Argh, no one corrected him for mixing up covariance and contravariance?! 😐

[@rauIkat]

It would be nice for some people to explain why, let's do it:
- Covariance(out)
· Enables you to use a more derived type than originally specified.
· You can assign an instance of IEnumerable (IEnumerable(Of Derived) in Visual Basic) to a variable of type IEnumerable.
- Contravariance(in)
· Enables you to use a more generic (less derived) type than originally specified.
· You can assign an instance of IEnumerable (IEnumerable(Of Base) in Visual Basic) to a variable of type IEnumerable.
- Invariance
· Means that you can use only the type originally specified; so an invariant generic type parameter is neither covariant nor contravariant.
· You cannot assign an instance of IEnumerable (IEnumerable(Of Base) in Visual Basic) to a variable of type IEnumerable or vice versa.
