왼쪽 entityframework

Question

내가 LINQ와 왼쪽 쿼리를 만들려고 노력과 LINQ에 가입?

참고 :

var query = (from m in context.Mutatie 
         join d in context.tblDienstverband on m.fkDienstVerbandID equals d.DienstverbandID into grp 
         from d in grp.DefaultIfEmpty() 

         join med in context.tblMedewerker on d.fkMedewerkerID equals med.MedewerkerID into grp1 
         from med in grp.DefaultIfEmpty() 

         where med.fkMedewerkerID == this.klantId 
         select new { m, d, med }); 
      return query;
