无法使用实体框架6.0.0.0

Question

无法使用实体框架6.0.0.0

几秒钟前连接到MySQL在ASP.NET MVC连接到MySQL在ASP.NET MVC | LINK

喜，

我已经尝试通宵连接我的ASP.NET MVC项目到MySQL数据库，但我不成功。我发现代码连接到这个链接上的MySQL数据库（使用MVC 4）

在stackoverflow上。不过，我正在使用MVC 5和EF 6来连接，似乎有什么不妥。当访问数据库时，会抛出异常

“System.InvalidOperationException”类型的异常出现在EntityFramework.dll但在用户代码中没有处理 其它信息：没有实体框架提供发现ADO.NET提供程序用不变的名字'MySql.Data.MySqlClient'。确保提供程序在应用程序的'entityFramework'部分中注册

我连接到MySql数据库我已创建并使用web.config文件上的连接字符串。我按照我提供的链接指定了web.config。但我没有设置简单的会员，因为我目前不需要它。 我能够在同一个MySQL数据库上使用EF创建一个读写操作的控制器，而且没有任何问题。下面列出了我的整个web.config（项目的根目录下）。

Answer 1

为MySQL提供你名字似乎不正确：

providerName="MySql.Data.MySqlClient" 

你应该找到合适的供应商。我建议从MySQL网站获得官方提供商。他们也有EF 6.0的提供者。
