SecurityException
我们在 godaddy 上使用实体框架时得到了一个。该实体已针对 MySQL 存储进行配置。(v. 6.1.2)虽然异常有点奇怪......查看异常堆栈似乎意味着如果我们在站点的任何位置打开与 MySQL 的连接,那么我们应该得到相同的异常;但是,直接打开 MySQL 连接似乎在站点的另一部分工作......
这是验证:
using (MySqlConnection connection = new MySqlConnection(ConnectionString))
{
connection.Open();
...
}
有人遇到类似的问题吗?
完整的错误堆栈跟踪如下:
