I have a MVC 5 app, that has MySQL database hosted in Azure. It was working all well, but today when I tried to type Update-Database and run it, I got the following error message:

What can be the problem, and how can I solve it?

推荐答案

我收到这样的问题：

1：安装更新MySQL连接器到新版本：<一href=\"http://dev.mysql.com/downloads/connector/net/\">http://dev.mysql.com/downloads/connector/net/

1.- Install an update the mysql connector to the new version: http://dev.mysql.com/downloads/connector/net/

2：因为您正在尝试连接到MySQL的远程安装，你必须确保该端口是开放的。您可以尝试连接到本地MySQL数据库来验证这一点。

2.- Because you are trying to connect to a remote installation of MySQL you have to make sure that the port is open. You can try to connect to a local MySQL DB to verify this.

我希望这对你的工作了。

I hope this work for you too.
