        // To protect from overposting attacks, please enable the specific properties you want to bind to, for

        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Create([Bind(Include = "ID,NAME,LASTNAME")] Teachers teachers)
        {
            if (ModelState.IsValid)
            {
                db.Teachers.Add(teachers);
                db.SaveChanges();
                return RedirectToAction("Index");
            }

            return View(teachers);
        }

        // GET: Teachers/Edit/5
        public ActionResult Edit(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            Teachers teachers = db.Teachers.Find(id);
            if (teachers == null)
            {
                return HttpNotFound();
            }
            return View(teachers);
        }

        // POST: Teachers/Edit/5
        // To protect from overposting attacks, please enable the specific properties you want to bind to, for 
        // more details see http://go.microsoft.com/fwlink/?LinkId=317598.
        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Edit([Bind(Include = "ID,NAME,LASTNAME")] Teachers teachers)
        {
            if (ModelState.IsValid)
            {
                db.Entry(teachers).State = EntityState.Modified;
                db.SaveChanges();
                return RedirectToAction("Index");
            }
            return View(teachers);
        }

        // GET: Teachers/Delete/5
        public ActionResult Delete(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            Teachers teachers = db.Teachers.Find(id);
            if (teachers == null)
            {
                return HttpNotFound();
            }
            return View(teachers);
        }

        // POST: Teachers/Delete/5
        [HttpPost, ActionName("Delete")]
        [ValidateAntiForgeryToken]
        public ActionResult DeleteConfirmed(int id)
        {
            Teachers teachers = db.Teachers.Find(id);
            db.Teachers.Remove(teachers);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        protected override void Dispose(bool disposing)
        {
            if (disposing)
            {
                db.Dispose();
            }
            base.Dispose(disposing);
        }
    }
}

and then created views (index,create,delete,insert) with that controllers the problem is when i navigate to localhost/Teachers/Index . the page load forever and nothing to show . and when manually create another controller base on another model it was worked fine. where is the problem ???

Does db.Teachers.ToList() return anything, or do you get already a timeout there ? — C0d1ngJammer, Feb 14 '17 at 08:40

I think check your connection string. You can put breakpoint in index action method of TeachersController and see that you are getting the teacherlist. Most probably the error will be of connection to database. You can try by changing

return View(db.Teachers.ToList()); to just return View();

and on view just write plain html.

They look normal and seem to be generated by MVC. You should put a breakpoint in the "Index"-Method (Action) of "TeachersController" (Controller) and debug db.Teachers and tell us if it does have any values or exceptions – C0d1ngJammer Feb 14 '17 at 12:31
The database are different for both the connection string you can try by creating the object of TeacherContext so you can change the code in TeachersController class from "private MyDemoContext db = new MyDemoContext();" to "private TeacherContext db=new TeacherContext();" – Engineer Feb 15 '17 at 11:19
