            {
              DbSet.Attach(entityToUpdate.BillingAddress);
              Context.Entry(entityToUpdate.BillingAddress).State = EntityState.Modified;
            }

            if(entityToUpdate.Currency != null)
            {
              DbSet.Attach(entityToUpdate.Currency);
              Context.Entry(entityToUpdate.Currency).State = EntityState.Modified;
            }

            //manual update of  properties
            //Context.Entry(entityToUpdate.BillingAddress).State = EntityState.Modified;
            //Context.Entry(entityToUpdate.Currency).State = EntityState.Unchanged;
        }
