I need some advice on NHibernate Session Management for a C# WinForms application.

I am currently porting an application to use NHibernate. I am also employing a UnitOfWork pattern as described in the link below;

http://nhforge.org/wikis/patternsandpractices/nhibernate-and-the-unit-of-work-pattern.aspx

My question relates to Sessions.

Can you only have one session running per thread at all times?
I have a scenario in which a Session (UnitOfWork) may be open for a form shown by the application but the user opens another form (i.e. Tools - Options) which I would like to have its own UnitOfWork. Clearly in this instance it would make more sense to open another Session for the "Tools - Options" form and not use the currently open session for the underlying form.
Can we have a Dictionary of Sessions on the one thread?

Any advice on session management is appreciated.

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
