                                          Fact Sheet
                                      April 2011 – MIX11

For plug-in based experiences, we believe Silverlight delivers the richest set of capabilities available to
developers today. Announced last December and shipping later this year, Silverlight 5 makes further
advances in media, application development and user experience, adding over 40 new features.
Available at MIX11, the Silverlight 5 Beta provides developers their first opportunity to start exploring
these new capabilities. More information is available at http://www.microsoft.com/silverlight/future.
The Beta is a major step toward the final release of Silverlight 5 and includes many of the significant
features already announced. The Beta download link and full list of features is available at
http://www.silverlight.net. Visual Studio and Expression Blend tooling support for the Silverlight 5 Beta
is also available.

New Features in Silverlight 5
The following Silverlight 5 features were announced at the Firestarter event in December 2010. The
keynote presentation is available to view at http://www.silverlight.net/news/events/firestarter/.

Premium Media Experiences
Silverlight 5 offers improved media support and rich UI capabilities:
•   Hardware Decode and presentation of H.264 improve performance for lower-power devices to
    render high-definition video using GPU support.
•   “TrickPlay” allows video to be played at different speeds and supports fast-forward and rewind. At
    up to twice the speed, audio pitch correction allows users to watch videos while preserving a normal
    audio pitch.
•   Improved power awareness prevents the screen saver from being shown while watching video and
    allows the computer to sleep when video is not active.
•   Remote-control support allows users to control media playback.
•   Digital rights management advancements allow seamless switching between DRM media sources.
•   Realtime Sound enables low-latency audio playback where split-second playback timing is required.


Application Development and User Experience
Silverlight 5 enhances developer productivity and end user experience for applications:
•   Text improvements make it possible to build high quality, rich text layouts:
    – Multicolumn text and linked text container allow text to flow around other elements and
      between multiple controls independent of placement of the controls.
    – Tracking/leading set more precisely how far apart each character is for extra creative control.
    – Text clarity is improved with Pixel Snapping.
    – OpenType support has been enhanced.
•   Support for Postscript vector printing enables users to create reports and documents, including the
    ability to create a virtual print view different from what is shown on the screen.
•   Applications can now work the way users expect with added support for double-click and Combobox
    type ahead.
•   Model View ViewModel (MVVM) and Databinding enhancements allow more work to be done more
    easily via XAML:
    – XAML Debugging support now allows breakpoints to be set on a binding, so you can step
      through binding failures.
    – Implicit DataTemplates allow templates to be created across an application to support a
      particular type by default.
    – Ancestor RelativeSource allows, for example, a DataTemplate to bind to a property on the
      control that contains it.
    – Binding in style setters allows bindings to be used within styles to reference other properties.
    – The DataContextChanged event is being introduced.
    – Markup extensions allow code to be run at XAML parse time for both properties and event
      handlers, enabling cutting-edge MVVM support.
–   Networking and Windows Communication Foundation-based enhancements:
    –   Reduced network latency by using a background thread for networking.
    –   WS-Trust support: message security — encrypted at the Windows Communication Foundation
        level; Security Assertion Markup Language authentication token.
–   Silverlight 5 performance improvements include:
    – XAML parser improvements that speed up startup and runtime performance.
    – Support for 64-bit operating systems.
    – Multicore JIT (Just In Time) Compiler optimization.
    –   Text layout performance..
•   Graphics improvements
    – Silverlight 5 now has a built-in XNA 3D graphics API to enables you to build rich, GPU accelerated
      visualizations and rich user experiences. This includes a new 3D drawing surface control as well
      as immediate mode GPU access, shaders and effects.
    – Hardware acceleration is enabled in windowless mode with Internet Explorer 9.
    – The graphics stack has been rearchitected bringing improvements from Windows Phone 7 such
      as independent animations.
•   The Pivot viewer control enables a visual way to rapidly sort through large collections of graphical
    data, for example a catalog of movies represented by images of dvd covers, using intuitive
    transitions to show the effects of filters on the result set.
•   Silverlight 5 enables trusted applications to run in the browser for the first time. These features,
    when enabled via a group policy registry key and an application certificate, mean users won’t need
    to leave the browser to perform complex tasks:
    – Host HTML content as a Web browser control within the Silverlight application. HTML pages,
      such as help content or e-mail, can be integrated within the application.
    – Read and write files to the user’s My Documents folder, making it easier to find media files or
      create local copies of reports.
    – Launch Microsoft Office and other desktop programs. Users can open Microsoft Outlook and
      create an e-mail message, or send a report to Word utilizing the power of Office.
    – Access devices and other system capabilities by calling into application COM components. Users
      can access a USB security card reader or a bar-code scanner.
    – Enjoy full keyboard support in full screen, which enables richer kiosk and media viewing
      applications.
    – Call existing unmanaged code directly from within Silverlight with PInvoke.
•   Existing trusted application capabilities are further extended:
    – Existing unmanaged code can be called directly from within Silverlight with PInvoke.
    – Child Window support allows multiple independent windows to be launched from the
      application.
    – File System access is extended beyond MyDocuments to the entire file system.
•   Tools improvements include:
    – Microsoft Visual Studio profiling support including CPU, memory, thread contention.
    – Visual Studio Team Test support.

As always, the final product and features included will be dependent on customer and parter feedback
and testing that comes from the beta process.
