*Post will be updated with explanation soon!*
The following samples have been tested on Desktop, Mobile and IoT (Raspberry Pi 2). They require that you have the 10586 SDK installed (Visual Studio 2015 Update 1 or later).
UWP using Entity Framework 7 – use SQLite for persistent storage: EF7Sample
UWP using SQLite-NET, second example using SQLite-WinRT NuGet.
The SQLite-NET sample also demonstrates accessing a SQLite database from a background task (Click the Background Task link on the command bar menu to navigate to a page where you can register and signal (i.e. start) the background task).
*Check the SQLite Extension SDK references in the foreground projects. The samples were built with 3.10.0 but if you have a different SQLite version installed, you will need to remove and then re-add the SQLite extension reference*
