XML Web Services to be found in .NET use Extensible Markup Language (XML) messages that follow the SOAP standard and have been popular with traditional enterprises. In such systems, there is often a machine-readable description of the operations offered by the service written in the Web Services Description Language (WSDL). The latter is not a requirement of a SOAP endpoint, but it is a prerequisite for automated client-side code generation in many Java and .NET SOAP frameworks.

The Web Services Description Language tool generates code for XML Web services and XML Web service clients from WSDL contract files, XSD schemas, and .discomap discovery documents. A .wsdl file is an XML document written in an XML grammar called Web Services Description Language (WSDL). This file defines how an XML Web service behaves and instructs clients as to how to interact with the service.
