It looks like MySql needs you to manually open the connection (SQL Server does it automatically for you). You can add a call to this.OpenSqlConnection() somewhere in the data access class. Depending on how pervasive the need is to open the connection manually, you COULD add the code to the connection object's factory method. For example:

public override IDbConnection CreateConnection()
{
	// Create a connection based on the specified Connection string
	MySqlConnection Connection = new MySqlConnection(this.ConnectionString);

	Connection.Open();

	return Connection;
}
