I would like to see your experience with popular ORM tools outhere, like NHibernate, LLBLGen, EF, S2Q, Genom-e, LightSpeed, DataObjects.NET, OpenAccess, ...
From my exp:
- Genom-e is quiet capable of Linq & performance, dev support
- EF lacks on some key features like lazy loading, Poco support, pers.ignorance... but in 4.o it may have overcome ..
- DataObjects.Net so far good, althrough I found some bugs
- NHibernate steep learning curve, no 100% Linq support (like in Genom-e and DataObjects.Net), but very supportive, extensible and mature
