無法在asp.net核心的startup.cs文件中找到Use.RunTimePageInfo()方法

Question

我正在 Ubuntu 16.04 .Net Core 1.0.0 框架中學習 Scott Allen 的 Asp.Net core Pluralsight 課程。 我無法在 StartUp.cs 文件的 Configure 方法中找到 app.UseRuntimeInfoPage 方法，即使我已經包含了 Microsoft.AspNetCore.Diagnostics。 該框架在提供的功能方面是否對非 Windows 操作系統有限制？

來自 Scott Allen 課程的 StartUp.cs 代碼

using Microsoft.AspNet.Builder;
using Microsoft.AspNet.Hosting;
using Microsoft.AspNet.Http;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Configuration;
using OdeToFood.Services;

namespace OdeToFood
{
    public class Startup
    {
        public Startup()
        {
            var builder = new ConfigurationBuilder()
                            .AddJsonFile("appsettings.json");
            Configuration = builder.Build();
        }

        public IConfiguration Configuration { get; set; }

        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit http://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();
            services.AddSingleton(provider => Configuration);
            services.AddSingleton<IGreeter, Greeter>();
        }

        // This method gets called by the runtime. 
        // Use this method to configure the HTTP request pipeline.
        public void Configure(
            IApplicationBuilder app,
            IHostingEnvironment environment,
            IGreeter greeter)
        {
            app.UseIISPlatformHandler();

            if (environment.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            
            app.UseRuntimeInfoPage("/info");

            app.UseFileServer();

            app.UseMvcWithDefaultRoute();

            app.Run(async (context) =>
            {
                var greeting = greeter.GetGreeting();
                await context.Response.WriteAsync(greeting);
            });

        }

        // Entry point for the application.
        public static void Main(string[] args) => WebApplication.Run<Startup>(args);
    }
}

此功能前段時間已被刪除。 https://github.com/aspnet/Home/issues/1632

此外，它似乎計划在不確定的時間回來。 https://github.com/aspnet/Diagnostics/issues/280

所以現在你可以從你的 startup.cs 中刪除它； 或添加代碼並從此提交創建您自己的版本： https : //github.com/aspnet/Diagnostics/commit/af19899927516718bdc05507612dcc17901fb937

我不提供代碼示例，因為代碼在上面提到的提交中。

更新：

似乎問題 #280 已更新以聲明該功能根本不會恢復。

Use.RunTimePageInfo（）沒有這樣的方法......

請顯示啟動代碼
