Incrementally updating an Nhibernate entities values concurrently
===

I'm fairly new to NHibernate - please bear with me. 

So, I have an Nhibernate entity, which is mapped fluently. It has an integer property which I want to increment, and that's it - nothing else is updated etc. 

How can I ensure concurrency when two or more clients are updating the same entity? Does NHibernate take care of this for me out of the box?

Cheers.
