Assembly must be Algo Type when building on VS 2022

Hello Ctrader Team, I'm tring to create a Dll file on Visual Studio 2022 that uses the cAlgo.API in the reference, cause i have multiple functions that need access to some properties like Account, HIstory, Positions and etc, but the thing is that the only error that i get is Assembly must be Algo type. I've made some research but didn't found any solution. I also tried some simple peace of code to what could it be like in this post https://ctrader.com/forum/cbot-support/1739?page=2

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using cAlgo.API;

namespace cAlgo
{
    public class General
    {
        public static int GetPosCnt(Robot robot)
        {
            int iPosCnt;
            iPosCnt = robot.Positions.Count;
            return iPosCnt;
        }

        public static double GetLastCloseValue(Robot robot)
        {          
            return robot.Bars.ClosePrices.LastValue;
        }
    }
}
