Select data from multiple table with Entity Framework - asp.net

Question

I am able to select data from two tables, But I am getting partial result only while retrieving data from three tables.
var items = from orders in nobleappDbContext.JobOrders.Where(m => m.OrderStat == 0)
join users in nobleappDbContext.users on orders.Uid equals users.Uid
join customers in nobleappDbContext.customers on users.Uid equals customers.Uid into customdata
from m in customdata.DefaultIfEmpty()
select new
{
Eid = orders.Eid,
Uid = orders.Uid,
OrderStat = orders.OrderStat,
Name = m.Name,
Contact = (m.Contact == null) ? 0 : m.Contact
};
return Ok(items);
With this code, I am getting only result (common result) from users table and I am looking for something like UNION or OUTER JOIN.
Any help will be highly appreciated

Answer 1

finally I got exactly what I was looking for, here by posting the answer as I might help someone looking for same. LEFT JOIN with Entity Framework is the key
var query = from a in authurs
join b in books on a.Id equals b.AuthorId into auth_books
from left in auth_books.DefaultIfEmpty()
join bs in booksSeries on left.BookSeriesId equals bs.Id into books_bookseries
from left2 in books_bookseries.DefaultIfEmpty()
select new
{
Author = a.Name,
Book = left.Name,
BookSeries = left2.Description
};
var resList2 = query.ToList();
