Consuming OTRS TicketConnector from .NET apps

Question

I want to consume OTRS TicketConnector webservice in a .NET app.

Normally, the easiest way to get connected to a webservice is to import its WSDL via 'Add Service Reference'. Unfortunately, OTRS TicketConnector doesn't publish the WSDL.

I've found a custom WSDL for TicketConnector here. But when I'm trying to use it in 'Add Service Reference' it leads to an empty Reference.cs showing the following errors:

Cannot import wsdl:portType
Detail: An exception was thrown while running a WSDL import extension: System.ServiceModel.Description.XmlSerializerMessageContractImporter
Error: There was a problem loading the XSD documents provided: a reference to a schema type with name 'OTRS_TicketCreate' and namespace 'http://www.otrs.org/TicketConnector/' could not be resolved because the type definition could not be found in the schema for targetNamespace 'http://www.otrs.org/TicketConnector/'. Please check the XSD documents provided and try again.

Custom tool error: Failed to generate code for the service reference 'ServiceReference1'.  Please check other error and warning messages for details.

I've tried to import the WSDL above via svcutil with no success.
Also, I've tried to import this WSDL via 'Add Web Reference' with the same results.

So my question is: how do you consume OTRS TicketConnector service from a .NET app?
Maybe you can give a code snippet or a proper WSDL that can be successfully imported with the .NET tools?
Also, I would appreciate any help in resolving issues with the WSDL errors I mentioned above.

Thanks to the OTRS community forum, I've got the answer. WSDLs for Ticket Connector are available at GitHub.
