Represents a reference to a metadata document returned from a metadata exchange endpoint.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
When using Windows Communication Foundation (WCF), a metadata endpoint can be created for any service. The endpoint can be queried for metadata that allows a client to communicate with the endpoint. For example, a metadata endpoint can return a Web Services Description Language (WSDL) document that describes the methods and data types of a service.
The class is used with WS-MetadataExchange responses where references are directly encoded as <mex:MetadataReference> or <mex:MetadataLocation>.
Metadata documents can reference many other documents that describe types and those documents can contain even more references. The class represents a single endpoint that returns a document that can itself contain multiple WSDL or XSD items as well as other metadata references to other WS-MetadataExchange endpoints.
Instances of the class are commonly used when processing a MetadataSet, which represents the total metadata exchange point. The MetadataResolver class is designed to resolve all references used to return the metadata. If, however, you need to examine each reference, use the class to represent each endpoint.
WCF implements the Web Services Metadata Exchange (WS-MetadataExchange) specification for returning metadata. That specification further uses the Web Services Transfer (WS-Transfer) specification to define the mechanism for retrieving XML-based data.
