I am using this version 1.1.1 with NTLM authorization in my startup below so I can utilize dotnet run in a development environment. However, all my client requests to the server result in a 401 when I have the [Authorize] attribute on a controller. How do I tell webpack to forward my credentials? All the research I have done was directing me to add the properties to the devServer property in my webpack.config.

  public class Program
  {
    public static void Main(string[] args)
    {
      var host = new WebHostBuilder()
// support dotnet run with windows auth in debug mode
#if DEBUG
        .UseWebListener(opts =>
        {
          opts.ListenerSettings.Authentication.Schemes = Microsoft.Net.Http.Server.AuthenticationSchemes.NTLM;
        })
#else
          .UseKestrel()
#endif
          .UseContentRoot(Directory.GetCurrentDirectory())
          .UseIISIntegration()
          .UseStartup<Startup>()
          .Build();

      host.Run();
    }
  }
}
