MVC controller using EntityFramework 404 Error - asp.net-mvc

Question

Trying to add a MVC controller with read/write action using EntityFramework. My controller name is UsersController. When i hit add, VS creates a folder named Users and subdirectories like Create, Edit, Index etc.
My Entity-Model table name is Users.
When i try to reach them with links below, i got "The resource cannot be found 404" error.
http://localhost:64871/Users <br>
http://localhost:64871/Users/Index<br>
http://localhost:64871/Users/Create
I can reach links which i created with empty MVC controller option.
http://localhost:64871/Home<br>
http://localhost:64871/Home/Test
What can be wrong? Should i add some values to my RouteConfig file?
My RouteConfig.cs
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
My userscontroller look like;
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace Aplatform.Controllers
{
public class UsersController : Controller
{
private dbEntities db = new dbEntities();
//
// GET: /Users/
public ActionResult Index()
{
return View(db.Users.ToList());
}
//
// GET: /Users/Details/5
public ActionResult Details(Guid id = null)
{
Users users = db.Users.Find(id);
if (users == null)
{
return HttpNotFound();
}
return View(users);
}
//
// GET: /Users/Create
public ActionResult Create()
{
return View();
}
//
// POST: /Users/Create
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(Users users)
{
if (ModelState.IsValid)
{
users.ID = Guid.NewGuid();
db.Users.Add(users);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(users);
}
//
// GET: /Users/Edit/5
public ActionResult Edit(Guid id = null)
{
Users users = db.Users.Find(id);
if (users == null)
{
return HttpNotFound();
}
return View(users);
}
//
// POST: /Users/Edit/5
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit(Users users)
{
if (ModelState.IsValid)
{
db.Entry(users).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
return View(users);
}
//
// GET: /Users/Delete/5
public ActionResult Delete(Guid id = null)
{
Users users = db.Users.Find(id);
if (users == null)
{
return HttpNotFound();
}
return View(users);
}
//
// POST: /Users/Delete/5
[HttpPost, ActionName("Delete")]
[ValidateAntiForgeryToken]
public ActionResult DeleteConfirmed(Guid id)
{
Users users = db.Users.Find(id);
db.Users.Remove(users);
db.SaveChanges();
return RedirectToAction("Index");
}
protected override void Dispose(bool disposing)
{
db.Dispose();
base.Dispose(disposing);
}
}
}
Thank you!

I've run into similar situations where the default route doesn't handle a path. I've added fallback routes to handle these cases. Try this:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Users",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Users", action = "Index", id = UrlParameter.Optional }
);
}

After a while a figure out something new. If you have errors in your controller (syntax error.. etc) you can get 404 error. If you clear that errors, 404 will be automatically disappear.
