Answer 1

Try following

    return _ctx.Notes.Select(r => new NoteBrief
    {
        Id = r.Id,
        Title = r.Title,
        Created = r.Created,
        ParentNoteId = r.ParentNoteId,
    }).OrderBy(x=>x.Created).GroupBy(x=>new {Id=x.Id, Title=x.Title}).Select(x=>x.First()).AsQueryable();

}
