entity framework in .net 3.5 doesn't offer left join in linq queries. the way to get "joined records" is through navigation property between entities
from here: left outer join in entity data model asp.net
score:1
you need to use defaultifempty()
for an outer join:
from ta in context.test_attempt
join uf in context.user_flag on ta.users.userid equals uf.userid into g
from uf in g.defaultifempty()
select new { ta, uf }
your outer from/select above is unnecessary, just project ta
and uf
into what you need.
