entity framework - Linq return child entities not used in parent entities -

-

i have case whereby have following entities in model.

public class permission {    public int id { get; set; }    public operation operation { get; set; }  }   public class operation  {    public int id { get; set; }    public string name { get; set; }  }

the way repository set need query operationrepository find operations have not been used in permission. ef operation entity has navigation property permissions entitycollection below:

public partial class operation : entityobject {     public entitycollection<permission> permissions     {         get; set;     } }

the method in operationrepository is:

public ienumerable<ioperation> findunassigned() {     //query here }

filter operations navigation property `permissions doesn't have elements

.where(p => p.permissions.count() == 0)
