You should also check :

from e in employee
where e.employeeid=10
group e by e.Salary
              into grp
              select new
              {
                  Salary = grp.Key,
                  Count = grp.Count()
              };

Your query puzzles me from the functional perspective: You want to count the number of different salaries for one employee?

Anyway, i think something like this would do also work (untested)

db.Employees.Where(e=>e.id == 10).Select(s=>s.salary).Distinct().Count()
