My error is db does not match in the context .How to rectify.

[HttpPost]
public ActionResult Create([Bind(Include = "EmpId,Name,Department,Mobile,Address")] employee Employee)
{
  if (ModelState.IsValid)
  {
    dc.Employees.Add(Employee);
    dc.SaveChanges();

    return RedirectToAction("Index");
  }

  return View(Employee);
}
