Unfortunately, you can't smooth it using the WindowChrome CornerRadius property.

You can achieve the same effect, but it requires a lot more work.

You have provide a custom style/control template, and add the corner radius on a root Border. Then you need to make sure to clip the border's contents to your corner radius.

I have an attached behavior that I use to do the clipping.

You get a really nice result, but it's much more work.
