Thanks Mohamed2004 for reaching to Adobe.
XD currently supports exporting to PNG, JPG, SVG, PDF and After Effects.
XAML is not supported for the time being.
As Nawneet mentioned that XAML is not supported as of now. I found the UserVoice link for the same request here: https://adobexd.uservoice.com/forums/353007-adobe-xd-feature-requests/suggestions/19394053-use-xaml-...
I would suggest submitting your feedback and upvote the request to add your voice.
Hope it helps.
