I did some work last year with a team building web applications in VB.NET
and put together a (if I say so myself) faily decent couple of tutorials
on core UML diagrams and on mapping VB.NET to UML class diagrams. You can
view these for free at (everything on the site
is free, by the way - and feel free to post any useful resources you'd like
to share with other developers interested in OO programming).

Coming soon!
