Why would you cast the thing to whatsthetype if you know you're going to
treat it as an IBar ??
If it implements IBar, cast it to IBar and live a happy life. If you use
IBar bar = foo as IBar;
IQuux quux = foo as IQuux;
you can find out what it implements by checking nullness. If you want to use
a type (in this case interface IBar) in .Net, you either statically type
your expression to be that type, or you go the reflection path. Even with
reflection, if you don't know the type beforehand, how on earth are you
going to make a program that's so intelligent that it figures out how to use
the type on the fly ...
