My app is generally designed for dark theme, and I\'m using StaticResources So if the user changes his phone\'s theme to light the app
I just wanted to recommend Jeff Wilcox's 'Windows Phone Theme Manager' nuget package as an easy way to implement this functionality for both light and dark themes.
http://www.nuget.org/packages/PhoneThemeManager/
Just add a function call to the App constructor:
ThemeManager.ToDarkTheme();
or
ThemeManager.ToLightTheme();
