Question

我正在尝试将.NET Web服务从MsSql迁移到MySql。我按照本教程中的步骤使MySql正常工作：https://dev.mysql.com/doc/connector-net/en/connector-net-entityframework60.html

将MsSql数据库结构和数据转换为MySql数据库。

当我尝试通过Entity（例如db.Languages.FirstOrDefault()）从MySql数据库获取数据或尝试使用程序包管理器控制台（例如Update-Database）执行任何操作时，我总是遇到此异常：< / p>

System.Resources.MissingManifestResourceException: Could not find any resources appropriate for the specified culture or the neutral culture.  Make sure "MySql.Data.Entity.EF6.Properties.Resources.resources" was correctly embedded or linked into assembly "MySql.Data.Entity.EF6" at compile time, or that all the satellite assemblies required are loadable and fully signed.

我删除了所有迁移和__MigrationHistory表。

Visual Studio 2015 ,. NET 4.5.2，EntityFramework 6.2.0，MySql.Data.Entity.EF6 6.10.7.0，MySql数据库版本：5.6.15。

请帮我解决这个问题。谢谢！

将MySql.Data.Entity从6.10.7降级到6.9.12“解决了”这个问题。
