some thing like this (I added the Console.WriteLine for debugging purposes)
[Test]
public void try_load_blog_with_posts()
{
Console.WriteLine(">>>>First load...");
using (var session = SessionFactory.OpenSession())
{
var blog1 = session.Get<Blog>(blog.Id);
Console.WriteLine(">>>>>>>>Iterating posts...");
foreach (var post in blog1.Posts)
Console.WriteLine("{0} - {1}", post.Id, post.Title);
}
Console.WriteLine(">>>>Second load...");
using(var session = SessionFactory.OpenSession())
{
var blog2 = session.Get<Blog>(blog.Id);
Console.WriteLine(">>>>>>>>Iterating posts...");
foreach (var post in blog2.Posts)
Console.WriteLine(post.Id);
}
}
here is the implementation of Blog
public class Blog
{
public virtual int Id { get; set; }
public virtual string Author { get; set; }
public virtual string Name { get; set; }
public virtual ISet<Post> Posts { get; set; }
public Blog()
{
Posts = new HashedSet<Post>();
}
}
and of Post
public class Post
{
public virtual int Id { get; private set; }
public virtual string Title { get; set; }
public virtual string Body { get; set; }
}
