How do we show window of window form in grid or viewbox of wpf : in xml file:
    
    <viewbox name="viewbox1"></viewbox>
in C# code:
    
    windowformClass window1 = new windowformClass(); // this is the oject of window form. not wpf
    viewbox1.child = window1;
when i assign window1 to viewbox1 then it shows an error that cannot convert window form to system.window.elementUI
