FluentNHibernate.Cfg.FluentConfigurationException

Question

Just some background: it was working code in Production since 2013. Recently added DB password encrypt/decrypt logic in code - compiled code using VS2010 - it's working fine in test but not in Production.

I am assuming it has something to do with configuration xml , mapping or some mismatch of NHibernate dll. Not sure if build/output folders need some thing?

Error in Production:

FluentNHibernate.Cfg.FluentConfigurationException: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.

your production process has already loaded NHibernate from an old (shadow-)cache location then the new dlls are loaded from a new location and try to load their dependencies next to them, but since the process already loaded the assemblies from elsewhere it has a conflict.

You have to try unloading/restarting the AppDomain by restarting the server process, asp.net process, iis, whatever. The error is not related to the code at all.
