Any body using NHibernate? So far I like it, but it honestly doesn't feel stable. When running tests, sometimes (sometimes!) the queries that ran fine just before bomb out with Message: expected in: <end-of-text> The query executed was "from prf_ProfileSection"... not much else to screw up here, yet the parser fails. Then, I recompile the DLLs and run and it works again... Anyhow, the main question for this blog post is what's your favorite OR/M and how flexible and stable is it...
