Problem opening Xamarin connection with MySql

I'm a beginner in Xamarin , and I'm having a hard time connecting to MySql . I'm trying to use a simple connection just to test, but it returns an error when I click connect.

Unhandled Exception:

System.TypeInitializationException: The type initializer for 'MySql.Data.MySqlClient.Replication.ReplicationManager' threw an exception. ocorreu.

Follow my code:

namespace MySqlTeste
{
[Activity(Label = "MySqlTeste", MainLauncher = true)]
public class MainActivity : Activity
{

    private Button btnConnect;
    private TextView txtLog;
    MySqlConnection connection;

    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);

        SetContentView(Resource.Layout.Main);

        btnConnect = FindViewById<Button>(Resource.Id.btnCon);
        txtLog = FindViewById<TextView>(Resource.Id.textLog);

        btnConnect.Click += BtnConnect_Click;
    }

    private void BtnConnect_Click(object sender, System.EventArgs e)
    {
        string strConn = "server=10.0.2.2;Port=3306;database=bancoapp;userID=root;password=683122;charset=utf8";
        connection = new MySqlConnection(strConn);
        try
        {
            new I18N.West.CP1250();
            connection.Open();
            if (connection.State == ConnectionState.Open)
            {
                txtLog.Text = "Conexao Executada com Sucesso!";
            }
            else
            {
                txtLog.Text = "Conexao errada";
                connection.Open();
            }

        }
        catch(MySqlException ex)
        {
            txtLog.Text = ex.ToString();
        }
        finally
        {
            connection.Close();
        }
    }
}

The code points the error to the line that is connection.Open();
