无法让我的Asp.Net Core项目在localhost上发布到文件夹

当我从Visual Studio> IIS Express运行它时，我的Asp.Net Core 2.0 MVC应用程序正常工作，但在我发布到文件夹（c：\ inetpub \ TSGOnline）（TSGOnline是我的解决方案的名称）后，我只看到此错误消息浏览器：It tells me that changing environment to Production, it will work

但在Visual Studio中，我确实将ASPNETCORE_ENVIRONMENT设置为Production . As far as I can tell, the environment is Production

我的操作系统是Windows 10，IIS版本是10.0.15063.0 .

Program.cs中：

using System.IO;
    using Microsoft.AspNetCore;
    using Microsoft.AspNetCore.Hosting;
    namespace TSGOnline
    {
        public class Program
        {
            public static void Main(string[] args)
            {
                BuildWebHost(args).Run();
            }

            public static IWebHost BuildWebHost(string[] args) =>
                WebHost.CreateDefaultBuilder(args)
                    .UseKestrel()
                    .UseContentRoot(Directory.GetCurrentDirectory())
                    .UseIISIntegration()
                    .UseStartup()
                    .Build();
        }
    }

Startup.cs：

using Microsoft.AspNetCore.Builder;
    using Microsoft.AspNetCore.Hosting;
    using Microsoft.Extensions.Configuration;
    using Microsoft.Extensions.DependencyInjection;
    using TSGOnline.Models;
    using Microsoft.EntityFrameworkCore;

    namespace TSGOnline
    {
        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.AddDbContext(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
                services.AddMvc();
            }

            // 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();
                    app.UseBrowserLink();
                }
                else
                {
                    app.UseExceptionHandler("/Home/Error");
                }

                app.UseStaticFiles();

                app.UseMvc(routes =>
                {
                    routes.MapRoute(
                        name: "default",
                        template: "{controller=TSG}/{action=Index}/{id?}");
                });
            }
        }
    }

我的csproj：I wasn't able to paste it as code, so had to use image

我花了两天谷歌搜索，试图弄清楚这一个，但作为一个总的菜鸟，我可能不会总是知道答案是什么时候在我面前...请帮助？
