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?
/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./
TIA
