EF 配置MySQL

添加 mysql dll 引用

WebConfig 配置：

1.先添加connectionstrings,providerName 换成 mysql的

<connectionStrings>
    <add name="ECSWebDb" connectionString="User Id=xxx;server=.;Database=xxx;pwd=xxx;Persist Security Info=True;"
         providerName="MySql.Data.MySqlClient"/>
  </connectionStrings>

2.EF 添加Provider的 配置
