Configure NHibernate to compile mappings "on the go"

Question

By default, NHibernate compiles the mappings when creating the SessionFactory...

Is it possible to configure NHibernate so that it compiles the needed mappings "on the go"? So that it only compiles a mapping when it needs it?

The reason I'm asking is to work around the lenghty operation on start-up (of a winforms, well, AutoCAD application...)

Answer 1

You can't add mappings to an existing session, you can only instantiate a new Session. A similar question was asked and answered here: http://stackoverflow.com/questions/702195/

Answer 2

Not possible. A good way to speed up session factory creation is serializing/deserializing the configuration object to a file.

Here are some more ideas to speed this up (or at least reduce the perceived startup time)
