Cannot evaluate expression because the code of the current method is optimized

Hi,

I'm trying to debug an indicator within Visual Studio but am receiving 

Cannot evaluate expression because the code of the current method is optimized

when trying to access IndicatorDataSeries results.

A simple example is below.

Should I be able to view the values within IndicatorDataSeries?

Thanks

using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
using cAlgo.Indicators;

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewIndicator : Indicator
    {
        [Output("Main")]
        public IndicatorDataSeries Result { get; set; }

        private MarketSeries daily;

        protected override void Initialize()
        {
            daily = MarketData.GetSeries(TimeFrame.Daily);
        }

        public override void Calculate(int index)
        {
                Result[index] = daily.Close.LastValue;
        }
    }
}
