Chapter 28. The System.Web.Services Namespace
The System.Web.Services namespace contains the types
used for creating web services. Web services are “component-like” units
of programming logic that exist on a web server as .asmx files.
Web services can be incorporated seamlessly into Windows or ASP.NET
applications. Web services differ from many other methods of remote
method invocation (like DCOM) in that they use open XML-based
standards, work over normal text HTTP channels, and can be consumed
(with a little more programming work) from applications on other
platforms and non-Windows operating systems.
The System.Web.Services namespace is the starting
point for creating web services. It contains a WebService class that custom
web services can inherit from and the WebMethodAttribute and WebServiceAttribute, which are
used to mark web service classes and methods and add additional
information. Most types in other web service namespaces are used
seamlessly by the .NET framework and are not used directly by the .NET
programmer.
Figure 28-1 shows the
types in this namespace.
