For .Net I know nothing.
For Java, at other side, EclipseLink is fantastic.

Thank you. Do you know about a porting to .NET?

The best ORM is vanila SQL.

Information that might help folks steer you to alternatives:

1) What programming language(s) are you using?

/C#, from 4.5 framework./



Have you looked at:

http://www.npgsql.org/



2) The OS'es involved

/Linux for the database server, Windows for client machines.//
/

//
3) Are you using any frameworks between the database and the end user?
/Yes, a very big one, developed by me (or using open source libraries at 
some spots), which tries to implement MVP pattern. It´s near completely 
agnostic regarding the DAL layer, but I cannot deny that it may be 
somewhat influenced by the Devart´s model.//

/

//
4) Is an ORM even necessary?
/Yes; there are around 50 entities and with lots of foreign keys. It´s 
well worth to have pre-plumbed the code to get "fathers" and "child 
collections". Ah, and I´m working alone./
