Does Project Wonder also have a replacement for EOSharedEditingContext??
Project Wonder's replacement is "don't use it" ... So no.

Err .. no -- come on, be fair -- this is not true. It's just that most people don't use it == scared of it == don't use it because of misinformation.

Are there any issues if the WO version is used?

No. None.

I have, however, subclassed it recently to extend its core functionality. i.e., mine (which I'm happy to contribute to Wonder) enables it be treated like a regular ec -- so you don't have to think about bind* and refreshing etc -- and as such creates a unique key from an EOFetchSpecifcation which can be matched again the next time the same query is performed.

As such, the fetch results themselves are cached automatically and I'm using the timestampLag to determine when to return the same results or when to refresh the query.

Oh, and it also invalidates inverse relationships so that they're updated properly.
