使用ReactiveUI创建类似Visual Studio的启动窗口的最佳方法是什么？

Install-Package ReactiveUI

<Window x:Class="YourNamespace.StartupWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Startup Window" Height="450" Width="800">
    <Grid>
        <StackPanel>
            <TextBlock Text="Welcome to My IDE" FontSize="24" HorizontalAlignment="Center" Margin="20"/>
            <Button Content="Start" HorizontalAlignment="Center" Margin="20" Click="StartButton_Click"/>
        </StackPanel>
    </Grid>
</Window>

using ReactiveUI;
using System.Reactive.Linq;
using System.Windows;

namespace YourNamespace
{
    public partial class StartupWindow : ReactiveWindow
    {
        public StartupWindow()
        {
            InitializeComponent();
            this.WhenAnyValue(x => x.StartButton).Subscribe(button => button.IsEnabled = true);
        }

        private void StartButton_Click(object sender, RoutedEventArgs e)
        {
            this.ShowMainWindow();
        }

        private void ShowMainWindow()
        {
            var mainWindow = new MainWindow();
            mainWindow.Show();
            this.Close();
        }
    }
}

<Window x:Class="YourNamespace.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Main Window" Height="450" Width="800">
    <Grid>
        <TextBlock Text="Welcome to the Main Window" FontSize="24" HorizontalAlignment="Center" Margin="20"/>
    </Grid>
</Window>

using System.Windows;

namespace YourNamespace
{
    public partial class App : Application
    {
        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);
            var startupWindow = new StartupWindow();
            startupWindow.Show();
        }
    }
}
