fluentnhibernate and virtual entities

Why f开发者_开发问答luentnhibernate (v. 1.0) when you map the entities (not using automap), all must be virtual, even those that are not mapped? There is a way not to set props / methods virtual ?

This is not a FluentNHibernate's requirement but rather NHibernate's. It is because when a property is marked as virtual features such as lazy loading are possible. There's a blog post describing the details behind this.
