More Effective C# 50 Specific Ways to Improve

"Shining a bright light into many of the dark corners of C# 3.0, this book not only covers the ls"how,rs" but also the ls"why,rs" arming the reader with many field-tested methods for wringing the most from the new language features, such as LINQ, generics, and multithreading. If you are serious about developing with the C# language, you need this book." Bill Craun, Principal Consultant, Ambassador Solutions, Inc. "More Effective C#is an opportunity to work beside Bill Wagner. Bill leverages his knowledge of C# and distills his expertise down to some very real advice about programming and designing applications that every serious Visual C# user should know.More Effective C#is one of those rare books that doesnrs"t just regurgitate syntax, but teaches youhowto use the C# language." Peter Ritchie, Microsoft MVP: Visual C# "More Effective C#is a great follow-up to Bill Wagnerrs"s previous book. The extensive C# 3.0 and LINQ coverage is extremely timely!" Tomas Restrepo, Microsoft MVP: Visual C++, .NET, and Biztalk Server "As one of the current designers of C#, it is rare that I learn something new about the language by reading a book.More Effective C#is a notable exception. Gently blending concrete code and deep insights, Bill Wagner frequently makes me look at C# in a fresh lightone that really makes it shine.More Effective C#is at the surface a collection of very useful guidelines. Look again. As you read through it, yours"ll find that you acquire more than just the individual pieces of advice; gradually yours"ll pick up on an approach to programming in C# that is thoughtful, beautiful, and deeply pleasant. While you can make your way willy-nilly through the individual guidelines, I do recommend reading the whole bookor at least not skipping over the chapter introductions before you dive into specific nuggets of advice. Therers"s perspective and insight to be found there that in itself can be an important guide and inspiration for your future adventures in C#." Mads Torgersen, Program Manager, Visual C#, Microsoft "Bill Wagner has written an excellent book outlining the best practices for developers who work with the C# language. By authoringMore Effective C#, he has again established himself as one of the most important voices in the C# community. Many of us already know how to use C#. What we need is advice on how to hone our skills so that we can become wiser programmers. There is no more sophisticated source of information on how to become a first-class C# developer than Bill Wagnerrs"s book. Bill is intelligent, thoughtful, experienced, and skillful. By applying the lessons from this book to your own code, you will find many ways to polish and improve the work that you produce." Charlie Calvert, Community Program Manager, Visual C#, Microsoft InMore Effective C#,Microsoft C# MVP and Regional Director Bill Wagner introduces fifty brand-new ways to write more efficient and more robust software. This all-new book follows the same format as Wagnerrs"s best-sellingEffective C#(Addison-Wesley, 2005), providing clear, practical explanations, expert tips, and plenty of realistic code examples. Wagner shows how to make the most of powerful innovations built into Microsoftrs"s new C# 3.0
