Understanding the Temphire

[ganySA]

Hi

I am looking through the example to try and understand a few of the concepts being used:
EntityManagerProvider

1. registerAnnotations: what does method do? - I have some annotations on my .net core entity objects and i was under the impression breeze automatically added these validations?
2. ignoreForSerialization - what is this method for?Is this to ignore additional fields that are added to the local model for serialization purposes?

I am trying to understand how the unit of work 'works':

1. It makes a copy of the primary entity manager
2. Then you make your changes to that manager (add/edit/delete) and save changes.
3. Is the original entity manager there simply there to provide a base with lookup tables for other 'units of work'?

Thanks.
