10.4 Summary

• The W3C defines a “Web service” as “a software system designed to support interoperable
machine-to-machine interaction over a network.
• The infrastructure for XML Web services is built to conform to industry standards such
as SOAP, XML, and WSDL, and this allows clients from other platforms to interoperate
with XML Web services.

• When you build an XML Web service using ASP.NET, it automatically supports clients
communicating using the SOAP, HTTP-GET, and HTTP-POST protocols.
• Web services are distributed application components that are externally available. You
can use them to integrate computer applications that are written in different languages
and run on different platforms.
