Windows 8 Platforms and Tools Metro Style Applications Desktop Applications XAML Javascript, CSS HTML C, C++ / C#, VB Normal Desktop Applications Communication Graphics & Devices & and Data Media Printing Win 32 Native Apps Application Model Windows Kernel Services

Why Metro Application Metro Style application are full screen, device ready, touch interactive applications. They are more alive & truly designed for multi tasking Supports fluid layout, so content flows freely and adapts to available space. Application Store

Conventions and Rules Everything should be in background. UI threads must be responsive. Layout needs to support Snapping. (FullScreen, Fillled, Snapped) UI elements should follow standardization. (Application Bar, Charms etc.) Packaging and Deployment is recommended to be done via App Store

FEATURES

Live Tiles Tiles are like Icons. They provide facility to update tile content even when the application is not running Tiles are bigger than Icon and helps you easily Tap using Thumb. Size of Tile can be made Small or Big based on content you want.

Chirms Each application is provided with Chirms. Chirms are special tools that allows an application to interact with the environment. Chirms allows you to navigate to different settings (Search, Share, Settings etc.)• Windows+F – Opens File Search• Windows+C – Opens Charms Bar• Windows+I – Opens Settings• Windows+Q – Opens App Search pane• Windows+W – Opens Settings Search app• Windows+Z – Opens App Bar

Application Bar Provides standard set of Icons in form of a Application Toolbar. ApplicationBar generally applied on top or bottom of the application. Shortcut for Application Bar is : Win + Z Application Bar provides standard access to activities required for an application

Layout & Convensions

WORKING WITH APPLICATIONMANIFEST

Capabilities Windows 8 runs in constraint environment Capabilities define what the application is capable of. Some capabilities are treated as sensitive and hence depends on User preference. User has flexibility to switch on / off.

Declarations General declarations on which the application can participate. Example : File Type association, Global search, Background Tasks etc.

Capabilities

Application Life Cycle Windows Metro application does not need to be stopped by the User. Application must Detect Suspension, Termination or Resumption. Application automatically gets to suspended mode after 5 seconds. Application gets terminated when it is not used for a long time

Debugging in VS Visual Studio debugger never suspend an application. Visual Studio has special menu which lets you Debug Suspension and Resumption of the application.

Application Life CycleManageent

Packaging And deployment Application Store Packaged using digital signature Zip content with XAML in plain text. Debug symbol files. VS generates additional files for local deployment

Package includes Compiled Code & Custom dlls (if any) XAML (not compiled) Resources Manifest Digital signature
