在没有Microsoft.NET.Sdk.Web的情况下使用Razor

我正在编写简单的consoleApp(netcoreapp2.0)

<Project Sdk="Microsoft.NET.Sdk">

并希望用mvc运行webserver.

class Program
{
    static void Main(string[] args)
    {
        WebHost.CreateDefaultBuilder()
            .ConfigureServices(services => services.AddMvc())
            .Configure(app => app.UseDeveloperExceptionPage().UseMvcWithDefaultRoute())
            .UseHttpSys().Build().Run();
    }
}

public class HomeController : Controller
{
    [HttpGet] public ActionResult Index() => View("Index");
}

GET http // localhost：5000时收到错误

One or more compilation references are missing. Ensure that your project is referencing ‘Microsoft.NET.Sdk.Web’ and the ‘PreserveCompilationContext’ property is not set to false.

可能的原因是Razor Engine.
我怎样才能使它工作？我错过了什么？

您的Index.cshtml视图文件中缺少@using可能导致该错误消息.尝试绕过索引视图,只需从控制器返回一个字符串,以查看错误消息是否消失.

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            WebHost.CreateDefaultBuilder()
                .ConfigureServices(services => services.AddMvc())
                .Configure(app => app.UseDeveloperExceptionPage().UseMvcWithDefaultRoute())
                .UseHttpSys().Build().Run();
        }
    }

    public class HomeController : Controller
    {
        [HttpGet] public string Index() => "Hello World!";
    }
}

的csproj
