The Microsoft .NET Framework includes the Common Language Runtime (CLR) and a set of base classes that radically simplify the development of large-scale applications and services. This book examines the CLR in detail, so that you can put its new features to good use. The book also illustrates how language integration really works and guides you through component and enterprise development using the .NET Framework. In addition, it introduces you to four key .NET technologies: Data (ADO.NET) and XML, Web Services, Web Forms (ASP.NET), and Windows Forms. We used the latest release of Microsoft Visual Studio .NET and the .NET Framework SDK to prepare this manuscript and to develop all the examples and figures in this book. While we have done our best to ensure that the technical content of this book is up-to-date, it is possible that some items have changed slightly from the time of writing. To stay up-to-date, regularly check http://msdn.microsoft.com/net, http://www.gotdotnet.com/, and this book`s O`Reilly page, http://www.oreilly.com/catalog/dotnetfrmess2/. Audience While this book is for any person interested in learning about the Microsoft .NET Framework, it targets seasoned developers with experience in building Windows applications with Visual Studio 6 and the Visual Basic and Visual C++ languages. Java™ and C/C++ developers will also be well prepared for the material presented here. To gain the most from this book, you should have experience in object-oriented, component, enterprise, and web application development. COM programming experience is a plus. About This Book Based on a short course that Thuan has delivered to numerous companies since August 2000, this book is designed so that each chapter builds on knowledge from the previous one for those unfamiliar with each technology. To give you a heads-up, here are brief summaries for the chapters and appendixes covered in this book. Chapter 1 takes a brief look at Microsoft .NET and the Microsoft .NET Platform. It then describes the .NET Framework design goals and introduces you to the components of the .NET Framework. Chapter 2 lifts the hood and peers into the CLR. This chapter surveys the rich runtime of the CLR, as well as other features. Chapter 3 introduces you to .NET programming. You`ll examine a simple program that uses object-oriented and component-based concepts in four different languages: Managed C++, VB.NET, C#, and IL. You`ll also experience the benefits of language integration. Chapter 4 demonstrates the simplicity of component and enterprise development in .NET. Besides seeing component-deployment features, you`ll also examine complete programs that 1 ... - tailieumienphi.vn
