VB.Net is the bestest
I was happily coding away in VB.Net today (grrr) when I noticed a little weirdity in the intellisense popup.
The NotOverridable modifier defines a method of a base class that cannot be overridden in derived classes. All methods are NotOverridable unless marked with the Overridable modifier. You can use the NotOverridable modifier when you do not want to allow an overridden method to be overridden again in a derived class.
Makes C++ look simple.
