Can Windows Phone 8.1 application work in Phone 8.0? - windows-phone-8

Is it possible to work application, which developed for 8.1 OS, in Phone which have 8.0 OS?

As far as I know you can't. You could only deploy 8.1 apps on a device which is updated to 8.1. It's just a matter of updating the 8 OS. But after the 8.1 update you could still deploy WP8 apps too.

Can Windows 10 UWP run on Windows 8.1 Devices?

I'm building a Windows 10 UWP app, and would like to know if it will run on Windows Phone 8.1 and/or Windows 8.1 Desktop. Windows 8.1 is still quite prevalent, and I would like to be able to reach these users with my app.
Windows 10 apps can only run on Windows 10 (and newer). If you want to target 8.1, you have to build a 8.1. A 8.1 should run on Windows 10 without any problems.

Any workaround?
WinRT platform is compatible with Windows Phone 8.1 projects. You can copy the sources to your platform specific project and instantiate the connection using SQLitePlatformWinRT class.
