1. You can confirm that the your task is registered or not by using powershell. Open powershell with administrative rights, and run 'Get-AppBackgroundTask'. All of registered tasks are listed. If you can't find your task from the list, there are some problems at registration.

2. Have you add the background task project as a reference to your main app?

3. Have you call the BackgroundExecutionManager.RequestAccessAsync()? You should call it before registering, from UI thread.

4. I have a sample app of background task with timetrigger on the store. It's hidden from storefront and search, but you can download it from following link:

https://www.microsoft.com/store/p/ddlgbgtasktrial/9nblggh4s785

This app regist a simple background task with 15min interval timetrigger. This task just output the debugmessage to the logfile. The app shows a log. If it works well, you can see the debug output with about 15min intervals.

I've confirmed that the app works with Win10 desktop 10586.494 and mobile 14393.0.
