1. Hot Tuna CROSS PLATFORM DEVELOPMENT WITH.NET, XAMARIN AND MVVMCROSS

3. To cover What are we trying to achieve Example Theory (boring!) Getting started with MvvmCross Plugins Platform specific stuff Summary Links

4. The holy grail

5. What is achievable

6. Example – Lions Official (sorry)

8. The pieces. net (duh) Xamarin (iOS, Android, Mac) Portable Class Libraries MvvmCross

9. Xamarin Commercial products for C# development for non-Windows platforms Xamarin.Android Xamarin.iOS Xamarin.Mac Need business edition for VS integration @ $999 US each

10. Xamarin Demo

11. Portable Class Libraries Create a single library that can be used by multiple.net frameworks Allows access only to functionality shared by all selected frameworks Does some nifty namespace mapping Makes cross platform development much easier Microsoft and 3 rd party PCLs available (HttpClient, Imaging, JSON…)

12. .net x.x Portable Class Library Shared functionality Silverlight

13. .net x.x Windows Store Portable Class Library Shared functionality Silverlight

14. .net x.x Windows Store Portable Class Library Shared functionality Silverlight Xamarin.XXXX

15. PCL Demo Easy-peasy, lemon squeezy It’s hard to find a good image of a class library

16. Mvvm: Model – View Model - Model

17. Mvvm: Key interfaces INotifyPropertyChanged RaisePropertyChanged(() => PropertyName ); ICommand INotifyCollectionChanged (or ObservableCollection)

18. Mvvm: Binding

19. XAML Code <Button Content="Go Second" Command="{Binding GoSecondCommand}" /> public class FirstViewModel : MvxViewModel { private string _hello = "Hello MvvmCross"; public string Hello { get { return _hello; } set { _hello = value; RaisePropertyChanged(() => Hello); } } public System.Windows.Input.ICommand MyCommand { get { return new Cirrious.MvvmCross.ViewModels.MvxCommand(DoMyCommand); } private void DoMyCommand() { Hello = Hello + " World"; } public System.Windows.Input.ICommand GoSecondCommand { get { return new Cirrious.MvvmCross.ViewModels.MvxCommand(DoGoSecond); } private void DoGoSecond() { ShowViewModel (); }

20. MvvmCross Cross Platform MVVM Development Framework Free, open source Supports WP7,8 WPF WinRT Xamarin.Android Xamarin.iOS Xamarin.Mac AKA Mvx

21. MvvmCross Architecture

22. Using MvvmCross Hard -download from github, compile, include references etc Easy-Nuget; look for MvvmCross Hot Tuna Starter Pack, and plugins Real Easy-NinjaCoder

23. Getting started - Nuget

24. Getting started - NinjaCoder

25. Plugins Convenient way to access platform functionality Use NinjaCoder or Nuget to add plugins Includes Accelerometer, Email, Files, Location, Messaging, Sqlite 3 rd party plugins available as well. Consume plugins using Dependency Injection or Service locator

26. Plugins Demo

27. Platform specific code Describe functionality using an interface in.Core Create platform specific implementation in.xxxx Register implementation on app startup ◦Mvx.RegisterSingleton (new SettingsPersistanceWPF()); ◦Mvx.RegisterType (); Consume plugins using Dependancy Injection or Service locator persistance = Mvx.Resolve ();

28. Platform specific example Here is one that I prepared earlier

29. Summary PCLs let you use easily share code across multiple platforms Xamarin lets you use C# on Android, iOS and Mac MvvmCross wraps it all up to make it easy Shared PCL that holds most functionality Platform specific apps for views and dependant code Plugins let you easily add functionality in a cross platform friendly way Do your own platform dependant stuff using interfaces and IoC/Dependancy Injection
