本书的作者，也是.NET专家Bill Wanger给出我们50条利用C#优点以及特性来写出健壮的，高效的，易于维护的代码的高效法则。同时，本书也反映出了C#语言愈发高级的特性以及关于它的开发社区。本书同时也给出了大量新颖的方法让你能够写出高效可靠的代码。*的第三版囊括了一些泛型和一些其他的语言集成查询（LINQ），还包括了对异常高级实践这一新的章节。 Bill Wagner是世界上最著名的C#开发者之一，是ECMA C#标准委员会的成员。他是Humanitarian Toolbox的主席，连续11年被授予Mcrosoft Regional Director和.NET MVP荣誉称号，最近刚刚被委派到.NET基础顾问理事会任职。
