Hi all.

1) Can anyone explain how to manage NHibernate sessions in Indigo applications. It's so simple to implement session-per-request approach using HttpContext in plain old Web services, but I have no idea about WCF.

2) How to use System.Transactions? Simply use it or something magick required? Could anyone post sample code here?

When we tried using System.Transactions, we ended up with conflicts because the underlying SQL Server connection will implictly join the same transaction scope. We ended up creating our own transaction scope class.

You could also look at the Castle project's NHibernate facility, that provides transaction management:
