VB.NET & SOAP - More than one endpoint configuration for that contract was found

Question

I am trying to call the webservice that can be seen at: http://www.flexiblecarhire.com/flexibleservice/fchxmlinterface.asmx?op=GetAirportLocations

I am using VB.net, but any solution in C# will be very welcome.

The way I am doing it is:

1. I am adding a new Service Reference to http://www.flexiblecarhire.com/flexibleservice/fchxmlinterface.asmx and selecting fchXMLInterface > fchXMLInterfaceHttpPost

2. In my code I have: Dim API As New ServiceReference1.fchXMLInterfaceSoapClient

When I run that, I am having an error message saying that:

An endpoint configuration section for contract 'ServiceReference1.fchXMLInterfaceSoap' could not be loaded because more than one endpoint configuration for that contract was found. Please indicate the preferred endpoint configuration section by name.

I checked the help at the first link I posted here and I could not find that. How can I fix that?

If I can't call this webservice as ServiceReference, how can I call this webservice?

Solution 1

Below are the steps i did try with the above web service and got back an invalid agentcode/password error message:

Click on Add web reference and add the URL and i have named it "CarHireRef" as the reference name and clicked OK.

Now my code to call a service looks as shown:

CarHireRef.fchXMLInterface ob = new CarHireRef.fchXMLInterface();
CarHireRef.ResultsGetLocations result = ob.GetAirportLocations("", "");

The above procedure does not have any config entry as i am adding a web reference and not a service reference.

Solution 2

It has created configuration provided below when I added service reference. There you can see two endpoints for the same contact.
You should either specify endpoint name what you are going to use like

var a = new ServiceReference1.fchXMLInterfaceSoapClient("fchXMLInterfaceSoap12");

or just remove unneeded endpoint configuration.
