MySql数据实体EF6中等信任

Question

我们目前通过Hostgator在共享的Windows服务器上。他们正在强制共享服务器在Medium Trust中运行。他们在GAC中有MySql.Data.DLL（6.9.7）。问题是它们在GAC中没有MySql.Data.Entity.EF6.DLL，也不会为我安装它。所以我尝试从gac引用MySql.Data dll，然后从我们的项目中引用MySql.Data.Entity.EF6.dll（6.9.9）。当我这样做时，我收到一个安全错误。我假设这是由于EF6 DLL需要完全信任。对此有何解决方案？感谢

错误：

我不知道你提到的错误。但我建议你仔细阅读本页https://dev.mysql.com/doc/connector-net/en/connector-net-entityframework60.html
您的WebConfig不是格式
