WPF Aero window without shadow

I am aware of the following question: I want to disable the shadow effect on a specific aero window

However, I still need the DWM blur/reflections behind my Aero wind开发者_StackOverflow中文版ow, so I can't create a custom transparent one. How would I approach that? I could handle the reflections by myself, but I don't know how to create a blur.

Done it using DwmEnableBlurBehindWindow. :)
