PROBLEM SOLVED!

PROBLEM WAS: THE HBM.XML FILES WERE NOT SET TO "EMBEDDED RESOURCE".

THANKS ALL!





I've discarded ActiveRecord and ActiveWriter (didn't need GUI and version of writer isn't keeping up with NHibernate's latest).

Now I'm using MyGeneration which seems to be up-to-date in generating both hbm.xml and cs files for each table in my DB.

The program is a simple one-page tester to get started. All I'm trying to do is get started. I want to create a Contact entity/object, set some properties, persist the object to the DB. Then I'm trying to read it back.

Here's the documentation for v2.0 that I believe I'm following to the letter:
http://nhforge.org/doc/nh/en/#quickstart-intro

Does anyone just have a working example for NH v.2.0.1GA (in C# / ASP.NET) they could share or point me to one?

Thanks for any assistance.



The error and details follow. The only "Reference" in my project beyond the regular "System" ones added when creating a VS2008 project is 'NHibernate". Do I need others?

Documentation for 2.0 doesn't say anything about using AddAssembly, AddClass, or AddFile. I believe I've followed it to the letter.

Also, I'm using the hibernate.cfg.xml because the documentation's details don't seem to work in web.config. For example...

The documentation for 2.0 has:

<configSections>
<section
name="hibernate-configuration"
type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"
/>
</configSections>

I tried using this and got:

"Configuration Error

Parser Error Message: An error occurred creating the configuration section handler for hibernate-configuration: Could not load file or assembly 'NHibernate' or one of its dependencies. The system cannot find the file specified.
