OperationBinding Class

Provides specifications for protocols and data formats for the messages used in the action supported by the XML Web service. This class cannot be inherited.

For a list of all members of this type, see OperationBinding Members.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

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 specification at http://www.w3.org/TR/wsdl/.

Example

[Visual Basic, C#, C++] 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.
