linq to sql recursive query

Question

EmployeeId  Name  ManagerId
------------------------------
1           A     null
2           B     null
3           C     1
4           D     3
5           E     2
         


        

Answer 1

var managedEmployees = ctx.Employess.Where(x => x.ManagerId = 4).AsEnumerable()

If you want the whole tree at once, the solution is more complex. In SQL its best done with an CTE, I don't know if EF can handle this using linq- more likely an iterative solution would be used.
