SOAP: .Net client and PHP server - WSDL format problems

[gcornelisse]

I have a client that uses .Net and we want to setup SOAP services to integrate to our PHP application.  I've done this many times between PHP-to-PHP.  However, the .Net SOAP client is complaining about the WSDL format, which happens to work for fine in testing with a PHP SOAP client.  Here is the error from .Net:

 

Microsoft (R) Web Services Description Language Utility
[Microsoft (R) .NET Framework, Version 2.0.50727.42]
Copyright (C) Microsoft Corporation. All rights reserved.
Warning: This web reference does not conform to WS-I Basic Profile v1.1.
SOAP 1.1 binding was not found: WS-I's Basic Profile 1.1 consists of implementation 
guidelines that recommend how a set of core Web services specifications should 
be used together to develop interoperable Web services. For the 1.1 Profile,
those specifications are SOAP 1.1, WSDL 1.1, UDDI 2.0, XML 1.0 and XML Schema.

 

I downloaded Altova XML Spy and tried to tweak the format, but that only gave us more errors.  To be honest, I'm not super comfortable with WSDL syntax.  Is there an easier way to get the right WSDL format?
