I am making a webservice call into to a PeopleSoft service and everything
works except raising exceptions.  

As an example if I fail authentication I get the following response:

<?xml version="1.0"?>
<soap:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
 <soap:Header>
   <soap:Fault>
     <faultcode>FailedAuthentication</faultcode>
     <faultstring>Username or Password not valid for Component
Interface.</faultstring>
   </soap:Fault>
 </soap:Header>
 <soap:Body/>
</soap:Envelope>

But this response is not raising an exception in my code.
It was my understanding that faults raise an exception in the client but I
am unable to get that to happen in the proxy C# (SoapHttpClientProtocol).

thanks.
