"The system cannot find the file specified." in asp.Net MVC

Question

I have created asp.Net MVC application (code first approach). If I run Index.cshtml file, then it arises following error message in the browser.

"The system cannot find the file specified"

Error Shows in this line

Line 26: db.Standards.Add(standard1);

If it runs successfully, then it must create Database in App_Data folder. But this Index.cshtml is not running successfully. Please guide that how to resolve this problem.

In Visual Stusdio 2015->File->New->Project->Asp.Net Web Application, Name of Project:Note7Page55->Seelect MVC option->ok.

 

Model Folder->Student.cs

namespace Note7Page55.Models
{
    public class Student
    {
        public int StudentId { get; set; }
        public string StudentName { get; set; }
        public string Address { get; set; }
        public string City { get; set; }
        public Standard Standard { get; set; }
    }
}

Model Folder->Standard.cs

using System.Collections.Generic;
namespace Note7Page55.Models
{
    public class Standard
    {
        public int StandardId { get; set; }
        public string StandardName { get; set; }
        public ICollection<Student> Students { get; set; }
    }
}

Model Folder->SchoolContext.cs

using System.Data.Entity;
namespace Note7Page55.Models
{
    public class SchoolContext : DbContext
    {
        public SchoolContext() : base(){}
        public DbSet<Standard> Standards { get; set; }
        public DbSet<Student> Students { get; set; }
    }
}

Controller Folder-> SchoolController.cs

using System.Web.Mvc;
using Note7Page55.Models;
namespace Note7Page55.Controllers
{
    public class SchoolController : Controller
    {
        SchoolContext db = new SchoolContext();
        // GET: School
        public ActionResult Index()
        {
            Standard standard1 = new Standard()
            {
                StandardName = "Std. 5th"
            };
            Student student1 = new Student()
            {
                StudentName = "Dinesh Kudale",
                Address = "Gar Fata",
                City = "Patas"
            };
            db.Standards.Add(standard1);
            db.Students.Add(student1);
            db.SaveChanges();
            return View();
        }
    }
}

Added View as Index.cshtml

@model Note7Page55.Models.Student

@{
    ViewBag.Title = "Index";
}
<h2>Index</h2>

 When I run Index.cshtml file, then it arises following error message in the browser.

"The system cannot find the file specified"

Please guide that how to resolve this problem.
