Accessing lazy-loaded collections/proxies

Are there any recommended patterns on using NHibernate in an ASP.NET Solution?

I am currently using NHibernate in a seperate assembly from my solution, in the assembly I do all my CRUD work. This was working well until I loaded up my database with prod data. The increase in data made the app crawl due to relationships between objects.

I switched to lazy=true and now, of course, I don't have a valid Session why I try to access object.

How have you handled this?

Thanks

You have two options when using lazy-loading :

1- You force the loading of the collections/proxies that you know you will need before closing the session
Example :

Code:

e = session.Load(...);
if(e.MyCollection.Count) {} // after this, the collection is loaded
if(e.MyProxy==null) {} // and here, the proxy is initialized
session.Close();

2- You re-attach the entity to an opened session, using session.Lock(e, None);
