I've been trying for the past several days to get NHibernate working in, well, any form.

I've copied the NHibernate quickstart guide near-verbatim, and I've copied http://www.fincher.org/tips/Languages/NHibernate.shtml verbatim, minus an initialization class.

Everything that I attempt ends up with the prior stack trace - even if it's of a pre-made project that was "working". Exact same error, near-identical stack trace.

Obviously, I'm a flat out newb to this. However, the following code -always- produces this problem, and I have been unable to find any information (Whether it be RTFMing, googling, or searching on these forums) to help out my problem.

Configuration cfg;
ISessionFactory factory;

cfg = new Configuration();
cfg.AddAssembly("Relevant_Text");
factory = cfg.BuildSessionFactory(); <-- Crashing line

Please try
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
instead of
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">

In mappings, replace

with
