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

How about..

var result = (from s in context.Shift join es in employeeshift on s.shiftid equals es.shiftid where es.empid == 57 select s)

Edit: This will give you shifts where there is an associated employeeshift (because of the join). For the "not exists" I'd do what @ArsenMkrt or @hyp suggest
