ORM

For a new big and convoluted project I (am/was) using Devart´s

But today I experienced some inexplicable "object reference not set to
an instance of an object" exceptions or other more specific to this
libraries.
I would wish to change the ORM.
Some experiences would be appreciated. Of course, I prefer open source
software, at least to chase errors thru debugging.

Information that might help folks steer you to alternatives:

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

2) The OS'es involved

3) Are you using any frameworks between the database and the end user?

4) Is an ORM even necessary?

TIA

/C#, from 4.5 framework./

/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.//

/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./

Have you looked at:

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

The best ORM is vanila SQL.

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