XAML-Parse-Ausnahme:Der Wert des Attributs {StaticResource PhoneAccentBrush} liegt außerhalb des gültigen Bereichs

Question

Ich habe ein Problem mit einer Ausnahme und konnte keine Antwort darauf finden, wie ich das Problem beheben kann.Der Wert des Attributs {StaticResource PhoneAccentBrush} liegt außerhalb des gültigen Bereichs.

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")));

Wenn ich in Windows Phone auf die Schaltfläche App_info_Button klicke, tritt die Ausnahme bei System.Windows.Apllication.LoadComponent auf. In App_info.g.i.cs stammt der obige Code aus dieser Datei.

Hier ist die Content-Panel-Definition in App_info.xaml

    <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">

        <TextBlock x:Name="PageTitle" Text="App Infos" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
    </StackPanel>

    <!--ContentPanel - place additional content here-->
    <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        <TextBlock Height="311" HorizontalAlignment="Center" Margin="25,32,0,0" Name="textBlock1" Text="This Application is designed ...." 
                   VerticalAlignment="Center" Width="425" Style="{StaticResource PhoneAccentBrush}" />
    </Grid>
</Grid>    
</phone:PhoneApplicationPage>

Dies ist der Stack-Trace

Das Problem liegt in dieser Zeile:

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

Sie versuchen, einen Pinselressourcenwert auf einen Stil festzulegen, was die Ausnahme verursacht.Sie könnten versuchen, das XAML wie folgt zu ändern:

<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}" />
