在Ubuntu 16.04上运行简单的.Net Core MVC应用程序时出现内部服务器错误 [英] Internal Server Error while running a simple .Net Core MVC application on Ubuntu 16.04

问题描述

在Ubuntu上使用.Net core 1.0运行简单的"hello world"应用程序时，出现内部服务器错误.我确定我缺少一些简单的东西，但无法弄清楚它是什么.直到我在HomeController中将return Content("Hello, world!");替换为return View();，并将using System.IO;和.UseContentRoot(Directory.GetCurrentDirectory())添加到Program.cs为止.

I am getting an internal server error while running a simple "hello world" application using .Net core 1.0 on Ubuntu. I'm sure that I'm missing something simple, but can't figure out what it is. It was working until I replaced return Content("Hello, world!"); with return View(); in HomeController, and added using System.IO; and .UseContentRoot(Directory.GetCurrentDirectory()) to Program.cs.

我尝试将System和System.X添加到我在Startup.cs中的依赖项列表中无济于事.

I have tried adding System and System.X to my list of dependencies in Startup.cs to no avail.

using Microsoft.AspNetCore.Hosting;
using System.IO;

namespace aspnetcoreapp
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var host = new WebHostBuilder()
                .UseKestrel()
                .UseContentRoot(Directory.GetCurrentDirectory())
                .UseStartup<Startup>()
                .Build();

            host.Run();
        }
    }
}

            app.UseStaticFiles();

            app.UseMvc();
        }
    }

推荐答案

在project.json的buildOptions节点下，添加一个名为"preserveCompilationContext": true的条目，这将解决上述错误.

Under the buildOptions node in project.json, add an entry called "preserveCompilationContext": true and this should fix the above error.
