[Mono-aspnet-list] Fluent NHibernate & Mono 2.8

[Christopher Thielen]

You're right, downgrading to Mono 2.8.1 lets me compile the test application but it still won't run, and trying to compile Fluent NHibernate 1.1 still crashes the compiler. That's not so important to me as simply using Fluent NHibernate.

When I run the test program, it throws an exception:

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

PotentialReasons is empty.

Have you or anybody run into this, or can you run the test application? Are you able to use Fluent NHibernate in your own applications fine?

I've been tasked with learning and using ASP.NET MVC 2 at work and though I've got the basics down, I'm having trouble with some common add-on libraries I'm hoping somebody on the list will know about.
