Problem with WSDL being consumed by SOAP in VB.NET

Posted on 2014-12-03
Last Modified: 2016-03-02

I am working on a project that communicates with the Magento SOAP API v2.
We have been utilizing the API fine, however a new extension was installed on the Magento server which altered the WSDL we had previously consumed.  After the change, we successfully imported the new WSDL, though now it fails during initialization with the error message:

The XML element 'giftcardUpdateResponseParam' from namespace 'urn:Magento' references a method and a type.
Change the method's message name using WebMethodAttribute or change the type's root element using the XmlRootAttribute.

After googling for a bit, it seems this response is common if there are conflicts in the object names.  Reference:

The WSDL we are working with can be found here:

Can anyone help identify the problem and provide a solution so that this WSDL can be imported into VB.NET and the objects created in the reference.vb can be initiated properly?

Thank you.

can you post you code snippet, that is failing or write a test code to replicate it and post here?

First, I created a new windows form application and added a web reference with name magento19 using the URL of the WSDL.
This is the entire code needed to produce the error.
When the class that contains the line : Public Shared MagentoAPIConnection As New Magento19.MagentoService
is initialized, it throws the error.

Public Class Form1

    Public Shared MagentoAPIConnection As New Magento19.MagentoService
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load

        Catch ex As Exception

        End Try
    End Sub
End Class

The inner exception shows "Method MagentoService.giftcardSendEmail can not be reflected."

The inner-inner exception shows "The XML element 'giftcardUpdateResponseParam' from namespace 'urn:Magento' references a method and a type. Change the method's message name using WebMethodAttribute or change the type's root element using the XmlRootAttribute."

Can you use wsdl as  a service reference?

Thank you.  I did a bit of research on this before implementing the changes.  As you suspected, loading the wsdl as a Service Reference eliminated the issue.
