Transparency not working on Windows 7 (0.9.0)

[bg117]

I am using FluentWPF in my application. It works perfectly on Windows 10, but the Acrylic thing doesn't seem to work on Windows 7 (at least in my virtual machine).

Screenshots:

^ Windows 7. The grid has the Acrylic effect. The background is blue.

^ Windows 10 (host PC). Here Acrylic works fine.

Another screenshot from my Windows 7 VM:

Another thing, if AllowsTransparency is set to true, the window becomes transparent with no blur. With the window tint of course.

Windows 7 has huge difference in Aero Glass Api, i think you can try to do this effect by yourself:

And don't forget to check OS: if (Environment.OSVersion.Version.Major >= 6){}
I love this system, but Windows 7 is depreciated and extended support ended more then year ago, so I don't think it makes a lot of sense to support all style features on this OS..
