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.

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 (); } } } 2 Answers

I am guessing that the problem might happen because you are creating all the stuff manually and not letting template engine generate something for you like in visual studio in windows (Personally did not try Mac version so I dont know exactly how it looks like). Anyway lets suppose you have created your controller and then Book folder. But there is something to configure manually as well if its not configured, and that is routing for current controller.
You have to set routing logic in RouteConfig file class, so you would have something like this:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Book" , action = "Index", id = UrlParameter.Optional } ); Refere to this question for more details here.
Another version I guess is setting the view name inside return statement itself like this:
return View("Index") If this is not the case please let me know so I can see any other alternative for this problem...

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); }
