Error is here

        public string IPMKodu { get; set; }
        public int StokGroupId { get; set; }
        public StokGroup StokGroup { get; set; }

        public List<StokCard> StokCards { get; set; }

public class StokCardAdditionalFeatureValue:BaseModel
{
        public int StokKartId { get; set; }
        public StokCard StokCard { get; set; }
        public int GroupFeatureId { get; set; }
        public GroupFeature GroupFeature { get; set; }
        public string FeatureValue { get; set; }
}

Answer 1

Starting from StokCardAdditionalFeatureValue we have at least two cascade paths:

Through GroupFeater property and then we have reference to StokGroup

Through StokCard and then through StokGroup

You need to verify and clean up your database design to not cause such cycles.
