Question

Why cant C<

Answer 1

What you are asking for is Covariance and Contravariance in Generics which is only applicaple for interfaces and delegates. You can check this

You can do the following in Framework >= 4:

interface IC where T : A

class C : IC  where T : A

IC ica = new C();

For your case you should extract an interface for class C
