The abstract ProtocolReflector class and its concrete derived classes create ServiceDescription objects from classes that are identified as Web services with the WebServiceAttribute attribute. Each concrete ProtocolReflector-derived class generates ServiceDescription objects according to a specified communication protocol; ProtocolReflector provides common functionality regardless of the protocol.

An output ServiceDescription instance can be used to generate a Web Services Description Language (WSDL) document with the Write method or one of the available overloads. The ServiceDescription instance can also be used by the ServiceDescriptionImporter class and related classes to generate client proxy code or abstract server code.

The ProtocolReflector class uses the WebServiceBindingAttribute to create a ServiceDescription for each binding it identifies in the Web service class. If that attribute is not present, the ProtocolReflector class creates a single binding for the entire class. For each Web service method (a method in the Web service class appearing with the WebMethodAttribute) belonging to a binding, a class derived from ProtocolReflector generates an operation and associated messages that are added to the ServiceDescription object.

Typically, a developer uses these classes indirectly through the ServiceDescriptionReflector class, instead of directly invoking classes derived from ProtocolReflector.
