mysql - 部署 - 带有 Entity Framework 的 MySQL

Question

我有一个可以部署的 MVC4 应用程序。该应用程序是数据库优先 Entity Framework ，使用 MySQL 而不是 MSSQL。就调试而言，下面的连接字符串没有错误，但是当我将应用程序部署到 Amazon Elastic Beanstalk 时，它会将我带到登录屏幕，但是当我登录时，它会引发错误:

 Failed to find or load the registered .Net Framework Data Provider.

我不确定为 MySQL 部署配置 web.config 的正确方法是假设 web 配置是问题的开始。关于我遗漏的任何想法？

网络配置:

如果您正在 bin-deploying/xcopying MySQL 的连接器/Net 提供程序，您可能需要将以下片段添加到您的 web.config

<system.data>
  <DbProviderFactories>
    <add name="MySQL Data Provider"
         invariant="MySql.Data.MySqlClient"
         description="Data Provider for MySQL"
         type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data" />
  </DbProviderFactories>
</system.data>
