Hi, I am creating a windows application which is communicating with a central database. But I need a local database too, which can store the application's data if the laptop is not connected to the network and the central database is not reachable. I also want the local database to sync with the central database as soon as a connection is established.

What I have tried:

I tried connecting the application with the central database and it worked seamlessly. But I couldn't find out how to create two databases and attach them user wise.

That's because it's not trivial, not at all.
You have a lot of reading to do: Introducing the Microsoft Sync Framework: Next Generation Synchronization Framework[^] is a good start.

Hi, Is it possible MS no longer supports this: https://stackoverflow.com/questions/49149511/is-microsoft-sync-framework-alive

Yeah, they are apparently trying to push everyone to "Always On" via Azure, so support stopped a while ago.
Still works, though, apparently.
I've started looking at this:
(Better link): https://ampliapps.com/sqlite-sync/

(Original link): https://github.com/sqlite-sync/SQLite-sync.com
Which provides local / bidirection sync and is open source - but I've got little time to look at it in depth - there are a few projects I'd like to move to replication but keep putting off. Gotta bite the bullet sometime, but ... you know how that one goes, Bill!
