In your docs it says you have support for NewSequenceid(), well there is no NewSequenceid(), or at least i cant find it , it should be NEWSEQUENTIALID()

and the support doesnt seem to be working

After i save an entity, it wont refetch it.

EDIT: Well i found the problem/answer, but in the changes docs the spelling is still wrong

I made this mistake a lot, sorry about that. Indeed: NEWSEQUENTIALID(). I'll fix it
