this wsdl contains many unresolved links. wsdl references resolve when change occurrences of b2borexatest orseviceb2btest. there total of 4 references b2borexatest in service url. doing so, able create proxy class using svcutil.

https://b2borexatest.oracleoutsourcing.com/soa-infra/services/default/mmissoaprequestreceiver!1.0/corerule220.wsdl   https://orserviceb2btest.oracleoutsourcing.com/soa-infra/services/default/mmissoaprequestreceiver!1.0/corerule220.wsdl 

this how these objects defined in wsdl

<types>-<xsd:schema xmlns="http://schemas.xmlsoap.org/wsdl/" targetnamespace="http://www.caqh.org/soap/wsdl/" elementformdefault="qualified"> <xsd:import schemalocation="https://b2borexatest.oracleoutsourcing.com:443/soa-infra/services/default/mmissoaprequestreceiver!1.0*soa_d48cf4e0-5e7b-43ad-b430-727180d48841/routeeditransactions_ep?xsd=xsd/corerule2.2.0.xsd" namespace="http://www.caqh.org/soap/wsdl/corerule2.2.0.xsd"/>     </xsd:schema>     </types>-<message name="realtimerequestmessage">     <part name="body" element="core-xsd:coreenveloperealtimerequest"/>     </message>     <message name="realtimeresponsemessage">     <part name="body" element="core-xsd:coreenveloperealtimeresponse"/>     </message> 

this how part of soap:body on fiddler request looks like

`<s:body xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xsd="http://www.w3.org/2001/xmlschema"> <coreenveloperealtimerequest xmlns="http://www.caqh.org/soap/wsdl/corerule2.2.0.xsd"> <payloadtype xmlns="">x12_270_request_005010x279a1</payloadtype> <processingmode xmlns="">realtime</processingmode><payloadid xmlns="">461726944</payloadid> <timestamp xmlns="">2013-07-23t07:35:22z</timestamp> <senderid xmlns="">sid</senderid> <receiverid xmlns="">rid</receiverid> <coreruleversion xmlns="">` 

response soap ui or fiddler. object of interest in corerealtimresponse. 1 null when using proxy call service method.

code:

 var orrealtimetrans = new ormcdproxy.coreenveloperealtimerequest()             {                 payloadtype = "x12_270_request_005010x279a1",                 processingmode = procmode,                 payloadid = interchangecontrolnumber,                 coreruleversion = ruleversion,                 senderid = senderid,                 receiverid = receiverid,                 timestamp = datetime.utcnow.tostring("yyyy-mm-ddthh:mm:22z"),                 payload = query270             };   ormcdproxy.coreenveloperealtimeresponse resp = ormcdproxy.realtimetransaction(orrealtimetrans); 

this resp object null.

http://webservices20.blogspot.com/2008/10/interoperability-gotcha-visual-studio.html documents problem , solution add web reference instead of service reference.

but not option me because service wsdl has unresolved links , have no control on it.
