 var preference = (from pre in products

                              orderby pre.PreferenceOrder

                              select pre.PreferenceOrder).Distinct();

            if (preference.Count() > 1)

            {

                var Prefernce = preference.ToList().GroupBy(x => x.PreferenceOrder).OrderBy(x => x.Key).First();

                prod = GetStatusFromProduct(prod.FirstOrDefault()).ToList();

            }

            else

            {

                if (preference.Count() > 0)

                    prod.Add(preference.Single());

                prod = GetStatusFromProduct(prod.FirstOrDefault()).ToList();

            }
