Weirdest problem - catch doesnt work
c#
try
{
    using (var connection = new MySqlConnection("Server=x;Port=3306;Database=x;Uid=x;Pwd=x;Pooling=true"))
    {
        await connection.OpenAsync();
    }
}
catch(Exception ex)
{
    var q2 = "";
}
c#

{
    using (var connection = new MySqlConnection("Server=x;Port=3306;Database=x;Uid=x;Pwd=x;Pooling=true"))
    {
        await connection.OpenAsync();
    }
}
catch(Exception ex)
{
    var q2 = "";
}
x is actually my server's info If my server is running, this works ok. But if I reboot my server, this code throws unhandled exception! Basically catch doesnt work!
