WPF，自定义的控件，动态引用资源为什么不见效
一个自定义的控件CustomControl1：
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WPF3">
<Style x:Key="aa" TargetType="Border">
<Setter Property="Background" Value="Red"/>
</Style>
<Style TargetType="{x:Type local:CustomControl1}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:CustomControl1}">
<Border Style="{DynamicResource aa}" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
public class CustomControl1 : Control
{
static CustomControl1()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomControl1), new FrameworkPropertyMetadata(typeof(CustomControl1)));
}
}
