Differing covariant arrays [Answered]

Why does this work

var xs = new string[] {};
object[] ys = xs;

var xs = new string[] {};
object[] ys = xs;

but this doesn't?

var xs = new int[] {};
object[] ys = xs;

var xs = new int[] {};
object[] ys = xs;

also idk what to name this post

Variance only works for reference conversions int->object is a boxing conversion

That makes sense I think this is also the same for variance in interfaces, right?
