Full Description
Most books on Web Services have focused on specific technologies, and how to use those class libraries to build services and clients. Some have attempted to give an overview of SOAP and WSDL and other related technologies. This book will address the issue of why Web services exist, and how to create them using Microsoft .NET. As Program Manager for Web Services in Microsoft's .NET Framework group no one is in a better position than Keith to explain why .NET's web services tools were set up the way they are, and how to get the most out of them. Once you understand how implementation and architecture of Web services work in .NET, you'll be better able to take full advantage of .NET's powerful tools. The book features a lot of code and many working examples.
