Migrating from Windows Standalone to UWP

Hello!!

I have been struggling with migrating my Windows Standalone app to UWP but all the information is spreaded here ond there and some are out of date.

I was able to build my app for Windows 10 following this steps https://unity3d.com/partners/microsoft/porting-guides , however, I think is a little bit out of date and don't cover some points like "Windows APIs" that I need for my project.

Is there something like an example project out there from Unity or the Windows side or a "Good Practices" guide for UWP?
