Null object from valid response - Namespace issue?

[Pathogenix]

Greetings,

I'm trying to fix a web service client which has been implemented in a
dailywtf worthy manner. I've decided to rip all the old code
out and start again from the proxy generated by wsdl.exe. I've
immediately run up against the same problem that spawned the original,
deeply fascinating code.

I can make a request, and Fiddler shows that the service is returning
a valid response, but the client is returning a null object. Browsing
the newsgroups suggests that this is a namespace issue, but I'm too
much of a humble n00b to know what I'm looking for. Below is my
response and the classes and methods which are involved. Can anyone
offer any hints on where to start bugfixing?

The problem might be with UNQualified Namespace attribute value.
Make sure the client sets namespace attribute as Qualified.
You can also modify WSDL and add the attribute value.

Cheers for the response, but I'm embarassed to say that I have no idea
how to implement your suggestions.

Forgive my ignorance, but in my WSDL I've got the following:

<types>
<xs:schema elementFormDefault="qualified"
targetNamespace="urn:enquiry">
<snip />
</xs:schema>
</types>

Shouldn't that make the attributes qualified by default? If not, how do
I make it so?
