Question : Error while importing web service

Hi all experts,

I have a problem with importing third-party web service to my .NET application. Framework version 2.0. When I'm adding a web reference, I'm getting following errors:

Custom tool error: Unable to import WebService/Schema. Unable to import binding 'IST_ExchWebServicebinding' from namespace 'http://tempuri.org/'. The operation 'TransferEMCOSData' on portType 'IST_ExchWebService' from namespace 'http://tempuri.org/' had the following syntax error: The operation has no matching binding. Check if the operation, input and output names in the Binding section match with the corresponding names in the PortType section.

WSDL file is attached (IP is masked by me)

Thank you in advance.

Answer : Error while importing web service

Hi all,

Finaly I found some solution. It is primitive, yet effective. I have obtained SOAP message from another client. Now I'm constructing raw SOAP message based on this example and sending it to web service. I will ask mods to accept my own answer as solution. Here's complete code:
