Lambda LINQ is still a link expression. However, the statement should look something like this:
var train2 = (from c in db.sample1
join t in db.sample2
on c.CertificateId equals t.CertificateId
where c.Year.Value.Year == year && c.TrainingTypeId.Value == trainingTypeId
&& c.IsApproved.Value && t.EndDate >= DateTime.Now
select c).Distinct();
