Question

我正在使用Visual Studion 2012，MySQL 5.6.14，Connector for .NET 6.7.4和Visual Studio插件1.0.2

我创建了一个实体框架但无法使用“从模型生成数据库”来实现。

我已尝试过此处建议的修改

http://bugs.mysql.com/bug.php?id=67964

但现在我得到了下面的例外（看起来好像凭证没有通过）。有没有人经历过这个？

`Error  2   Running transformation: MySql.Data.MySqlClient.MySqlException (0x80004005): Authentication to host '' for user '' using method 'mysql_native_password' failed with message: Access denied for user ''@'localhost' (using password: NO) ---> MySql.Data.MySqlClient.MySqlException (0x80004005): Access denied for user ''@'localhost' (using password: NO)

根据发行说明，您似乎需要连接器6.8.1。

我能够使用较低版本的连接器将脚本生成模板从SQL更改为MySQL，它包含在MySQL for visual studio插件中。但可能会有一些问题。

MySQL连接器6.7.4实体框架5模型优先
