[kucint]

Current behavior

On Desktop framework: ColorAnimation is not working On WinAppSdk framework: works fine

<Grid BorderThickness="3">
    <Grid.BorderBrush>
        <SolidColorBrush x:Name="SelectionFrameBorderBrush" Color="Transparent" />
    </Grid.BorderBrush>

    <VisualStateManager.VisualStateGroups>
        <VisualStateGroup x:Name="SelectionStates">
            <VisualState x:Name="Selected">
                <Storyboard>
                    <ColorAnimation Storyboard.TargetName="SelectionFrameBorderBrush" Storyboard.TargetProperty="Color" To="Red" Duration="0:0:0.2" />
                </Storyboard>
            </VisualState>
            <VisualState x:Name="Normal">
                <Storyboard>
                    <ColorAnimation Storyboard.TargetName="SelectionFrameBorderBrush" Storyboard.TargetProperty="Color" To="Transparent" Duration="0:0:0.2" />
                </Storyboard>
            </VisualState>
        </VisualStateGroup>
    </VisualStateManager.VisualStateGroups>

    <CheckBox Content="CheckBox"
              HorizontalAlignment="Center"
              VerticalAlignment="Center"
              IsChecked="False"
              Checked="CheckBox_Checked"
              Unchecked="CheckBox_Unchecked">
  </CheckBox>
</Grid>

  private void CheckBox_Checked(object sender, RoutedEventArgs e)
      => VisualStateManager.GoToState(this, "Selected", true);

  private void CheckBox_Unchecked(object sender, RoutedEventArgs e)
      => VisualStateManager.GoToState(this, "Normal", true);
