无法加载文件或程序集’MySql.Data

我正在开拓ASp.net mvc 5中的应用措施并行使代码优先要领.

当我实行启用迁徙时,它会抛出一个错误.我在参考文献中找到了MySQL.Data.dll.也许是什么题目？

我上传了source at here.

假如也许的话,请指导我.感谢

错误在下面提到;

版本配置为6.9.3.0但在bin文件夹文件中MySql.Data.dll和MySql.Data.Entity.EF6.dll的版本为6.8.3.0
修改您的Web设置以行使正确的版本或从packages文件夹更新您的dll.
您的题目的来源是,当您行使nuget安装MySql.Data.Entities时,它将旧版本的MySql.Data替代为较新版本,但Web设置保持稳固.
