Windows 10 LiveTile
Windows 10 offers LiveTiles by default as a System Service, so there is not much to do for Implementation. Basically, only the right Feed URL have to be configured, the Widget APIs will handle the Rest.
The most easy Way for Implementing this is to use the uap:TileUpdate Setting in the AppXManifest.xml:
<uap:TileUpdate Recurrence="halfHour" UriTemplate="https://feeds.nexx.cloud/DOMAIN-ID/FEED-HASH?variant=windows&gateway=win8&app=APP-ID&implementation=os&secret=WIDGET-SECRET" />
After that, the Widget is already active and working.
