I worked with an SQLite Database on a personal C#/WinForms app. It was a bit complicated to get started, but afterwards, what a handy trick in comparison to using something like the discontinued SQL Server Compact.

I did, however, "enhance" it a bit (or "proprietarize" it) by encrypting it with a short password and an AES algorithm with some uncommon settings. I never shipped it that way, but the output file looked like any other proprietary app's file - a mess of random symbols.
