A Microsoft platform for building and publishing apps for Windows devices.
My reason for wanting to share settings between individuals is because my app, yMidi Toolbox Plus, allow the user to setup custom MIDI controller setups for controlling musical instruments and music software. Being able to share these configurations between user would be a nice feature.
My app saves to LocalSettings. Ideally I would like to write the settings to an XML or JSON file, something that could be visually inspected and changed if needed.
So far it's looking like I will probably need to roll my own solution.
