c# - 无法从 'System.Data.Objects.ObjectParameter' 转换为 'System.Data.Entity.Core.Objects.ObjectParameter'

Question

在创建 ADO.NET Entity Data Model 时，出现以下错误:

Error 66 Argument 10: cannot convert from 'System.Data.Objects.ObjectParameter' to 'System.Data.Entity.Core.Objects.ObjectParameter' D:\Aziz\Aziz Project\Development\Running Development\Web\pos\pos\Model1.Context.cs 351 278 pos

如何解决这个错误？

Answer 1

using System.Data.Object;
using System.Data.Objects.DataClasses;

Replace for:

using System.Data.Entity.Core.Objects;
using System.Data.Entity.Core.Objects.DataClasses;
