Ayende also announces the RTM of NHibernate Linq 1.0 – this is fantastic news!
A couple of items with NH Linq to keep in mind:
This Linq release support just about anything that you can do with the criteria API. We do not support group joins or subqueries in select clauses, since they aren’t supported by the criteria API. NHibernate’s Linq support has been tested (in production!) for the last couple of years, and most people find it more than sufficient for their needs.
As FYI, NHibernate.Linq includes the NHibernateContext class that supports the IUpdateable and IExpandProvider interfaces required by ADO.NET Data Services (thanks Shawn)
