Serialize nhibernate entity to json error: Cannot serialize a Session while connected

Question

I'm trying to serialize an nhibernate entity in to json but I always get this error saying Cannot serialize a Session while connected? Does it has something to do with nhibernate proxy?

Yes, this is related to lazy loading. You will need to configure NHibernate to eagerly fetch associations if you want to be able to JSON serialize it. But I would recommend you using view models instead. Ayende Rahien blogged about this issue.
