ADO.NET Entity Framework 实战指南

  Database.SetInitializer(new MyDataInitializer());
  WriteLine("***** Fun with ADO.NET EF Code First *****\n");
  var car1 = new Inventory() { Make = "Yugo", Color = "Brown", PetName = "Brownie" };
  var car2 = new Inventory() { Make = "SmartCar", Color = "Brown", PetName = "Shorty" };
  AddNewRecord(car1);
  AddNewRecord(car2);
  AddNewRecords(new List<Inventory> { car1, car2 });
