I'm trying to add a Service Reference to my project and I'm getting constantly the same error.
I've created a mock service with SOAP UI that seems fine, then I try to add a service reference to this mock service and the error appears:
Warning 14 Custom tool warning: Cannot import wsdl:portType
Detail: An exception was thrown while running a WSDL import extension: System.ServiceModel.Description.DataContractSerializerMessageContractImporter
Error: Schema with target namespace 'urn:oasis:names:tc:dss:1.0:core:schema' could not be found.
XPath to Error Source: //wsdl:definitions[@targetNamespace='http://tempuri.org/esign']/wsdl:portType[@name='EsignServiceSoap11PortType']
The import on the wsdl where schema with namespace urn:oasis:names:tc:dss:1.0:core:schema is being loaded is:
<wsdl:types>
<schema xmlns="urn:oasis:names:tc:dss:1.0:core:schema">
<import namespace="urn:oasis:names:tc:dss:1.0:core:schema" schemaLocation="oasis-dss-core-schema-v1.0-os.xsd"/>
</schema>
.....
</wsdl:types>
I've already tried to link the schemaLocation directly to the file in the same folder than the wsdl, to a url where it's published in a private server and to a public uri where it's also published.
I get always the same error and I'm starting to feel that maybe I'm mistaken with the source of the problem.
Any insight will be much appreciated.
UPDATE: I've injected urn:oasis:names:tc:dss:1.0:core:schema complete definition inside my wsdl file, instead of trying to import it. When I do so, SOAP UI still creates correctly the mocking service, however, when I try to add a Service Reference, this error is thrown during service discovery:
The document was understood, but it could not be processed.
- The WSDL document contains links that could not be resolved.
- DTD is prohibited in this XML document.
Metadata contains a reference that cannot be resolved: 'http://elite8100-3:8088/mockEsignServiceSoap11Binding?WSDL'.
The content type text/html; charset=iso-8859-1 of the response message does not match the content type of the binding (application/soap+xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 455 bytes of the response were: '<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<soap:Body>
<soap:Fault>
<soap:Code>
<soap:Value>Server</soap:Value>
</soap:Code>
<soap:Reason>
<!--1 or more repetitions:-->
<soap:Text xml:lang="en">Missing operation for soapAction [null] and body element [null] with SOAP Version [SOAP 1.2]</soap:Text>
</soap:Reason>
</soap:Fault>
</soap:Body>
</soap:Envelope>'.
The remote server returned an error: (500) Internal Server Error.
If the service is defined in the current solution, try building the solution and adding the service reference again.
EDIT2: I've used Fiddler to check http traffic when trying to create the proxy, as suggested in the answer. During the creation, a 500 internal server error appears on Fiddler when trying to reach the mockService url, the response from the server was "Missing operation for soapAction [null] and body element [null] with SOAP version [SOAP 1.2]".
This is, currently, the WSDL I'm using to create the mockService.

I've downloaded every single .xsd associated and published them on a public server, also I've changed schemaLocations so they point to addresses on this public server, however, the problem seems to be related to WSDL structure.
