SizeAnimation能否实现控制Window的大小的动画？

Question

SizeAnimation可以实现控件的大小变化动画，可以指定StoryBoard.TargetName和StoryBoard.TargetProperty。
但是，我不知道如何控制窗体？窗体好像没有Name属性吧？

下面的代码，出现崩溃。该如何修改？
<Button Width="100" Height="100">
                    <Button.Triggers>
                        <EventTrigger RoutedEvent="Button.Click">
                            <BeginStoryboard>
                                <Storyboard>
                                    <DoubleAnimation Storyboard.TargetName="MainWindow" Storyboard.TargetProperty="(Window.Height)" From="0" To="500" Duration="00:00:01.8"></DoubleAnimation>
                                </Storyboard>
                            </BeginStoryboard>
                        </EventTrigger>
                    </Button.Triggers>
</Button>
