Hi, I have asked the question on this section because I did not find a specific one for windows phone
-Xamarin Forms project (with the lastest XF library)
-WinRT project added to create the background tasks.
-I have modified the manifest on the WP project in order to set the new background task as the tutorials explain.
-My device: NOKIA Lumia 925 - Windows Phone 8.1
When I run my app it works fine, I close it and every 15 minutes a notification is fired. However I reboot my device and the background task disappears. The App was deployed on Release and Debug mode too, I have given permissions to "Run on Background mode event when battery saver is on".
