            var emp = db.Employees.FirstOrDefault(f => f.Id == model.Id);  
            foreach (var couseid in model.CourseIds)  
                db.EmployeeCourses.Add(new EmployeeCourse { CourseId = couseid, EmployeeId = emp.Id });

Is your project code generated by a predefined template of Entity Developer or written by you manually?
