Remarks

Typically, the Action property is a URI indicating the intent of the SOAP request. However, the SOAP specification places no restrictions on the format and whether the URI refers to an existing document. The presence and content of the Action property can be used by Web servers such as firewalls to appropriately filter SOAP request messages in HTTP.

By default, the .NET Framework version 1.1 publishes the Action property in the soapAction attribute of the soap:operation element for each supported SOAP binding in WSDL documents generated for an XML Web service. The supported SOAP binding is SOAP 1.1.

For more information, see the SOAP specification on the W3C website.
