For Metro applications, a screen resolution of1024x768 or higher is required. 4. Development & Platforms Windows 8 represents a reimagining of Windows from thechipset to the experience. Since this is a week focused ondevelopers, we also detailed the bold underpinnings of the re-imagination of the Windows platform, tools, and APIs We willshow the brand new tools that allow you to code Metro styleapplications in HTML5/JavaScript, C/C++, and/or C#/XAML. Metro is an internal code name for a typography-based designlanguage created by Microsoft, originally for use in WindowsPhone 7. Early uses of the Metro principles, such as thetypography, began as early as Microsoft Windows 8. "Metro" isbased on the design principles of classic Swiss graphic design. 5.

Who To Use & What To Use Web developers can use their HTML5, CSS3, and JavaScriptskills to build native applications for Windows. NET Developers can use XAML, C#, and Visual Basic to buildbeautiful Metro style apps. Game developers can use the power of DirectX 11.1 to buildamazing, immersive gaming experiences. Driver developers can use the new, integrated MicrosoftVisual Studio development environment to increaseproductivity. 7. Features Windows Live ID IntegrationWith Windows 8 you could now move to clouds.With this new feature you can integrate your localaccount with Windows Live ID account andsynchronize your data online. Undoubtedly its one ofthe remarkable features as it ensures that whether yoursystem crashes or you lose your device, all your datawill be safe and secure. 8.

Built-in AntivirusMoreover, Windows 8 has an antivirus presentinside the kernel of the operating system.This means that your system wont boot if acorrupt USB device is plugged in.It sounds impressive though I dont know whetherit would pass the test of time. and virusesI genuinely believe that Microsoft is finally readyto launch an OS which will take the world by storm! 20. Along with the new UI interface, there have been manyimprovements in Windows 8 for scaling to differentscreen resolutions, screen sizes and pixel densities. Even though this may seem minor, you will be able touse Windows 8 on everything from a small Windowsphone to a giant 30 inch screen with a 2560 1600resolutionScaling for Different Screen Sizes 21. Windows Store and Apps The Metro interface looks and feels like a Smartphoneor tablet OS, and following that theme is the inclusionof the Windows Store in Windows 8. This online shop front is stuffed full of Windows apps -each designed to run on x86 Windows PCs, laptops andtablets, as well as ARM tablets and smart phones. Windows 8 apps follow the same design principle asMetro - being constructed of cascading live tiles ofinformation, in primary colors. 22. Security, Cloud, Task manager There are a couple of other relatively minor, butsignificant changes in Windows 8 that may make itworth an upgrade for Windows 7 users. Windows 8 has a cloud focus to it which might be atempting feature. Microsoft stores all your settings and customizations inthe cloud so whenever you log on to a Windows 8machine you will have it looking and working yourway. 23. Speed Thats about it in terms of significant featurechanges, but Microsoft would have us believe thatWindows 8 is much faster than Windows 7 - it certainlyworks on the same hardware, which removes onebarrier to upgrade. 24. Introduction to Windows AppDevelopment Before you start... Choose C# and Visual Basic Part 1: Create a "Hello, world" app Step 1: Create a new project in Visual Studio Step 2: Start the app Step 3: Modify your start page Step 4: Create an event handler Part 5: Style the start page 25. Step 1: Create a new project inVisual Studio Launch Visual Studio Express 2012 for Windows 8. The Visual Studio Express 2012 for Windows 8 start screenappears. (Going forward, well refer to Visual Studio Express 2012for Windows 8 as just "Visual Studio".) Select File>New Project. The New Project dialog appears. The left pane of the dialoglets you select the type of templates to display. In the left pane, expand Installed > Templates, then expandVisual Basic or Visual C# and pick the Windows Storetemplate type. The dialogs center pane displays a list ofproject templates for Windows Store apps. 26. In the Name text box, enter "HelloWorld".Click OK to create the project 27. Although the Blank App is a minimaltemplate, it still contains a lot of files:A manifest file (package.appxmanifest) thatdescribes your app (itsname, description, tile, start page, and so on)and lists the files that your app contains.A set of large and small logo images (logo.pngand smalllogo.png)to display in the start screen.XAML and code files for the app (App.xamland App.xaml.cs/.vb) .A start page (MainPage.xaml) and anaccompanying code file (MainPage.xaml.cs/.vb)that run when your app starts. 28. Step 2: Start the app At this point, you created a very simple app. The splash screen disappears, and then yourapp appears. It contains a black screen and thetitle "My Application". 29. App.xaml 30. 31. Conclusion These ten features only touch the surface of what isavailable to developers for building applications thattarget the new Windows 8 Metro platform. Microsofthas created a platform that allows you to developusing the language and design tool of yourchoice, implements complex interfaces in a simpleway, and creates unprecedented interoperabilitybetween different applications
