如何在 Windows 10 的模板化控件中使用 AdaptiveTrigger（我使用 Windows 10 Pro Insider Preview Build 10074）。Window.Current.SizeChanged 事件不会在窗口大小更改时触发。进行流体控制的正确方法是什么？这是我尝试做的事情，但是更改屏幕大小时没有任何反应：

XAML template:
<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:App1">

    <Style TargetType="local:CustomControl1" >
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="local:CustomControl1">
                    <Border>
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="VisualSizeStates">

                                <VisualState x:Name="Small">
                                    <VisualState.StateTriggers>
                                        <AdaptiveTrigger MinWindowHeight="0" MinWindowWidth="0" />
                                    </VisualState.StateTriggers>
                                    <VisualState.Setters>

                                        <Setter Target="Rect.Fill" Value="Green"/>

                                    </VisualState.Setters>
                                </VisualState>

                                <VisualState x:Name="Big">
                                    <VisualState.StateTriggers>
                                        <AdaptiveTrigger MinWindowHeight="1000" MinWindowWidth="1000" />

                                    </VisualState.StateTriggers>
                                    <VisualState.Setters>
                                        <Setter Target="Rect.Fill" Value="Blue"/>
                                    </VisualState.Setters>
                                </VisualState>
                            </VisualStateGroup>
                        </VisualStateManager.VisualStateGroups>
                        <Rectangle x:Name="Rect" Fill="Red" />
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>
