Add CalDav based Sync Service #16
Description
Background:
With some kind of your "own" server, something simple like a NAS or Raspberry, it is pretty easy to host your own Calendar Server. For example with the build-in Calendar in Synology DSM, via OwnCloud, NextCloud etc. Those calendars also support "Tasks". Those Tasks are similar to Calendar events in that they can be synched via CalDav. For example I use DavDroid + OpenTasks to get those on android device.
What's missing is a Windows Client for that. And I think the 2Day App on Windows would be a great candidate to implement the CalDav connection.
Personally, I have limited UWP dev experience but would not mind looking into this myself. Where would one start with such a task? Seeing that 2Day supports several backends I assume there is a kind of interface, common to all of them, to be implemented?
