You do this by right clicking on the relationship connector, and selecting "Make subclass" from the popup menu.

I've been trying it with NHibernate 1.2 RC1. Not much luck. Then again, it could just be me. http://ayende.com/2240/nhibernate-code-generation#comment3http://ayende.com/2240/nhibernate-code-generation#comment3Fri, 23 Mar 2007 04:03:11 GMTI'd also recommend looking at Codus NHibernate template. It not only generates all the classes and hbm files, but also a set of unit tests: http://www.adapdev.com/codus http://ayende.com/2240/nhibernate-code-generation#comment2http://ayende.com/2240/nhibernate-code-generation#comment2Thu, 22 Mar 2007 13:17:19 GMTHow does it handle sub-classes? http://ayende.com/2240/nhibernate-code-generation#comment1http://ayende.com/2240/nhibernate-code-generation#comment1Tue, 20 Mar 2007 18:29:37 GMT
