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