Linq-to-Entities Left JOIN

Question

This is my query:

from forum in Forums
    join post in Posts on forum equals post.Forum into postGroup    

    from p in postGroup     
    where p.ParentP         


        

Answer 1

 var allforums = from f in context.Fora.Include("Posts")
                           select f;

This query produces the same results as

            var allForums = from f in context.Fora  
                            select new ForumPosts  
                            {  
                                Forum = f,  
                                Posts = context.Posts.Where(x=> x.ForumId == f.ForumId)
