Tengo un problema con una excepción, no pude encontrar la respuesta sobre cómo solucionarlo. El valor del atributo {StaticResource PhoneAccentBrush} está fuera de rango.

System.Windows.Application.LoadComponent(this, new System.Uri("/PAK_phone_side;component/Views/About/App_info.xaml", System.UriKind.Relative));
        this.LayoutRoot = ((System.Windows.Controls.Grid)(this.FindName("LayoutRoot")));
        this.TitlePanel = ((System.Windows.Controls.StackPanel)(this.FindName("TitlePanel")));
        this.ApplicationTitle = ((System.Windows.Controls.TextBlock)(this.FindName("ApplicationTitle")));
        this.PageTitle = ((System.Windows.Controls.TextBlock)(this.FindName("PageTitle")));
        this.ContentPanel = ((System.Windows.Controls.Grid)(this.FindName("ContentPanel")));
        this.textBlock1 = ((System.Windows.Controls.TextBlock)(this.FindName("textBlock1")));

En Windows Phone cuando hago clic en el botón App_info_Button, la excepción ocurre en System.Windows.Apllication.LoadComponent En App_info.g.i.cs, el código anterior es de ese archivo.

aquí está la definición del Panel de contenido en App_info.xaml
