Matthew MacDonald ist Programmierer und Buchautor. Er hat in unserer Missing Manual-Reihe Handbücher zu Excel, Access und zur Website-Entwicklung verfasst, außerdem ein gutes Dutzend Bücher über die .NET-Programmierung. Irgendwann davor hat er auch einmal Englische Literatur und Theoretische Physik studiert - daran kann er sich aber nur noch dunkel erinnern.

Web services are poised to become a key technology for a wide range of Internet-enabled applications, spanning everything from straight B2B systems to mobile devices and proprietary in-house software. While there are several tools and platforms that can be used for building web services, developers are finding a powerful tool in Microsoft's .NET Framework and Visual Studio .NET. Designed from scratch to support the development of web services, the .NET Framework simplifies the process. Programmers find that tasks that took an hour using the SOAP Toolkit take just minutes.

Programming .NET Web Services is a comprehensive tutorial that teaches you the skills needed to develop web services hosted on the .NET platform. Written for experienced programmers, this book takes you beyond the obvious functionality of ASP.NET or Visual Studio .NET to give you a solid foundation in the building blocks of web services, and leads you step-by-step through the process of creating your own.

Beginning with a close look at the underlying technologies of web services, including the benefits and limitations, Programming .NET Web Services discusses the unique features of the .NET Framework that make creating web services easier, including the Common Language Runtime (CLR) and the namespaces used in .NET programming. Filled with numerous code examples, the book leads you through some of the more challenging issues of web services development, including the use of proxies, marshalling of complex data types, state management, security, performance tuning and cross-platform implementation. The book also covers: - Creating and publishing your first web service - The UDDI project, tModels and what they mean for web service publishers - Securing web service applications

Written for programmers who are familiar with the .NET Framework and interested in building industrial-strength web services, Programming .NET Web Services is full of practical information and good old-fashioned advice.
