How to outline the Round Corners effect?

Hi,

How do I outline the Round Corners effect?

I have drawn a rectangle outline, and applied the Round Corners effect. I need to now outline both the stroke (easy) *and* the round corners effect. What I need is a path, containing the outline including rounded corners.

I'm trying to export an illustration to XAML and it doesn't seem to support the round corners effect, thus it needs to be part of the path and not an effect.

Any help would be appreciated.

Thanks!
