how to use mui by vsto in ms office addin?

Mar 13, 2015 at 9:11 PM

i tried to use the mui in an office addin and vsto.
As I know are the restrictions from vsto that I can't use wpf windows directly. The only way to use wpf is to use a wpf control in a wpf host element on a winforms window.
I tried to use the modernWindow or a wpf window in the host element and it is not working.
I am now at the point that I have no idea what is to change to use mui as a wpf control ?!

Have anyone another experience to solve this scenario?

Thanks for advice!
