Is UnitOfWork all or nothing - v8.0.1?

The UnitOfWork is atomic and it will therefore reroll the database transaction used to store the data if an error occurs.

You can use the <iEntity).Save method, without using the UnitOfWork, if you want to have each save operation as an atomic operation. But this might give you a performance penalty, as bulk processing is not available then.

Thanks Markus, I found this:

uow.ContinueOnError = True

Would this still save all objects which it can? I would test it myself but unfortunately won't get a chance until early next week so I'm being a bit cheeky and asking here

No, it will not. If you choose to set ContinueOnError = True, the UnitOfWork is not throwing an exception when an error occurs. Instead, you need to check the Invalid property. If the property is true, then an error had occurred and the UoW had already written out some DML (Data Manipulation Language) aka SQL code. You would need to throw an exception in that case to initiate the rollback of the underlying transaction of the UoW.
