C# Exterior Aplicar en LINQ

Question

¿Cómo puedo lograr la aplicación externa en LINQ? Estoy teniendo un pequeño problema.

Aquí está la consulta SQL que estoy usando.

SELECT u.masterID 
     ,u.user 
     ,h.created 
FROM dbo.Users u 
OUTER APPLY (SELECT TOP 1 * FROM UserHistory h where h.masterID = u.masterID ORDER BY created DESC) h 

Answer 1

from u in Users 
join UserHistory on u.masterID equals h.masterID into h 
select new {u.masterID, u.user, h.created.OrderByDescending().First()} 

Answer 2

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() 
} 

O, con una asociación:

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