I have an orchestration that I've tested with file transports and works
fine. The orchestration itself really does nothing. It receives and
file on an inbound port and sends it to an outbound port using a FILE
transport type.

I then used the BizTalk Web Service Publishing Wizard to create a web
service. I created a web page front end and filled the object criteria
necessary to pass to the web service proxy. This fails at runtime with
an "Object reference" exception on the Me.Invoke() sub that was created
by the web service subscription wizard when I added the web reference
to the web project.

I've looked to see that the object that needs to be passed to the proxy
is getting created properly. I've also got the ASPNET process user in
the "BizTalk Isolated Host Users" group. This exception appears to come
from the internal SoapHTTPClientProtocol class.

Has anyone ever ran across this issue and fixed it (without a hammer)?

Thanks!
