Haha. I hate to say this, but in my career, I keep coming across projects that are mostly C# with a small percentage of awful VB.Net code. (I do find GOOD VB.Net code on the 'net.) For example, in my first job out of college, 95% of the code was in C#. There was one group of dlls written in VB.Net where the developer had all methods take a single array of objects as THE argument. Even weirder was that almost all of the values being passed on the stack belonged as object-level fields. The code was an example of how NOT to use weak typing. It was very clear to me that the original developer spent a few months on the code... I re-wrote it all (from scratch) in 3 days!

I once worked with a programmer who wrote code like that. He yelled at me (in front of the big boss) for getting rid of it. It turns out he wasn't aware that .Net puts a stack trace in Exception objects! The real lesson that *I* learned is "old habits die hard"; he was still using techniques from back in the C++ / COM days.
