Windows 8.1 API Improvement

In Windows 8 we have Two UI’s Two Development Worlds

Assynchronous API

• A new scheduler API lets you set the priority of tasks and manage jobs.• The Scheduler is a new object/namespace that

consolidates all work queues into a single, universal queue. This new queue has a priority-based scheduling policy that supports fast and fluid apps and a more unified developer experience

Assynchronous API

// Schedule some work. var job1 = S.schedule(function () { window.output("Running job1");}, S.Priority.normal);window.output("Scheduled job1");

// Schedule more work.var job2 = S.schedule(function () { window.output("Running job2");}, S.Priority.normal);window.output("Scheduled job2");

Network Improvements• “A new HTTP API for apps that target HTTP or REST-based services. This API offers more

capabilities and better performance to support today’s connected apps. The HTTP capabilities are deeply integrated into Windows, and the API is flexible enough to support basic, site-specific, and advanced HTTP development scenarios.”

• “Single sign-on, credentials are effectively shared from IE to the Web Authentication Broker, and to other services the user interacts with”.

• “HTTP prefetching: Nearly every app is connected to a service. With Windows 8.1 Preview, apps can take advantage of prefetching app content via HTTP before it’s actually needed—that way the content is ready immediately when the user wants it. Using this API, a background task can download content using a list of URI resources that should be prefetched”

And what more?

• Windows Store apps using C++ can now natively render PDF content directly to a DirectX drawing surface. This enables fast and fluid presentation of PDF-based content within a Windows Store app

• Windows Store apps now support the same text-to-speech technology as other Windows apps, using easily invoked Windows Runtime APIs.

Devices

• USB • Human interface devices (HID) • Bluetooth • 3D printing
