I have a website I developed using NHibernate and it works great. I recently also created a windows service which utilized NHibernate. I'm new to NHibernate (about 6 months) so the whole cache thing has thrown me for a loop. I noticed that changes that were being made to the database outside of my windows service didn't show up when I grabbed a bunch of objects that I thought were being pulled from the database. Thus I learned about first-level cache.

I really don't want to completely rewrite my fabulous Domain-Driven Designed system to accomodate something that is considered a feature in NHibernate but it is causing me issues with other programs that access the database beside my own. I looked at using the IStatelessSession but it didn't seem to support some stuff that the I'm using in ISession so I would rather stay where I am with that.

How else can I force NHibernate to always go grab from the database? I'm using code from "NHibernate with ASP.Net Problem-Design-Solution" to implement my DDD.

I suppose the easiest way is to use a new session every time you read from the database or to clear the session after reading.
