ASP.net MVC Razor view on Mono Mac

Question

I created an ASP.net MVC application using Visual Studio Community Edition for Mac. When I ran the default HomeController and Index view work fine. Then I made a BookController and inside views added a folder Book and Index.cshtml file. However I keep getting the following error:

System.InvalidOperationException The view found at '~/Views/book/Index.cshtml' was not created.

Description:

HTTP 500.Error processing request.

Details:

I Googled around and people said I have to make sure the web.config inside views folder is as follows:

<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

That is it matches the version of system.web.mvc and looking inside system.web.mvc the version is:

5.2.3

And the default view in HomeController works. I am trying out ASP.net MVC on Mac first time and never had this type of problem on Windows.

Any help is welcome.

Update Controller code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using TestMvcFromMac.Models;

namespace TestMvcFromMac.Controllers
{
 public class BookController : Controller
 {

    //Category category = new Category();


    public ActionResult Index()
    {
        return View ();
    }


 }
}

medium Visual Studio for Mac 2017 MVC version 5.3.2

I had the exact same problem. My Index views was working and other actions was not, giving the same error. I don't know why but when I add a route attribute manually in the beginning of the action in the controller, it was the solutions for my case

steps 1) add following line to the routeconfig.cs file

 routes.MapMvcAttributeRoutes();

2) add route attribute to the action manually like

  [Route("ViewName/ActionName/")]
    public ActionResult ActionName()
    {....
  return View(the_model);
   }
