.net WPF App has visually different style than WinFORMS on Windows 8

Hey Everyone,
Developing a WPF application using VS2012, on Windows 8.  This is a standard desktop app.  I'm using WPF because it has the Ribbon as a standard control, where as WinForms does not. 

However, I'm noticing that when I run my app, it doesn't take on the local Windows 8 Desktop theme settings when starting, it looks like an ugly non aero themed app...is there a setting somewhere that I'm missing in the form creation that I need to set to make it look like every other Windows 8 Desktop window?

Thanks
john
