Error using MySql connector with Xamarin

Hi,

I am trying to use MySql plugin in Xamarin project.

I have added the pliugin to all my PCL projects and the used:

sql_connection = new MySqlConnection("Server=mysql.mydomain.com; Database=mydb; Uid=myuser; Pwd=mypassword;");

try
{
    sql_connection.Open();
}
catch (MySqlException ex)
{
    DisplayAlert("Error", ex.Message, "Ok");
}

but I am getting below error:

System.TypeInitializationException: The type initializer for 'MySql.Data.MySqlClient.Replication.ReplicationManager' threw an exception. ---> System.TypeInitializationException: The type initializer for 'MySql.Data.MySqlClient.MySqlConfiguration' threw an exception. ---> System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.PlatformNotSupportedException: Operation is not supported on this platform.
