A few weeks ago, I linked to a list of What Great .NET Developers Should Know.  I then came up with the idea of adding more of my own through my own experiences.  I found this list to be helpful and not just random trivia and picking points out of the .NET class libraries.  If anyone has more to add or to nitpick my list, please let me know...
