Covers C# 4 IN DEPTH SECOND EDITION Jon Skeet FOREWORD BY ERIC LIPPERT M A N N I N G Praise for the First Edition The best C# book available for intermediate to expert developers. Experienced .NET developers who think they know everything there is to know about the C# language will almost certainly learn more than a thing or two in this book. It is an interesting cover- to-cover read, and will be a handy desktop reference as well. I recommend this book to anyone who wants to become a C# expert. —Alvin Ashcraft, DZone review Simply put, C# in Depth is perhaps the best computer book I’ve read. —Craig Pelkie, Author, System iNetwork I have been developing in C# from the very beginning and this book had some nice sur- prises even for me. I was especially impressed with the excellent coverage of delegates, anonymous methods, covariance and contravariance. Even if you are a seasoned devel- oper, C# in Depth will teach you something new about the C# language... This book truly has depth that no other C# language book can touch. —Adam J.

I actually found it very easy to engage into the whole lambda expressions topic and really liked the chapter about lambda expressions. —Jose Rolando Guay Paz Web Developer, CSW Solutions This book wraps up the author’s great knowledge of the inner workings of C# and hands it over to readers in a well-written, concise, usable book. —Jim Holmes Author of Windows Developer Power Tools Every term is used appropriately and in the right context, every example is spot-on and contains the least amount of code that shows the full extent of the feature...this is a rare treat. —Franck Jeannin, Amazon UK reviewer If you have developed using C# for several years now, and would like to know the inter- nals, this book is absolutely right for you. —Golo Roden, Author, Speaker, and Trainer for .NET and related technologies More Praise for the First Edition If there’s one must-have book for .NET developers, this is it.
