please don't drop the ball (like sun did) microsoft
i did a little experiment where i had a directx context under some wpf controls.
FAILURE
The WPF control (top-right box) just burns a hole right through the directx context. This pretty much makes WPF useless for any gamedevelopment. wtf. hopefully this will change, but i have not received a response to a timeline on the not very useful microsoft wpf forums.
