The purpose of this book is to explain how to develop applications and reusable classes for the .NET Framework. Specifically, this means that I intend to explain how the CLR works and the facilities that it offers. I’ll also discuss various parts of the Framework Class Library (FCL). No book could fully explain the FCL—it contains literally thousands of types now, and this number continues to grow at an alarming rate. Therefore, here I’m concentrating on the core types that every developer needs to be aware of. And although this book isn’t specifically about Windows Forms, Windows Presentation Foundation (WPF), Microsoft Silverlight, XML web services, Web Forms, Microsoft ASP.NET MVC, Windows Store Apps, and so on, the technologies presented in the book are applicable to all these application types.

英文版！ This is a book about computer organization and architecture. It focuses on the function and design of the various components necessary to process information digitally. We present computing systems as a series of layers, starting with low-level hardware and progressing to higher-level software, including assemblers and operating systems. These levels constitute a hierarchy of virtual machines. The study of computer organization focuses on this hierarchy and the issues involved with how we partition the levels and how each level is implemented. The study of computer architecture focuses on the interface between hardware and software, and emphasizes the structure and behavior of the system. The majority of information contained in this textbook is devoted to computer hardware, and computer organization and architecture, and their relationship to software performance.
