Hi all I recently had a course .Net 3.0 and they couldn't give me a sattisfying answer when I asked 'm what happened to the lease based lifetime management system of .net remoting. They told me service orientation is the way to go nowadays. Can anyone shed some light on this, are the leases/sponsors still there? Is there an alternative? A simple example that safely destroys a WCF CAO would be great. thx in advance
