When doing a Model -> Generate Change Script and comparing from the model to a sql server 2008 database, the reverse engineering of the sql db does not seem to be able to detect the increment and seed values of a bigint identity primary key field. I have them set at 1,1 in the model and in the database (verified in SSMS table design page), but in the differences window they show as blank on the sql db side and therefore as a difference.
Is this enough info to reproduce?
Also, to confirm, int identity primary key fields work fine i.e. increment and seed are recognised on the sql db side and therefore do not show as differences.
