Problems consuming Zend-SOAP server in .Net client

I have written a Zend-SOAP server that uses AutoDiscover to generate the WSDL.
I cannot add this service to a .Net client that I’m building for testing.
Our customer calls our service and gets 500 errors but PHP is not logging them.

I used this tutorial to try to get it working but it still din’t work.

Has anyone successfully consumed a Zend-SOAP service using a .Net client and HOW?

There is very little on this anywhere on the web.

there is blog post in zend framework site that cover zend-soap usage

And that helps me how?

There’s a SO answer here:
