  3. 3. What is anecosystem?
  4. 4. Enterprise App Ecosystem App Hub IT organization Windows Phone 1. Registration 1. Device Enrollment 2. Signing Tools 2. Get apps 3. Cert and Enterprise ID 1. Develop App 2. Package and signRegistration1. Enterprise registers with App Hub 3. App Catalog2. Enterprise downloads app tools3. Microsoft notifies CA of pending 4. Create Token enterprise registration4. Vets enterprise5. CA checks that vetting is complete, and generates a certificate for enterprise
  5. 5. Why ?
  6. 6. Smartphone Market Share Platforms Google Apple Microsoft RIM
  7. 7. Native Wrappers• Phonegap• Titanium• appMobi• Create native apps using HTML5• Provide API’s (Hooks to get out of the sandbox)• Work across platforms (mostly)• Can be submitted to app stores
  8. 8. Cross-Platform Devices• Phones – iOS – iPhone, Touch – Android – Blackberry – Windows Phone 7• Tablets – iPad – Android
  9. 9. Mobile Capabilities That Influence Apps• GeoLocation • Bluetooth• PIM Contacts • Calendar• Camera • Push• Barcode • Screen Rotation• Date/Time Picker • Native Maps• Native Menus • Alert• Tab Bar • Audio File Playback• Navigation Bar • Ringtones• Signature Capture • NFC
  10. 10. Cross-platform frameworks 1. Xamarin 2. Titanium 3. Portable apps 4. AppMobi 5. PhoneGap
  11. 11. Xamarin
  12. 12. Asynchronous code beforeMyApi.OnSomeMethod += () => { InvokeOnMainThread( (result) => { textView.Text = result; });}MyApi.SomeMethodAsync();
  13. 13. async/awaittextView.Text = await MyApi.GetUrlAsync( “http://softserveinc.com”);
  14. 14. С# vs Objective-CObjective-C:// … [button addTarget:selfaction:@selector(touchHandler:) forControlEvents:UIControlEventTouchUpInside];// …-(void) touchHandler:(id)sender { textView.text = @"some text";}
  15. 15. С# vs Objective-CC#:btn.TouchUpInside += (s, e) => { textView.Text = "Clicked!";};
  16. 16. C# vs JavaJava:button.setOnClickListener( new View.OnClickListener() { public void onClick(View v) { textView.setText(“Clicked”); } });
  17. 17. C# vs JavaC#:button.Click += (s, e) { textView.Text = “Clicked!”;};
  18. 18. C# vs {0}• Simply• Cleaner• Develops very quickly• From Java sand pours• [[[[After Objective-C] world : square] as: very] and all: in the colon];
  19. 19. What is Monotouch• Mono framework with AOT compilation for ARM processors and Bindings to Native API• Code is written in C #• UI is native tongue, through C # wrapper• Development environment Visual Studio
  20. 20. Compilation process• Compile your code, libraries, BCL, wrappers over native methods in IL• You can use any language IL• Converted into machine code using AOT compilation• Added to app code with Mono Runtime and everything else
  21. 21. AOT vs JIT• Usually in. Net and Mono native code generated at run - Just In Time compilation• In iOS you can not compile code on JIT, only static linking• But we already know the architecture (ARM) so you can compile the code in advance - Ahead Of Time compilation
  22. 22. Restrictions AOT• No Emit, but remains Reflection• Some specific designs will not work, because compiled on JIT• Generic Virtual Methods – P/Invokes in Generic Types – Some LINQ expressions
  23. 23. Linking• At time of compilation of IL BCL undertakes only code that is actually used• Similarly, you can cut out unused code in their libraries• Need to reduce the size of app
  24. 24. C# API• Subscribe to Events• Setting Properties• Familiar namesvar btn = new UIButton(new RectangleF(0, 0, 200, 80));btn.Enabled = true;btn.SetTitleColor(UIColor.FromRGB(255, 255, 0), UIControlState.Selected);btn.TouchUpInside += delegate { // your code};window.Add(btn);
  25. 25. Wrappers over native methodsMonotouch:• It all comes down to P/Invoke method objc_msgSend with the appropriate parametersMono for Android:• Used JNI (Java Native Interface)
  26. 26. Wrappers over native methodspublic virtual bool Enabled{ [Export("isEnabled")] get { // … returnMessaging.bool_objc_msgSend(base.Handle, UIControl.selIsEnabled); } [Export("setEnabled:")] set { // … Messaging.void_objc_msgSend_bool(base.Handle, UIControl.selSetEnabled_, value); }}
  27. 27. App Structure• Virtually same in native app• AppDelegate, UIWindows, ViewControllers• To describe UI also uses nib files
  28. 28. Development environment – Visual Studio
  29. 29. Cross-platform• Sharing in 30-60 percent of the code• Combining basic mobile functionality• There are various MVVM frameworks Xamarin Titanium PhomeGap Shared Specific Shared Specific Shared Specific
  30. 30. Use of opportunities of Windows OSWin32 APIVista BridgeWindows Bridge.NET Framework – Windows Presentation Foundation – Windows Communication Foundation – Windows Workflow Foundation
  31. 31. Windows 8 platform
  32. 32. Installation Store Apps
  33. 33. Transitions between states App are given several App is not notified seconds to sleep User TerminatedLaunches Low Resources App App App is notified with continued Splash screen App not running
  34. 34. Process isolation

  37. 37. Asynchrony in Windows 8• All that is more than 50 milliseconds – asynchronously• Windows Runtime: IAsyncOperation<T>• JavaScript: Promises• C++: Parallel Patterns Library• VB/C#: async /await
