using Microsoft.Extensions.Logging;

namespace OdeToFood
{
    public class Startup
    {
        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.AddScoped<IRestaurantData, InMemoryRestaurantData>();
            services.AddMvcCore();
            services.AddSingleton(provider => configuration);
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {

            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            //app.UseRuntimeInfoPage();

            app.UseFileServer();

            app.UseMvc(ConfigureRoutes);

            app.Run(async (context) =>
            {
                await context.Response.WriteAsync("Hello World!");
            });
        }

        private void ConfigureRoutes(IRouteBuilder routeBuilder)
        {
            routeBuilder.MapRoute("Default", "{controller=Home}/{action=Index}/{id?}");
        }
    }
}

推荐答案

解决方案:使用AddMvc()代替Startup.cs中的AddMvcCore()，它将起作用.

Solution: Use AddMvc() instead of AddMvcCore() in Startup.cs and it will work.
