public partial class App : System.Windows.Application
{
    public App()
    {
        Serve.Run(silence: true);   // 静默启动
    }
}

using Microsoft.Extensions.Hosting;
using System;
using System.Windows;

namespace WpfApp1;

public partial class App : Application
{
    private readonly IHost _host;

    public App()
    {
        _host = Serve.Run(silence: true);
    }

    protected override void OnExit(ExitEventArgs e)
    {
        _host.StopAsync();
        _host.Dispose();

        base.OnExit(e);
    }
}
