Windows 10 with management template and AdaptiveTrigger

Question

How can I use AdaptiveTrigger in Templated Control in Windows 10 (I use Windows 10 Pro Insider Preview Build 10074). The Window.Current.SizeChanged event does not fire when the window is resized. What is the correct way to control fluid? Here is what I am trying to do, but nothing happens when the screen is resized:

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>

I don't think AdaptiveTriggers works in that style. The only thing I have is to work directly in UserControl or Grid inside the page. I know for sure that they do not work in a DataTemplate. VisualStateManager should be up to the contents of the controls too, I believe. Try a different approach:

        <!--in app.xaml or something-->
    <ControlTemplate x:Key="controlTemplate1" TargetType="MyControl">
        <Border Background="Green"/>
    </ControlTemplate>
    <ControlTemplate x:Key="controlTemplate2"  TargetType="MyControl">
        <Border Background="Blue"/>
    </ControlTemplate>

    <!--in your page-->
    <Grid>
        <VisualStateManager.VisualStateGroups>
            <VisualStateGroup x:Name="visualStateGroup" >
                <VisualState>
                    <VisualState.StateTriggers>
                        <AdaptiveTrigger MinWindowWidth="720" />
                    </VisualState.StateTriggers>
                    <VisualState.Setters>
                        <Setter Target="control.Template" Value="{StaticResource controlTemplate1}"/>
                    </VisualState.Setters>
                </VisualState>

                <VisualState>
                    <VisualState.StateTriggers>
                        <AdaptiveTrigger MinWindowWidth="0" />
                    </VisualState.StateTriggers>
                    <VisualState.Setters>
                        <Setter Target="control.Template" Value="{StaticResource controlTemplate2}"/>
                    </VisualState.Setters>
                </VisualState>
            </VisualStateGroup>
        </VisualStateManager.VisualStateGroups>

        <MyControl x:Name="control" Template="{StaticResource controlTemplate1}"/>
    </Grid>
