C# Outer Apply in LINQ

Question

How can I achieve Outer Apply in LINQ? I\'m having a bit of a problem.

Here\'s the SQL Query I\'m using.

SELECT u.masterID
      ,u.user
      ,h.created         


        

Answer 1

from u in Users 
join UserHistory on u.masterID equals h.masterID into h 
select new {
  u.masterID,
  u.user,
  Created = h.Select(x => x.created).OrderByDescending(c => c).FirstOrDefault()
}

Or, with an association:

from u in Users
let created = u.UserHistories.Select(x => x.created).OrderByDescending(c => c).FirstOrDefault()
select new
{
  u.masterID,
  u.user,
  Created = created
}
