How to write SQL “not exists” in LINQ

I want to execute the query in sql where i want to get the employees which are not in the department in Dept_id=4,

In SQL

Select emp.ID,emp.First_Name,
from Employee emp
where not exists (select * from Department where Dept_id=4)
order by  emp.ID

In LINQ

var employeesNotEnteredList = (from emps in reslandentity.EMPLOYEE
                                         
                                           where reslandentity.DEPARTMENT.Any(m=>m.Dept_id!=4)
                                         
                                           select emps).Distinct().ToList();

That's it so simple..!!
