如何将LinearGradientBrush设置为ContentPages的背景

Question

如何将LinearGradientBrush添加为App.xaml的ResourceDictionary中的ContentPage.Background？我的代码粘贴在下面：

<LinearGradientBrush EndPoint="0,1">
<GradientStop Color="LightBlue"
Offset="0.1" />
<GradientStop Color="DarkBlue"
Offset="1.0" />
</LinearGradientBrush>

由于LinearGradientBrush是一个预览概念，请不要忘记在App.xaml.cs中添加以下代码。

Device.SetFlags(new string[] {"Brush_Experimental" });

并将以下内容添加到App.xaml:

<Application.Resources>
<ResourceDictionary>
<Style  TargetType="ContentPage" ApplyToDerivedTypes="True">
<Setter Property="Background">
<LinearGradientBrush EndPoint="0,1">
<GradientStop Color="LightBlue"
Offset="0.1" />
<GradientStop Color="DarkBlue"
Offset="1.0" />
</LinearGradientBrush>
</Setter>
</Style>
</ResourceDictionary>
</Application.Resources>
