当我使用 Windows 服务运行我的网站时，我无法访问 wwwroot 中的 index.html

当我使用Windows 服务运行我的网站时，我无法访问 wwwroot 中的静态文件，但是当我使用IIS Express 或 IIS时它可以工作。我使用 Asp.Net Core 2.2 构建该项目。

控制器中的动作没问题，只是无法访问静态文件。

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        var df = new DefaultFilesOptions();
        df.DefaultFileNames.Add("Index.html");
        app.UseDefaultFiles(df);
        app.UseStaticFiles();
        app.UseMvc();
    }
}


public class Program
{
    public static void Main(string[] args)
    {
        var isService = !(Debugger.IsAttached || args.Contains("--console"));
        if (isService)
        {
            var pathToExe = Process.GetCurrentProcess().MainModule.FileName;
            var pathToContentRoot = Path.GetDirectoryName(pathToExe);
            Directory.SetCurrentDirectory(pathToContentRoot);
            var host = CreateWebHostBuilder(args.Where(arg => arg != "--console").ToArray()).Build();
            host.RunAsService();
        }
        else
        {
            WebHost.CreateDefaultBuilder(args).UseStartup<Startup>().Build().Run();
        }
    }
    static int Port = 9099;
    public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
        .UseKestrel(options => { options.Listen(IPAddress.Any, Port); })
        .UseStartup<Startup>();
}
