[edit]I think this is wrong: the overriding return type must be a sub-type of the original type, not any related type, or usually subtype. Always a subtype. That's why it is called covariant. Or am I mistaken? Jirka6 (talk) 13:31, 28 November 2007 (UTC)
The facts have changed since the introduction of generics in C#.
[edit]This article shall be updated for consistency with this other article: Covariance and contravariance_(computer science)#Generic types
