i have tried above given example but i was facing some problem with join keyword that error says:
“The type of one of the expressions in the join clause is incorrect. Type interface failed in the call to ‘Join’.”

but later i tried this below code then its working well….

var joinLinq = from e in db.Emps
join d in db.Depts on e.Fk_Did equals d.Did
select e;

—-
|or|
—-
var joinQuery = from e in db.Emps
join d in db.Depts on e.Fk_Did equals d.Did
select new
{
e.empno,
e.ename,
e.esal,
d.DeptName
};

if anybody facing the same problem, jus go up with this…

Happy coding…!!! :-)
