Cannot compile code from documentation in Visual Studio 2022

Hi,

I copied some code from https://help.ctrader.com/ctrader-algo/guides/trading/#getting-information-on-deals   . Now when I build using embedded cTrader compiler it will succeed. But when I proceed to build in Visual Studio 2022, the compilation failed. It gave following errors…

'Position' does not contain a definition for 'Deals' and no accessible extension method 'Deals' accepting a first argument of type 'Position' could be found (are you missing a using directive or an assembly reference?) 

'History' does not contain a definition for 'FindByPositionId' and no accessible extension method 'FindByPositionId' accepting a first argument of type 'History' could be found (are you missing a using directive or an assembly reference?)

How do I solve this problem?

using System;
using cAlgo.API;

namespace cAlgo.Robots
{
    [Robot(AccessRights = AccessRights.None)]
    public class DealsExample : Robot
    {
        protected override void OnStart()
        {
            var position = ExecuteMarketOrder(TradeType.Buy, "EURUSD", 10000);

            var deals = position.Position.Deals; // ERROR HERE 

            foreach (var deal in deals)
            {
                Print(deal.ExecutionTime + " " + deal.Status + " " + deal.Id);
            }

            ClosePosition(position.Position, 3000);
            ClosePosition(position.Position, 7000);

            var closing_deals = History.FindByPositionId(position.Position.Id); // ERROR HERE

            foreach (var closing_deal in closing_deals)
            {
                Print(closing_deal.ClosingDeal.ExecutionTime + " " + closing_deal.ClosingDeal.VolumeInUnits);
            }
        }

        protected override void OnStop()
        {
        }
    }
}
