Can I use that effect on my controls just like the BlurEffect? If it's not available, is there a way to "acquire" it? Perhaps via the Reflector?
Which "Aero" effect are you referring to?
You can extend the glass effects into your client area in a WPF application via DwmExtendFrameIntoClientArea.
If you're just after the blurring, you could use BlurBitmapEffect from WPF directly.
