Chapter 5. XML Web Services (RPC the Easy Way)

XML Web services are, depending on your point of view, a breath of fresh air after the complexities of Microsoft .NET Remoting or a simplified approach to distributed code execution that lacks a few key features. Both arguments contain at least a grain of truth. More accurately, XML Web services represent a new approach to distributed architecture, one that favors simplicity, best design practices, and cross-platform use over raw communication speed. XML Web services provide a simple, robust, and flexible way to make a remote procedure call (RPC).

Most introductory .NET books provide a brief introduction to XML Web services and describe some of the underlying standards such as WSDL and SOAP. This chapter ...
