Setting ThemeManager.DesignModeTheme="MetroWhite" on my ribbon window via xaml does not change the appearance of the window in the Visual Studio designer. At runtime the theme gets applied without any problems. For example "Classic" theme works in designer, but not the metro themes.
Could the problem be relatet to the fact, that ThemesMetroThemeCatalogRegistrar.Register() will only be called at runtime?
