如何使选项卡控件在WPF中填充DockPanel的中心

<Window x:Class="WpfApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="450" Width="800">
    <DockPanel>
        <!-- 其他停靠的控件 -->
        <Button DockPanel.Dock="Top" Content="Top Button"/>
        <Button DockPanel.Dock="Left" Content="Left Button"/>

        <!-- 使TabControl填充DockPanel的中心 -->
        <TabControl DockPanel.Dock="Fill">
            <TabItem Header="Tab 1">
                <Grid>
                    <!-- Tab 1的内容 -->
                    <TextBlock Text="Content of Tab 1"/>
                </Grid>
            </TabItem>
            <TabItem Header="Tab 2">
                <Grid>
                    <!-- Tab 2的内容 -->
                    <TextBlock Text="Content of Tab 2"/>
                </Grid>
            </TabItem>
        </TabControl>
    </DockPanel>
</Window>
