The sample apps (for iOS and Android) has two examples:

• a simple text & image download using the new C# 5 async and await syntax.
• another example that shows how to download multiple files in the background and report download progress using IProgress<T>/Progress<T>. It also demonstrates how to cancel the background downloads using a CancellationTokenSource.
