Answer 1

You have a clash of names as your controller is badly named. Inside your controller called student when you do this:

student student = db.students.Find(id);

You are saying that the variable is a controller, then you try to put your student into it.

The problem should go away if you rename the controller by giving it the Controller suffix:

public class StudentController : Controller { ... }
