The methods {0} and {1} use the same request element <{2} xmlns='{3}'>. When the RoutingStyle of the XML Web service is RequestElement, request elements must be unique across methods on the XML Web service. If you are using the Rpc style, you can change the message name with the RequestElementName and RequestElementNamespace parameters to SoapRpcMethodAttribute. For document style using wrapped parameter style, use the RequestElementName and RequestElementNamespace parameters to SoapDocumentMethodAttribute. For the bare parameter style, you must change the element that represents the parameter. Alternatively, you can specify a RoutingStyle of SoapAction on the XML Web service.
