Randomly: worked with the CheckedListBox tonight. It's interesting to run into "getter/setter" type methods in the .NET universe. One would assume a collection that specifically supported setting constituent objects as "selected" or "checked" but instead there are methods like: GetItemCheckedState and SetItemCheckedState.
It would be interesting to have the Windows Forms equivalent to the annotated base class library reference. Perhaps tomorrow I'll try to peak at the source code.
