Why does it''s Clone() method return an object, instead of an ArrayList? All it does is force me to cast to an ArrayList whenever I use Clone().

ArrayList.Clone() is an implementation of the ICloneable interface. And ICloneable.Clone() is defined to return an Object type.

edit: and C# doesn't support covariant return types.

What is a covariant return type? Object can hold refs and boxing value types.
