How will Windows 8

impact on your life?

Windows 8

Windows 8 is pre-Beta

Everything is subject to change

I’m paraphrasing Microsoft, not quoting them.

Situation

Windows 8

More than 1 Billion Windows Devices

94% of new PCs sold in 2011 will use Windows (Gartner)

The State of Windows

Windows 8

450,000,000 copies sold in less than 3 years

More Windows 7 consumer users than XP

1,502 non-security code changes delivered

May 2011: Windows 7 now accounts for one third of worldwide OS market share.

October 2011: Windows 7 overtakes XP with 40% market share.

Drilling in to Windows 7

Windows 7 Adoption

Windows 8

Lies, Damn Lies, and Statistics

Windows 8

A “bold reimagining of Windows” Key Themes:

New design Device Choice Developer Choice Compatibility Performance and Memory Improvements

Let’s take a look!

Windows 8: A Challenger Appears

Windows 8 Demonstration

Windows 8

What did we see? Standard Hardware Full compatibility The new Metro-style Start Screen

Tiles Charms Pinned Apps

Windows 8

This device is a standard Intel i5

Windows 8 base memory footprint is around 60% of Windows 7.

Windows 8 runs fine (better?) on existing hardware.

Devices: Compatibility

Windows 8

Windows 8 can and is running on ARM devices Form factor will be much more like an iPad

New applications will be fully cross-compatible Microsoft have not announced the entire ARM

compatibility story. We have seen ARM versions of Office. I have seen ARM devices with the full desktop enabled.

Devices: ARM

Windows 8 Design

Windows 8

Clean, Light, Open, Fast

Celebrate Typography

Alive in Motion

Content, Not Chrome

Authentically Digital

Metro

Windows 8

The “legacy” desktop mode does not match the Metro start screen.

Touch is not a first-class citizen in legacy mode. Therefore: the legacy desktop mode will be redesigned

prior to final release.

BUT: It still needs to (and will) support Windows apps.

Warning: 100% Pure Speculation

Windows 8 Development

Windows 8

Developers can: develop the same way they have for Windows 7 optionally develop using new APIs develop using the language they prefer

(C#/XAML, C++, HTML5/JS)

Applications built with the new APIs will be installed via an

App Store.

Windows 8 Development: Key Themes

Windows 8 Architecture

Windows 8

OR:

Windows 8

To take advantage of Metro, we need to build new applications (more later)

Very similar process to Windows Phone applications: Submitted via Microsoft

Apps are reviewed and vetted

Apps are searched, rated, and downloaded via the App store.

Apps can be side-loaded and/or distrubuted by enterprises.

Non-Metro apps can be advertised via the App Store

Metro-Style Applications

Windows 8

Applications do not run in the background Apps are suspended and may be terminated under low memory

Apps can be viewed in different layouts Fullscreen, pinned

Background processing tasks are available, and very similar

to Windows Phone 7 E.g. BackgroundTransfer

WinRT Development Considerations

Windows 8

Charms: Items in the Metro interface that interact with Apps

Contracts: Implementation in your app to respond to charms

Charms and Contracts

Windows 8

Register for sharing You can do this easily using visual studio templates

Register and respond to ShareTargetActivated Provide sharing UI

Example: Share Contract

Windows 8

1. Register for Sharing

Windows 8

2. Respond to Event protected override void OnSharingTargetActivated(ShareTargetActivatedEventArgs args) { var shareTargetPage = new HelloWorld.SharingPage1(); shareTargetPage.Activate(args); } public void Activate(ShareTargetActivatedEventArgs args){ // does it contains an image ? var data = args.ShareOperation.Data; bool containsImage = false; data.Contains(StandardDataFormats.Uri, out containsImage); if (!containsImage) return; //Yes: display it ! var bitmapStream = data.GetBitmap(); BitmapImage bitmapImage = new BitmapImage(); bitmapImage.SetSource(bitmapStream); image.Source = bitmapImage; }

Migrating To Windows 8

Windows 8

Windows 7 is your path to Windows 8 Better than 100% device compatibility Smooth upgrade path

Migrating: Users and Enterprises

Windows 8

Do Nothing. OR Think about what your app can do in Metro. Consider how you can extend your app behaviours to other apps

via contracts.
