How to find in code the parent Window or WinForm of a WPF control?

Question

I have a situation where I need to find the parent Window or WinForm which is hosting the WPF control. I need to get the handle of either the parent Window or WinForm whatever the case may be.

The problem is when the WPF control is hosted in a WinForm using ElementHost. How can I find the Handle of the hosting WinForm from a WPF control.

var parentHandle = presentationSource.Handle;
