@Naveen61097 May your problem the same as described here #4331

I don’t think so. In my case the shadow is not working in windows 11 too.

Thanks @AbdAlghaniAlbiek, I agree it should be basically the same issue.

@Naveen61097 see my comment here, this is also called out in our sample app. Adding a CornerRadius to a panel changes its clipping behavior when there's content, so you need to nest an element. This generally isn't a problem with any templated control when applying a card shadow, but if you're adding it to a general panel yourself then you need to do this extra bit of work.
