NHibernate querying is great – it gives us the ability to query objects directly without the need to know anything about the underlying relational schema. It has a couple of major flaws though: 1. property names are accessed via strings, so we don’t know until runtime whether they exist, or are mapped 2. it’s ugly and cumbersome – frankly probably one of the major barriers I’ve had to ORM until now.
Ayende’s NHibernate Query Generator fixes both of these things. Mapped properties are accessed via properties as nature intended, and querying is a lot easier to read and write. Not quite as neat as Linq-to-NHibernate will be, but so much better than native NHibernate querying that I wonder why it wasn’t included in the trunk.
