使用实体框架6.0.0.0无法连接到ASP.NET MVC中的MySQL
几秒钟前| LINK
你好
我已经尝试了一整夜，将我的ASP.NET MVC项目连接到MySQL数据库，但是没有成功。我在此链接上找到了连接到MySQL数据库（使用MVC 4）的代码
在stackoverflow上。但是我正在使用MVC 5和EF 6进行连接，看来有些不对劲。访问数据库时，引发异常
EntityFramework.dll中发生类型'System.InvalidOperationException'的异常，但未在用户代码中处理
附加信息：未找到具有不变名称'MySql.Data.MySqlClient'的ADO.NET提供程序的实体框架提供程序。确保提供商已在应用程序的“ entityFramework”部分中注册
我连接到我创建的MySql数据库，并在web.config文件上使用了连接字符串。我按照提供的链接指定了web.config。但是我没有设置简单会员资格，因为我目前不需要它。我可以在同一MySQL数据库上使用EF创建具有读写操作的控制器，而不会出现任何问题。我在下面包含了整个web.config（位于项目根目录下的一个）。

最佳答案
您的mysql提供程序名称似乎不正确：
providerName="MySql.Data.MySqlClient"
您应该找到合适的提供商。我建议从mysql网站获取官方提供程序。他们也有EF 6.0的提供者。
