Is it possible to use DirectX 10 (I am using SlimDX) with WPF\'s D3DImage? The only examples and docs I can find only show using DX9 surfaces.
Not out of the box as far as I know. WPF is based on DirectX, but as WPF is also supported on Windows XP it's based on DirectX 9.
I do know that it's possible to use DirectX 10 with WPF, but then your application won't be able to run on XP.
There's a library for WPF called Bling which supports DirectX 10 (on Vista and Windows 7) which might be of interest to you. You can find it here. I don't know how mature it is though.
Also, I ran into this blog (mostly in french) who speaks about using DirectX 10 with WPF.
Lastly there's a good introduction to using D3DImage with DirectX over at CodeProject
I know this doesn't exactly answer your question, but I thought I'd share it with you anyways. Best of luck.
