This is the "Flowers" sample that I demoed at many conferences around the world. It shows how an application can be "Truly Universal" by running on Windows 10, WPF, Xamarin.iOS, Xamarin.Android, Xamarin.Forms and more. This is also a living sample, to which I regularly add content and features.

Cross platform example with

  • Xamarin.Android
  • Xamarin.iOS
  • Xamarin.Forms
  • Windows 10 Universal
  • Windows Presentation Foundation
  • Window Phone Silverlight 8.1 (Only supported in Visual Studio 2015 and below!!)

This demonstrates a master-detail application with the following features:

  • Master view with:

    • ObservableCollection support
    • Auto-refresh of the list when the collection changes
    • Templated cells
    • (Android) RecyclerView support
    • (iOS) TableView support
    • Databinding support in all platforms
  • Detail view

  • Commenting system

    • Use of commands on all platforms
    • Disabling buttons during asynchronous operations
  • And more...
