There are some very interesting posts I missed the last days. Since .NET 3.5 SP1 perfectly integrates WPF with DirectX, a number of cool effects can finally be applied:

Some of those effects were on Dax Pandhi’s wish list for WPF (http://blog.nukeation.com/post/My-wishlist-for-the-next-release-of-WPF.aspx) for quite some time.
More importantly, the integration of WPF and Direct3D might eliminate the need for a custom overlay control for the MenuKiller Control, which is a major performance hog (I currently use an overlay similar to this: http://blogs.msdn.com/pantal/archive/2007/07/31/managed-directx-interop-with-wpf-part-2.aspx).
I was so glad to run into your article. I have a DVD application created in Direct X. Are you saying this should now be portable into WPF so that I can make some decent looking buttons, progress bars, etc. for it?
