengamoi.com, Dezember 2008
