I am trying configure IHostBuilder and getting following error.

Building this implementation of IWebHostBuilder is not supported.

I am not sure why this is complaining about IHostBuilder. My IHostBuilder configuration in Program.cs:

 var host = Host.CreateDefaultBuilder(args).
                    UseWindowsService().
                    ConfigureWebHostDefaults(webBuiler =>
                    {
                        webBuiler.UseKestrel(k =>
                        {
                            k.Listen(IPAddress.Parse(componentsModel.LaunchSetting.LaunchIP), componentsModel.LaunchSetting.LaunchHTTPSPort, listenOptions =>
                            {
                                if (certificate != null)
                                {
                                    listenOptions.UseHttps(certificate);
                                }
                            });
                            k.Listen(IPAddress.Parse(componentsModel.LaunchSetting.LaunchIP), componentsModel.LaunchSetting.LaunchPort);
                        }).
                        UseContentRoot(Directory.GetCurrentDirectory()).ConfigureLogging(logging =>
                        {
                            logging.SetMinimumLevel(logLevel);
                            logging.AddDebug();
                            logging.AddFile(f =>
                            {
                                f.LogDirectory = logDirectory;
                                f.FileName = fileName;
                            });
                        }).UseStartup<Startup>()
                        .UseApplicationInsights()
                        .Build()
                        .Run();
                    });

CodePudding user response：

remove these two lines

  .Build()
  .Run();

it should part of main method

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