Answer 1

  public override IQueryable FindAll(System.Linq.Expressions.Expression> Id)
        {
            dynamic currentType = Id.Parameters[0];
            var id = currentType.Type.GUID;
            var result = (_uniwOfWork as UnitOfWork).uspGetImages(id.ToString());
            return FindAll();
        }

use keyword dynamic.
