SUBSONIC MYSQL SharedDbConnectionScope TransactionScope

The following code works fine in SQLSERVER, but when I change the web.config to work with mySQL after loadbykey , the connection is closed.

is there any configuration in MYSQL to change this?

thanks for any help !!!

    //-----------------------------------------------------------
    string tipoBanco = System.Configuration.ConfigurationManager.AppSettings["tipoBanco"];
    string conexao = System.Configuration.ConfigurationManager.ConnectionStrings[tipoBanco].ToString();

    using (SharedDbConnectionScope scope = new SharedDbConnectionScope(conexao))
    {
        //-----------------------------------------------------------
        using (TransactionScope ts = new TransactionScope())
        {
            Cargo c = new Cargo();
            c.LoadByKey(9999);

            SubSonic.StoredProcedure sp = null;
            sp = new SubSonic.StoredProcedure("sp_test");
            sp.Command.AddParameter("paramTabela", "zzz", DbType.AnsiStringFixedLength, null, null);

            Convert.ToInt32(sp.ExecuteScalar());
        }
    }

      

        
        
        
      

    

web.config
