- 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

- 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

Editor's Notes
- #14: Managed Managed apps use XAML to define the user interface and Visual Basic or C# as the coding language. Existing Windows Phone apps that were written using these techniques are fully compatible with Windows Phone 8. XAML-based apps have gained new features such as new controls and auto-scaling to high resolution. New managed APIs coming to Windows Phone 8 include a new map control powered by Nokia maps and a wallet API for storing payment methods and enabling NFC-based payments.
- #18: Native Windows Phone 8 SDK supports native development, including significant subset of the Windows 8 SDK, enabling developers to share a significant amount of code between Windows 8 and the phone, particularly for native apps. With the addition of native development support, Windows Phone 8 reduces the need to port and maintain components such as compute engines, graphic libraries, and API sets. In addition to native development, Direct3D is being added to the family of Windows Phone technologies. This means that for the first time, a Direct3D-based PC game can share much of its code base with a phone version, and developers can use state-of-the-art middleware tools and engines that power the industry’s biggest game titles to develop games for Windows Phone. Direct3D app refers to apps that are written entirely in native code, and which use only Direct3D for their UI. This type of app uses a completely different app model than managed apps, and can’t use many of the features of managed apps, such as live Tiles and push notifications.. However, in Windows Phone 8 Developer Preview several new features were added for Direct3D apps to provide software keyboard input support, device theme, and screen resolution detection, and a set of Launchers and Choosers for adding many common phone tasks to your Windows Phone app. Windows Phone 8 SDK supports a subset of the Direct3D library at the 9_3 feature level.
- #19: Direct3D and XAML Direct3D and XAML app development is an attractive choice for developers who want the graphics capabilities of Direct3D but also want to use some of the features only available to managed apps such as Tiles and XAML controls. You can use the DrawingSurface and DrawingSurfaceBackgroundGrid controls to incorporate Direct3D graphics into managed apps to take advantage of managed code features with a very small performance loss.
- #21: XAML/Managed + Native Windows Phone 8 SDK supports the development of solutions where the primary UI is written in XAML using C# or VB, but where a native project is included to perform some processing in native code. This allows the porting of existing components written in C++ for other platforms to Windows Phone and allows managed apps to use them. Developers can enjoy all the productivity and benefits of developing most of the UI of their app using XAML and managed code, but still call out to ported components that have previously been developed in C++ for other platforms. These could be components such as compute engines, graphic libraries, and API sets.
- #23: HTML HTML-based phone apps are not a supported app model in Windows Phone 8 SDK. However, a developer can create an app that uses an embedded browser control to display local HTML content. Also, in Windows Phone 8 SDK, the phone’s browser has been upgraded to Internet Explorer Mobile 10, with a host of new features such as a robust HTML5/CSS3 implementation, Scalable Vector Graphics (SVG), ES5, IndexedDB, gesture events, and the addition of the high-performance scripting engine, creating new, interesting possibilities for Windows Phone 8 SDK HTML developers.
- #24: HTML5 App Project Template A developer can create a managed app with a XAML front end that uses an embedded browser control to display local HTML content, and it’s possible to access phone APIs by using the InvokeScript method and ScriptNotify events.
- #34: There are several things you can do with Tiles: Support multiple sizes, customizable by your customer. Choose from one of three visual templates to help your app stand out. Offer a variety of secondary Tiles. Control which page your customers land on when clicking on your secondary Tiles. The Tile API wraps the OS Tile experience so 3rd party app developers have access to exactly the same tile functionality as the built-in apps.
- #36: You can use Launchers in your Windows Phone 8 Developer Preview app to help a user perform common tasks. The following Launchers are new in Windows Phone 8 Developer Preview. SaveAppointmentTask MapDownloaderTask MapUpdaterTask MapsTask MapsDirectionsTask ShareMediaTask Through the ShareMediaTask class, your app can directly access the share picker, so users can share photos like they do using the built-in photo viewer.
- #39: Speech In Windows Phone 8 SDK, users can interact with your app using their voice.
- #40: Windows Phone 8 SDK introduces the Wallet, which app users can use to do the following: Collect coupons, credit cards, memberships, loyalty cards, and more in one place. Manage the payment instruments that they use in the app and music store. Link items in the Wallet to apps on their phone. Make contactless transactions, using Near-Field Communication (NFC), in some markets. The Wallet gives app developers the ability to provide users with a richer experience by integrating with their Wallet items. Using the functionality provided through the Wallet namespace, you can create, read, write, and delete Wallet items from your app. The Wallet integration is additional functionality that allows you to better reach customers by being able to engage with them on an additional new surface area. In addition, Wallet items enable users to deep link in to your app so that you can provide a more meaningful in-app experience.
- #41: LongListSelector The LongListSelector the Swiss Army Knife of selection. Think of it as ListBox++--, it has everything you expect from ListBox plus a bunch of advanced capabilities and great on-device performance minus the levels of abstraction and generality that tend to slow ListBox down. LongListSelector supports flat lists, grouped lists (with headers!), and also implements the "jump list" header navigation UI that makes the "People" app so efficient!
- #45: With Windows Phone 8 SDK, you can create Voice over IP (VoIP) apps that allow users to make audio and video calls over their data connection. VoIP apps are integrated into the built-in phone experience so that, for example, incoming calls are displayed using the same phone UI as regular cellular calls.
- #47: On two devices that each have a Near-Field Communication (NFC) chip, app users can perform these scenarios simply by tapping their phones, or phone and tablet together
- #48: Windows.Net.Networking The Windows Runtime API, Windows.Networking.Sockets, has been adopted for Windows Phone 8. It has been implemented as a Windows Phone Runtime API, making it easy to use in whatever supported programming language you choose. Although we've enhanced the .NET API, System.Net.Sockets, to support more features such as IPv6 and listener sockets, you should consider using the new API for sockets programming because it is more portable than the .NET API. Windows.Networking.Sockets has been built from the ground up to be clean, secure, and easy-to-use APIs that enforce best practices. Incoming sockets Windows Phone 8 Developer Preview introduces the enhancements to incoming sockets. System.Net.Sockets and Windows.Networking.Sockets both support incoming sockets, which means your app can listen for an incoming network connection, and then bind to that connection. Support for IPv6 Support for the 128-bit addressing system for devices on a network has been added to System.Net.Sockets, and also is supported in Windows.Networking.Sockets. Winsock native API support Winsock native APIs are supported in Windows Phone 8 SDK. One key advantage of using Winsock APIs is that you can reuse the custom networking functionality that you’ve already implemented using Winsock, so it’s easier for you to create your app on the Windows Phone OS 8.0 platform.
- #50: On Windows Phone 8, you can create a custom contact store for your app. When you save contacts to this store, they will appear on the phone’s People hub, integrated with the user’s other contacts. Your contact store can use the standard set of contact properties, such as name and address, but you can also store custom properties for each contact. The contact store APIs also provides a mechanism for you to enumerate changes between your custom contact store on the phone and a contact store you maintain in a cloud service in order to synchronize the two stores. Note: The custom contact store APIs only provide access to the contacts created by your app. If your app needs read-access to the phone’s contact store or calendar, there are different APIs that you should use.
- #51: You can use file and protocol associations in Windows Phone 8 to automatically launch your app when another app launches a particular file type or protocol. For example, a file association allows your app to launch to handle an email attachment. You can also use the association launching API to launch another app based on a specific file type or protocol.
- #52: Using IN-App Purchasing, you can create apps or games that sell virtual products for real money Microsoft servers host the catalog of products that are available for in-app purchasing, including price and descriptive metadata Microsoft also provides a commerce infrastructure, including methods for users to pay in 190 regions around the world All purchase methods that users can use to purchase apps and games are supported for in-app purchasing The app or game must host and deliver any content associated with the in-app product
- #53: For each product that users can purchases through in-app purchasing, a developer enters a description in Windows Phone Dev Center, in addition to prices for each region where users can make the in-app purchase. Using the APIs in Windows Phone 8 Developer Preview, a developer can list, within an app, the products that are available for users to purchase in that app. Developers don’t need to write special code for handling different types of purchase instruments. All purchase methods that users can use to purchase apps and games are supported for in-app purchasing. The app or game must host and deliver any content associated with the in-app product.
- #57: The new project templates create projects that are setup for localization and globalization. They contain all the code elements you need to localize your app.
- #63: 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. However, there are occasional differences in behavior between versions of the Windows Phone Application Platform. Typically, the new behaviour includes a feature improvement or a bug fix.
- #64: Windows Phone 8 introduces feature improvements or behavior changes that may cause incompatibility issues for existing apps. For some features and APIs, rather than introducing a breaking change, the Windows Phone Application Platform provides a quirks mode that preserves the legacy behavior and applies it where appropriate, depending on the version of the Windows Phone the app was originally built and tested for. If the target version is Windows Phone OS 7.1, quirks mode either emulates the same behavior or uses the same code as Windows Phone OS 7.1. In other words, the app runs in Windows Phone 8 as it did when it was tested against the runtime it originally targeted. However, if the source code for an app that targets Windows Phone OS 7.1 is recompiled to target Windows Phone 8, quirks mode is no longer in effect. Because the app now targets Windows Phone 8, it executes the new code in all cases. Quirks mode is not an opt-in or configurable feature—it is applied automatically depending on an app's target platform. There are two scenarios in which a Windows Phone OS 7.1 app may behave differently when it runs on Windows Phone 8 Developer Preview. Source incompatibility and quirks are applied. With source app compatibility issues, there is a runtime quirk provided in Windows Phone 8 Developer Preview that executes the legacy Windows Phone OS 7.1 behavior regardless of the whether the phone is a Windows Phone OS 7.1 or Windows Phone 8 Developer Preview device. When the same app is recompiled for Windows Phone 8 Developer Preview the quirk is no longer applied and the app behaves differently. Binary app incompatibility: When an app that is compiled for Windows Phone OS 7.1 is run on Windows Phone 8 Developer Preview, but does not operate the same because of a difference in runtime behavior.

- #66: The table gives a few examples of quirks mode behavior for common language runtime features and in the .NET Framework for Windows Phone. Windows Phone apps compiled for WP OS 7.1 will run on WP8 with quirks mode applied, so they retain their Wpos 7.1 behaviour. However, if you then upgrade the project to WP8, recompile and re-deploy, the same code will now run without quirks mode applied, so some changes in behaviour may be encountered. Typically, problems will only be encountered if you have written code that implicitly or explicitly assumed WP OS 7.1 behaviour.
- #67: The table shows a few examples of the app compatibility issues between the Windows Phone OS 7.1 and Windows Phone 8 Developer Preview platforms that are not affected by quirks mode. Some of these changes may require modification to your apps so they run the same on Windows Phone OS 7.1 and Windows Phone 8. There are very many more! Read the documentation!
- #69: Connecting to the Windows Phone When you connect a Windows Phone OS 7.1 to a PC for the first time, it will prompt you to download and install the Zune software application onto your PC. This software must be running on the PC to provide the connection to the phone to synchronize media and apply OS updates. Windows Phone 8 devices do not need Zune. Just a USB cable will suffice. When you connect a phone with a USB cable to your PC, the Zune software will launch.
- #70: Developer Phone Registration Before you can debug apps on a real device, you must developer unlock the phone. To do this, you must register on AppHub and pay the $99 per year subscription for a regular developer which then allows you to unlock up to three devices. If you are a student registered in the Drreamspark program, you can register for free and that allows you to unlock a single device. You use the Developer Phone Registration tool which comes with the SDK to register or unregister a phone for development. You have good control over this process, both using the registration tool and also via the App Hub dashboard. Once a phone has been registered in this way it can be used to receive programs from any version of Visual Studio, on any machine. This is much more relaxed than some programs from other vendors.
- #71: Deploying to the Phone You can select the target for the debug session using the dropdown in the Visual Studio toolbar. If you select ‘Device’, the application runs on the phone while attached to the debugger which means you can single step code while programs are running in the phone, and also stop at breakpoints.
- #72: Applications on the Phone When you deploy an application onto a developer-unlocked phone, it is installed alongside any other apps that you install onto the phone through the normal channels, via Marketplace. You can also send the zap file for your app to other developers and they can easily install it onto any developer unlocked phone (or the emulator) by using the Application Deployment tool that comes with the SDK. You are limited to 10 developer apps installed at any time, so you will get an error if you try to install an eleventh. To continue, you must uninstall one of the 10 developer apps by tap and hold on it on the Programs menu on the phone, and then tapping ‘Uninstall’. These restrictions are to prevent too many “sideloaded” programs getting passed around developers.
- #73: Visual Studio debugging This is a big feature. Debugging support in Visual Studio is superb for apps running on either a real device or on the emulator.
- #75: The Windows Phone Emulator The emulator runs a full copy of the Windows Phone OS inside a virtual machine. You can debug your apps on the emulator pretty much the same way as when running on the real phone. The emulator contains most of the complete Windows Phone experience It does have the browser and will provide the phone behaviours for things like placing calls and sending SMS messages It also contains an emulation of the Windows Phone camera, GPS and motion sensors You can also use the emulator to capture screenshots of programs running on the phone
- #76: Emulator Performance Although the emulator runs a proper version of the Windows Phone OS inside a virtual machine, it is running on PC hardware so performance will not be the same as on a real device. They do restrict performance, so it only runs on a single core of a multi-core PC, and XNA games still refresh at 30fps, but certain aspects of an apps performance will not be the same. This tends to become most obvious when you have complex Silverlight animations that may look great on the emulator, but don’t work so well on a real device. The key message here is that you should try to test on one or more real devices to accurately gauge your apps performance on real devices.
- #77: Deploying to the Emulator Simply select the appropriate target in the dropdown on the Visual Studio toolbar.
- #78: Emulator Interface You click with your mouse to simulate touching the screen of the phone. If you have a PC that has a touch sensitive screen, then you can use touch directly onto the emulator screen, just as with a real phone. The emulator is multi-touch aware as well, so you can do pinch and stretch operations and other things that require multiple touch points of contact. Using the PC Keyboard You can press the PgUp (Page Up) key on your PC keyboard to hide the on screen keyboard, and then you can enter text into the phone using your PC keyboard. PgDn (Page Down) reverses this and switches back to the on-screen keyboard. This is not just about making it easier to enter text into apps running on the emulator. Some versions of Windows Phone have hardware keyboards, and that this allows you to test your apps as if they are running on such phones.
- #79: Emulator Orientation You can hover your mouse over the top right of the emulator to show the toolbar. One of the icons on the toolbar allows you to change the orientation of the emulator. When the orientation changes on the emulator or when the user tips over a real phone, the Page OrientationChanged event fires. You can write apps that respond to orientation changes by changing their layout to better suit the re-orientated screen. Most applications support portrait mode. Most games work better in landscape mode. You can choose to have your apps work only in portrait or in landscape, or you can write them to support both and respond to OrientationChanged events to apply a different layout to the UI of your app. Landscape Orientation The button on the emulator allows you to ‘rotate’ the phone either clockwise or anti-clockwise. The supported orientations are portrait, landscape left or landscape right. Note that ‘upside down’ is not supported.
- #80: Camera Emulation The emulator supports an emulated camera. You cannot take real pictures with the emulated camera, even if your laptop has a webcam. When the emulated camera is activated, the viewfinder display shows a simple solid block that moves around the perimeter of the screen. When you ‘take’ the picture it captures the blank screen with the block at that moment. You can use this to test programs that take pictures.
- #81: For demonstration notes please look in the “Demonstration” folder and open the corresponding Word document.
- #82: Location Emulation You can even use the emulator to test apps that use Location services. If you click the lowest button on the emulator toolbar, you can activate the Additional Tools pane. This has tools for emulating the phones current position, for emulating the tilt and rotation of the emulator and for capturing screenshots. These tools are all new in the Mango SDK.
- #83: Additional Tools The Location tab of the Additional Tools pane allows you to set the current ‘position’ of the emulator. By default, the emulators’ position is ‘Unknown’, but as soon as you click on the map on the Location tab, it creates a pushpin at that location, and the phone position is set to that location. If the app you are testing has an active GeoLocater object, a PositionChanged event will fire that your app software can respond to. The default map shown is centered on Microsoft campus in Redmond, WA, but you can move the map to any location in the world. You can type into the search box at the top of the screen to look for a named location anywhere in the world and position the map at that location. When you have created a number of pushpins on the map that describe a route, you can export them to a file. You can import a file of locations and load them onto the map as pushpins. You can replay a route from pushpins on the map and set the time interval between locations. The app you are testing will then get a sequence of PositionChanged events so you can test how your app responds to a sequence of changes of location.
- #84: For demonstration notes please look in the “Demonstration” folder and open the corresponding Word document.
- #87: Capturing Screenshots Screenshots are valuable for putting on web pages or any other form of documentation of your app. Most importantly, you need at least one screenshot when you submit your app for publishing on Marketplace. The screenshot is shown in the Marketplace app on the phone, and on the marketplace entry for your app in Zune and in the web marketplace (http://www.windowsphone.com/marketplace ).
