Folks,
My boss has given me an assignment.  Another company hosts web
services, and he wants me to write an internet application that uses
them.
So my question is: What do I need to know to do this?
I've already read a book on xml, another book on xml schemas, another
book on C#, and I've ordered a book on SOAP.  What else do I need to
know to program web services?  
Thanks,
Marvin Cohen
