If I remove the ref, it works as expected, that is to say I can give a derived class as parameter.
Why are you using the ref to begin with?
What the logic here?
Consider this:
class C : A {}
void incr(ref A a) {
a = new C;
}
B b = new B;
incr(b);
// oops b now got rebound to a C instead of to a B, which breaks
everything
