[Mono-list] Web Services help

[Joel Gwynn]

Hey all.  I'm trying to use Amazon Web Services in an ASP.NET project.
 Two questions:

1. Is the wsdl2 tool the only way to use web services, or is there a
way to get mono to see web services that have been automatically added
to my App_WebReferences folder by Visual Studio?
2. Using the wsdl2 tool on debian linux, I get many errors:

Web Services Description Language Utility
Mono Framework v2.0.50727.42
Error: Object reference not set to an instance of an object
