错误 - 在EntityFramework.dll中发生类型'System.Data.Entity.ModelConfiguration.ModelValidationException'的异常,但未在用户代码中处理其他信息:在模型生成期间检测到一个或多个验证错误:MVCApplication.Models.Employee :: EntityType"Employee"没有定义键.定义此EntityType的键.员工:EntityType:EntitySet'Employees'基于类型'Employee',没有定义键.

控制器代码:

namespace MVCApplication.Controllers
{
    public class EmployeeController : Controller
    {
        // GET: Employee
        public ActionResult Detail(int id)
        {
            EmployeeContext employeecontext = new EmployeeContext();
            Employee emp = employeecontext.Employees.Single(x => x.Emp_Id ==id);//here its throwing an exception
            return View("employee",emp);
        }
    }

这是我的模范员工类:

namespace MVCApplication.Models
{
    [Table("Employee")]
    public class Employee
    {
        public int Emp_Id { get; set; }
        public string Emp_Name { get; set; }
        public string Designation { get; set; }
        public string City { get; set; } …
