  public static void Main(string[] args) {
   var config = new ConfigurationBuilder().AddCommandLine(args).AddEnvironmentVariables("ASPNETCORE_").Build();

   var host =
    new WebHostBuilder().UseConfiguration(config).UseKestrel(ConfigHttps()).UseContentRoot(
     Directory.GetCurrentDirectory()).UseIISIntegration().UseStartup<Startup>().Build();
   
   host.Run();
  }

  private static Action<KestrelServerOptions> ConfigHttps() {
   return x => {
    var pfxFile = Path.Combine(Directory.GetCurrentDirectory(), "*.pfx");
    //password  Fill in the key of the application 
    var certificate = new X509Certificate2(pfxFile, "password");
    x.UseHttps(certificate);
   };
