I still maintain an internal WinForms app in c#. Even with the very old (.net 1.0) code everywhere, lot's of spaghetti, inline sql (including the sql injection variety) etc, it's still our most maintainable application and I love getting the chance to work on it. Most other apps we have, even the ones far simpler than this one, contain just as much spaghetti but distributed over 15 layers to the point where their incomprehensible. In hindsight I'm not convinced replacing drag'n'drop coding with "architecture" was a good move.
