无法在aspnet核心的startup.cs文件中找到Use.RunTimePageInfo()方法

Question

我跟随Scott Allen在Ubuntu 16.04 .Net Core 1.0.0框架中的Asp.Net核心复数课程.我无法在StartUp.cs文件中的Configure方法中找到app.UseRuntimeInfoPage方法,即使我已包含Microsoft.AspNetCore.Diagnostics.在提供的功能方面,框架是否对非Windows操作系统有限制？

来自Scott Allens课程的StartUp.cs代码

    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();
            }

            // 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(args);
        }
    }

这个功能不久前被删除了. https://github.com/aspnet/Home/issues/1632

此外,似乎计划在不确定的时刻回来. https://github.com/aspnet/Diagnostics/issues/280

所以现在你可以从startup.cs中删除它; 或者从这个提交中添加代码并创建自己的版本:https: //github.com/aspnet/Diagnostics/commit/af19899927516718bdc05507612dcc17901fb937

我不提供代码示例,因为代码在上面提到的提交中.
