I have been trying to track down some sample applications that are using Castle ActiveRecord.
Do you know of any good sample applications?
The biggest problems with Castle Active Record is the lack of basic Examples and the Lack of Documentation. I used it on a project once, and I literally spent about 60% of my time trying to figure out how to do what I wanted to do: googling constantly picking up snippets in blogs here and there....
If you are in the same boat then stop now - NHibernate is a little harder to learn, but you'll get there a lot faster as there is a wealth of information both online and at your local book shop!
