XAML parse Exception: Attribute {StaticResource Ph

I have a problem with an Exception, couldn't find the answer on how to fix it. Attribute {StaticResource PhoneAccentBrush} value is out of range.

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")));

In windows phone when i click on the button App_info_Button the exception happens on System.Windows.Apllication.LoadComponent In App_info.g.i.cs , the code above is from that file.

here is the content Panel definition on App_info.xaml

This is the Stack trace

The problem is in this line:

<TextBlock Height="311" HorizontalAlignment="Center" 
           Margin="25,32,0,0" Name="textBlock1" 
           Text="This Application is designed ...." 
           VerticalAlignment="Center" Width="425" 
           Style="{StaticResource PhoneAccentBrush}" />

You are trying to set a brush resource value to a style, which is what is causing the exception. You could try changing the XAML to:

<TextBlock Height="311" HorizontalAlignment="Center" 
           Margin="25,32,0,0" Name="textBlock1" 
           Text="This Application is designed ...." 
           VerticalAlignment="Center" Width="425" 
           Style="{StaticResource PhoneTextNormalStyle}"
           Foreground="{StaticResource PhoneAccentBrush}" />
