Is it possible to set x:Name on an object that is created from C#, so it can be targeted from Visual State Manager?

[VincentH-Net]

This is possible in WPF with the WPF FrameworkElement.RegisterName method.
However I could not find an equivalent C# API in Windows App SDK. I also could not find an equivalent of the WPF Namescope class.

Is it possible?

E.g. in below XAML (from this SDK doc), if the ButtonBrush is created from C#, how can I target that brush from Visual State Manager XAML?

This is a blocker for supporting Visual State Manager in C# Markup 2 for Windows App SDK
Note that if setting x:Name from C# is possible, it will also be possible to create the VisualStateManager.VisualStateGroups from C#.

<ControlTemplate TargetType="Button">
  <Grid >
    <VisualStateManager.VisualStateGroups>
      <VisualStateGroup x:Name="CommonStates">

        <VisualStateGroup.Transitions>

          <!--Take one half second to transition to the PointerOver state.-->
          <VisualTransition To="PointerOver" 
                              GeneratedDuration="0:0:0.5"/>
        </VisualStateGroup.Transitions>
        
        <VisualState x:Name="Normal" />

        <!--Change the SolidColorBrush, ButtonBrush, to red when the
            Pointer is over the button.-->
        <VisualState x:Name="PointerOver">
          <Storyboard>
            <ColorAnimation Storyboard.TargetName="ButtonBrush" 
                            Storyboard.TargetProperty="Color" To="Red" />
          </Storyboard>
        </VisualState>
      </VisualStateGroup>
    </VisualStateManager.VisualStateGroups>
    <Grid.Background>
      <SolidColorBrush x:Name="ButtonBrush" Color="Green"/>
    </Grid.Background>
  </Grid>
</ControlTemplate>
