How to use DrawThemeTextEx in WPF

Question

Hi, I'm working on an application that displays text on Aero Glass. To make it readable I used a OuterGlowBitmapEffect, but, as also described here this is no longer possible in .NET 4 and the DropShadowEffect won't work for Glass either.

While searching for a solution I came across the native DrawThemeTextEx in DWMApi, but all examples I found were for WinForms and not for WPF.

So how can you use this in WPF?

Thanks
