WL8 equivalent for GetHistoryControlBlock

I have an error with

CODE:
public BarHistory getTickerExterno(BarHistory bars, string ticker, string dataset)
      {
         DataSet ds = DataSetFactory.Instance.Find(dataset);
         GetHistoryControlBlock cb = new GetHistoryControlBlock();
         cb.DataSet = ds;
         BarHistory TickerExterno = WLHost.Instance.GetHistory(ticker, HistoryScale.Daily, DateTime.MinValue, DateTime.MaxValue, 0, cb);
         TickerExterno = BarHistorySynchronizer.Synchronize(TickerExterno, bars);
         return TickerExterno;
      }

I have in my code:

using WealthLab.Backtest;
using System;
using WealthLab.Core;
using WealthLab.Indicators;
using System.Drawing;
using System.Collections.Generic;
using WealthLab.Data;

Please, any help will be appreciated

The equivalent is DataRequestOptions.

1. Since your code already has this using clause...

CODE:
using WealthLab.Data;

2. All it takes to replace GetHistoryControlBlock with DataRequestOptions:

CODE:
public BarHistory getTickerExterno(BarHistory bars, string ticker, string dataset)
      {
         DataSet ds = DataSetFactory.Instance.Find(dataset);
         DataRequestOptions cb = new DataRequestOptions();
         cb.DataSet = ds;
         BarHistory TickerExterno = WLHost.Instance.GetHistory(ticker, HistoryScale.Daily, DateTime.MinValue, DateTime.MaxValue, 0, cb);
         TickerExterno = BarHistorySynchronizer.Synchronize(TickerExterno, bars);
         return TickerExterno;
      }
