在IIS上托管.net5.0核心Web API时出现问题（10.0.17763.1）

我在将.net core 5.0 Web API托管在IIS时遇到问题，因此我决定创建一个基本的即装即用版本（WeatherForecast）。同样，这在IIS上也不起作用（因此，我认为这不是我的代码）。我已经安装了.Net Core Hosting Bundle 5.0（V5.0.2），并重新启动了IIS（net stop was /y，net start w3svc）。

我的网站托管在https://authdev.XXXXXXXX.net/api/weatherforecast（其中XXXXXXXX.net在我的内部网络上）。该服务器是Microsoft Hyper-V Server2019。我有一个单独的应用程序池，在集成管道模式下，.Net CLR版本设置为“无托管代码”。我的网站设置了适当的绑定，并且配置正确。我已经通过创建一个.Net Core 5.0 MVC网站（开箱即用）从该服务器远程工作来确认这一点。我在进程外模式下得到404（并且相同的URL在本地与明显的服务器URL更改一起工作）。我在某一阶段添加了日志记录信息，并发现public void Configure(IApplicationBuilder app, IWebHostEnvironment env)Startup.cs中的方法未命中。

错误消息500.30-ASP.NET Core应用无法启动

我认为此消息表明我的托管环境已正确配置，但我的Web API（开箱即用）存在错误。

Program.cs

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder
                    .UseContentRoot(Directory.GetCurrentDirectory())
                    .UseKestrel()
                    .UseIISIntegration()
                    .UseStartup<Startup>();
            });
}

启动文件

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.AddControllers();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseHttpsRedirection();

            app.UseRouting();

            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });
        }
    }

我尝试在进程内和进程外模式下运行此命令
