How to SELECT WHERE NOT EXIST using LINQ?

Question

I have to list all \"shift\" data to be assigned to an \"employee\" but shift data must not be included if it is already existing in employ

Answer 1

The outcome sql will be different but the result should be the same:

var shifts = Shifts.Where(s => !EmployeeShifts.Where(es => es.ShiftID == s.ShiftID).Any());
