The presenter I saw also mentioned contra-variance.  I admit I was a little
lost when he talked about that, because I hadn't used variance before.  I
actually haven't used C# a whole lot.  I have used C# before, in college and
for one of my personal proejcts, but I haven't used it enough to make use of
its more interesting features which differ from older languages.

The presenter I saw also mentioned a way to name parameters in C# 4.0 so you
can pass parameters to functions in any order..  I thought that was something
that could definitely be useful.
