.net - What is your session management strategy for NHibernate in desktop applications?

Question

I find it much more difficult to manage your session in a desktop application, because you cannot take advantage of such a clear bondary like HttpContext. So how do you manage your session lifetime to take advantage of lazy loading but without having one session open for the entire application?
