- 1. Oliver Scheer Senior Technical Evangelist Microsoft Deutschland http://the-oliver.com Introducing Windows Phone 8 App Development
- 2. Agenda Introducing Windows Phone 8 New app platform in WP8 Application development models WP8 version of WinRT Supported application models Getting started with WP8 app development New features overview Using the Windows Phone Developer Tools WP7x compatibility
- 3. New WP8 Hardware Beautiful new hardware from Nokia, HTC, Samsung and more…
- 4. New multicore chipset New graphics processor Increased RAM: 1GB or 512MB More Screen resolutions Removable, encryptable storage NFC Modern Smartphone Platform
- 5. Windows 8 and Windows Phone 8 Share Many Components At The Operating System Level Shared Windows Core Windows KernelWindows KernelWindows NT Kernel OS Modules
- 6. • Shared Core means • OS components such as the kernel, networking, graphics support, file system and multimedia are the same on both Windows 8 and Windows Phone 8 • Hardware manufacturers work with the same driver model on both platforms • Windows Phone gets the support for multi-core and other hardware features that Windows has had for years • These solid, common foundations makes it easier to extend the Windows Phone platform into the future • It doesn’t mean • Windows 8 and Windows Phone 8 developers work to exactly the same APIs • (though you will see more commonality as new features are introduced to both platforms in the future) What ‘Shared Core’ Does – And Doesn’t - Mean
- 7. Windows Phone 8 Programming APIs Windows Phone 8 supports • Managed app dev using the WP7.1, WP8.0 .NET and WinPRT APIs • Native app dev using WinPRT and Win32 • Games dev using the WP7.1 XNA framework • Games dev using Direct3D or DirectX .NET API for Windows Phone Windows Phone Runtime Win32 & COM Managed Managed & Native Native WP7.1 XAML & C#/VB WP8.0 XAML & C#/VB WP8.0 Games DirectX/Direct 3D & C++ WP7.1 XNA & C#/VB WP8.0 XAML & C#/VB with Direct3D Graphics + C++ + C++
- 8. • The .NET API for Windows Phone is the primary managed API • Includes *all* the types and APIs from Windows Phone OS 7.1 • Contains classes and types from the System and Microsoft.Phone namespaces • There have been new classes added for Windows Phone 8.0, for example • Microsoft.Phone.Wallet • Microsoft.Phone.Tasks.ShareMediaTask • Microsoft.Phone.Tasks.MapsTask • Microsoft.Phone.Storage.ExternalStorage • Microsoft.Phone.Networking.Voip • Many more…! .NET API for Windows Phone .NET API for Windows Phone Windows Phone Runtime Win32 & COM Managed Managed & Native Native

For example, a network share name such as server1folderfile.ext, should always be displayed LTR • In such cases, you can use the Run element to contain the LTR text, and then set the FlowDirection property on the Run element to “LeftToRight” Localization and Globalization RTL and BiDirectional Support
- 57. Consumer Store Coverage: Over 180 countries 120+ new 180+ 123 31
- 58. Developer: Over 180 countries 140+ new 38 Countries Windows Phone 7.x 180+ Countries Windows Phone 8.0
- 59. Languages: 50 languages 26 New Windows Phone 7.5 24 Languages Windows Phone 8 50 Languages
- 60. • Managed Apps are NGEN’d for you (compiled to native) in the Windows Phone Store in Windows Phone 8, so typically start and run faster • When you build your app in Visual Studio, the code is not compiled into a native image, but into a machine-independent Common Intermediate Language (CIL) binary file (formerly known as Microsoft Intermediate Language, or MSIL) • When you submit your app to the Windows Phone Store, you submit the CIL file • On submission, CIL file is converted to optimized Machine Dependent Intermediate Language, or MDIL • When a user downloads your app to a device, it is pre-jitted to a native image Windows Phone 8 Apps Run Faster
- 62. • In general, the Windows Phone app platform enables apps that target Windows Phone OS 7.1 to run without modification or recompilation on Windows Phone 8 • Same APIs may exhibit slightly different behaviour in WP 8.0 compared to WP 7.1 • Feature improvements or behaviour changes Windows Phone OS 7.1 Apps on Windows Phone 8 WP OS 7.1 app WP 8.0 Runtime/ Libraries No recompilation WP OS 7.1 app
- 63. • Instead of breaking WP 7.1 apps running with the WP 8.0 runtime, quirks mode is applied to retain WP 7.1 behaviour • Apps that are upgraded to WP 8.0 and recompiled run on the phone without quirks mode being applied Windows Phone OS 7.1 Apps on Windows Phone 8 WP OS 7.1 app WP 8.0 Runtime/ Libraries No recompilation WP OS 7.1 app +Quirks WP OS 8.0 app WP OS 8.0 app
- 64. • When converting existing WP7.1 code to WP 8.0, be careful that your code does not rely on WP 7.1 behaviour • Two scenarios to consider: • Source code incompatibility – when the code is recompiled for Windows Phone 8, the new WP8 behaviour applies which differs from how the same code behaved when run on WP 7.1 Example: Assembly.GetType property method searches for the specified type in mscorlib.dll as well as in the assembly on which it is called on WP OS 7.1, but on WP8, it searches for the specified type only in the assembly on which it is called • Binary app incompatibility – some behaviors cannot be quirked, so an app that has been written for, and tested on WP OS 7.1 will not run the same on a WP8 device because of a difference in runtime behavior Example: The garbage collector in the WP8 runtime is completely different from that on WP OS 7.1. If your 7.1 code relies on a particular order of object finalization, it may be broken. The dependency on a particular order of finalization should be removed. Converting Code Developed for WP OS 7.1 to WP 8.0
- 65. Source Code Incompatibility Examples Code that Behaves Differently When Compiled for WP8 and Quirks Mode is no longer Applied Item Windows Phone OS 8.0 Windows Phone OS 7.1 IsolatedStorageFile.FileExists(String) method If passed a null, the method throws an ArgumentNullException exception. The method returns false. Mutex class Mutex names cannot include a backslash character A backslash character is allowed in a mutex name and is replaced with another character at run time BeginRead , BeginWrite, EndRead, EndWrite, and subclassed methods Input/output operations are performed asynchronously Input/output operations are performed synchronously Thread.CurrentCulture and Thread.CurrentUICulture properties Changes to the current culture and current UI culture affect only the current thread Changes to the current culture and the current UI culture affect all app threads XmlSerializer class Serialized types must have a default (parameterless) constructor It is not necessary for serialized types to have a default constructor ….many more…. ! See the topic Windows Phone app platform compatibility in the documentation
- 66. Binary App Incompatibility Examples Code that Behaves Differently When run on WP8 , whether it is compiled for WP OS 7.1 or for WP8 Item Windows Phone OS 8.0 runtime behavior change Impact on code that assumes Windows Phone OS 7.1 behavior Background File Transfers The limit on the number of concurrent file transfers has increased from 5 to 25 Code that assumed that the maximum number of transfers cannot exceed 5 will fail Networking Because the Windows Phone 8 Developer Preview client can handle the Vary header and cache responses, a Web service call may complete much faster than in previous versions If you are making a Web service call your code must not rely on the download taking more than a second. When checking the response time it could be less than 1 second. Access to private nested classes Windows Phone OS 7.1 allows a class to access its private nested classes; Windows Phone 8 Developer Preview does not Access to private nested classes is unsupported ….many more…. ! See the topic Windows Phone app platform compatibility in the documentation
- 68. • If you are developing apps for Windows Phone OS 7.1, you must install the Zune software to connect to the Windows PC • Also used to synchronise media • Perform phone updates • Windows Phone 8 devices require only a USB connection Connecting to the Windows Phone
- 69. Developer Phone Registration • Before you can deploy your own programs to the device you need to register it as a developer device • This is done once for a particular phone • Registered developers can register up to three devices • Registered students can register one device
- 70. Deploying to the Phone • Visual Studio lets you select the target device for your program when you run it • The development environment is exactly the same for both platforms • You can debug in exactly the same way for each too
- 71. • Once you have deployed an application the phone device it is stored on the device for later use • You are limited to ten of your own applications on the phone at any one time • You can also send compiled versions of your application to other registered developers for them to use on their developer devices Applications on the Phone
- 72. • Visual Studio provides an exceptional debugging experience • This experience extends to Windows Phone • You can do all the debugging actions in Windows Phone that you can do with a Windows PC application • Breakpoints • Single Stepping • Viewing and modifying variables Visual Studio Debugging
- 73. • Select Device as the deployment target. You cannot test native code generation using the emulator • Deploy and run your app on the device by using Ctrl+F5 (Start without debugging) or Alt+F1 (Start Windows Phone Performance Analysis) to test the app as an optimized native image. • Test the app’s performance and responsiveness To Test Your app as an Optimized Native Image
- 74. • The Windows Phone emulator runs as a Hyper-V virtual machine on your Windows PC • It contains the same software as a “real” phone, but built for the Windows PC platform • The emulator is supplied with the Windows Phone SDK • You can perform location and orientation simulation using the emulator • You can use the Simulation Dashboard in Visual Studio to manage the emulator environment • Lock and unlock the phone • Control the quality and availability of the network connection The Windows Phone Emulator
- 75. • The emulator is not a reliable way of predicting how a program will perform on a real device • The processor in a Windows PC may be more powerful than the one in the phone • The emulator is for functional testing only • If you have any concerns about performance you should ensure you run your program on a real device • There are profiling tools that you can use to inspect the activity of your programs, both in the device and in the emulator Emulator Performance
- 76. • Visual Studio lets you select the target device for a program when it runs • The emulator is started the first time you deploy to it • It will then remain running until you stop it, and maintain its own local storage during that time • Emulators provided for each of the new screen resolutions, plus WVGA 512MB to emulate reduced memory Windows Phone 7.5 devices Deploying to the Emulator
- 77. • You can use the PC mouse to control the emulator • If you have a multi-touch display you can use multiple touchpoints to pinch and zoom on the display • The emulator will emulate the touch keyboard so you can type by clicking on the keys • Use the PgUp/PgDn keys to switch between the emulator software keyboard and using your PC keyboard for text input Emulator Interface
- 78. • Use the command bar at the right side of the emulator to access an extra set of tools • These allow you to rotate the emulator into different orientations • Use this to test how your software responds to orientation changes Emulator Orientation
- 79. Camera Emulation • The camera emulator just “takes” a simple photograph and returns it • You can use this to show your applications are invoking the camera task and receiving the result correctly
- 80. Demo 5: Photo Snap
- 81. • Windows Phone applications can use the emulator to generate location data for them • To do this we open the Additional Tools pane on the emulator Location Emulation 81 Additional Tools
- 82. • This is the Location tab in the Additional Tools • You can click on any location to “move” the emulator to that position • You can also place pushpins to describe a route, and then “replay” that route Additional Tools
- 84. • Showing the Lock Screen in the emulator is a good way of testing what happens when your app is deactivated • Using the Keyboard: • Press F12 on your computer keyboard twice • Using the Simulation Dashboard: • On the Visual Studio Tools menu, open the Simulation Dashboard Lock the Screen in the Emulator
- 85. • Simulation Dashboard also includes Network Simulation • Test your app on the emulator under different simulated network conditions Network Simulation
- 86. • It is very useful to be able to take screenshots of the emulator • These can be used in documentation and also to promote the application in the Marketplace • The emulator Additional Tools pane provides a Screenshot tab Capturing Screenshots
- 87. • New in Windows Phone 8! • Press the power and Windows buttons simultaneously • Easy to share screenshots on social networks Capturing Screenshots on a Real Device
- 88. Summary Windows Phone 8 has very many new features The shared core means that at a low level, components of the OS are the same between Windows 8 and Windows Phone 8 Windows Phone 8 supports XAML+managed, XNA+managed, Direct3D+native app development, and hybrids of those Apps built for Windows Phone OS 7.1 in general run without modification or recompilation on Windows Phone 8
