TaskCloud

Contains THREE different 'cloud-based' todo list examples, an example using Dropbox's Datastore API, a cross-platform Azure example and the Apple-specific iCloud:

Dropbox (Xamarin Component)

You can read about the support for Dropbox's latest Datastore API in Xamarin's blog post.

Azure (Xamarin Component)

A Xamarin.iOS example built for this introductory Azure Web Services YouTube video.

There is also a Xamarin.Android version (no accompanying video... yet)

The other Azure example (below) uses Json and the REST web service directly.

iCloud

This sample demonstrates how to subclass UIDocument in iOS5 using MonoTouch, and access the files via iCloud.

NOTE: you need at least two devices with the same App Store login to play.

It is still a work-in-progress. It shows how to subclass UIDocument to provide a way to read/write files to the iCloud data store and query that datastore.

The TaskDocument:UIDocument subclass creates a .task file for each 'task item'. These are saved-to and read-from the iCloud UbiquitousDataStore (see NSFileManager.DefaultManager.GetUrlForUbiquityContainer).

Other features of iCloud such as conflict resolution and moving to/from local storage have NOT been implemented.

Azure (first principles)

Basic usage of Microsoft's Azure Mobile Services REST API. Accesses the REST service directly. Purely provided as an example of making it work - not necessarily ready for a production implementation - wait for the official toolkit!

This app works against the same database that you create in Microsoft's Windows 8 example, so you end up with multiple devices/platforms all sharing the same TodoList on the Azure server.

There are two example projects:
