Examples

The following example demonstrates the use of the properties and methods exposed by the OperationBinding class. It takes an existing ServiceDescription and adds support for the SOAP protocol.

Remarks

The OperationBinding class corresponds to the Web Services Description Language (WSDL) <operation> element enclosed by the <binding> element, which in turn corresponds to the Binding class. For more information about WSDL, see the WSDL specification.
