Examples

The following code example reads a discovery document from a file using the Read and writes it back out to file using the Write method.

Remarks

XML Web services discovery involves discovering the available XML Web services, given an URL. The URL typically points to a discovery document, which usually has a .disco file name extension. The discovery document, which is an XML document, contains references to information about the existence of XML Web services, such as a service description, XML Schema Definition (XSD) language schema, or another discovery document. This class represents the contents of the discovery document; where the References property contains a list of the references contained within the discovery document.
