我有一个错误

using语句中使用的类型必须可以隐式转换为'System.IDisposable'

在线

using (var context = new EntityContainer())

这是我的代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data.SqlClient;
using System.Globalization;
using System.Data;
using System.Data.Entity;
using school.usi.susibar.model;

namespace school.usi.susibar.test
{
    class Program
    {

        public static void Main(string []args)
         {
            using (var context = new EntityContainer())
            {

                addOrderStatusType(context);

                Console.ReadLine();
            }
        } 


        private static void addOrderStatusType(EntityContainer context)
        {
            try
            {
                OrderStatusType type = new OrderStatusType
                {
                    Name = "Vyrizeno", 
                    CancelPermission = false, 
                    ChangePermission = false
                };
                context.OrderStatusTypes.Add(type);
                context.SaveChanges();
                Console.WriteLine("Pridano"); …
