I have a LEFT OUTER OUTER join in LINQ that is combining with the outer join condition and not providing the desired results. It is basically limiting my LEFT side result with this combination. Here is the LINQ and resulting SQL. What I'd like is for "AND ([t2].[EligEnd] = @p0" in the LINQ query to not bew part of the join condition but rather a subquery to filter results BEFORE the join.
Thanks in advance (samples pulled from LINQPad) -

(from l in Users
join mr in (from mri in vwMETRemotes where met.EligEnd == Convert.ToDateTime("2009-10-31") select mri) on l.Mahcpid equals mr.Mahcpid into lo
from g in lo.DefaultIfEmpty()
orderby l.LastName, l.FirstName
where l.LastName.StartsWith("smith") && l.DeletedDate == null
select g)
Here is the resulting SQL
