更新細節：
* New features
- Include Hardware Decode of H.264 media, which provides a significant performance improvement with decoding of unprotected content using the GPU
- Postscript Vector Printing to improve output quality and file size
- Improved graphics stack with 3D support that uses the XNA API on the Windows platform to gain low-level access to the GPU for drawing vertex shaders and low-level 3D primitives.
* In addition, extends the ‘Trusted Application’ model to 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 such as multiple window support, full trust support in browser including COM and file system access, in browser HTML hosting within Silverlight, and P/Invoke support for existing native code to be run directly from Silverlight.

# 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.
# Building next-generation business applications:
* Text improvements make it possible to build rich magazine-style text layouts:
- Multicolumn text and linked text container allow text to flow around other elements.
- Tracking/leading set precisely how far apart each character is for full creative control.
- Text clarity is improved with Pixel Snapping.
- Text layout performance is significantly improved.
- OpenType support has been enhanced.
* 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:
- 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 enhancements:
* Reduced network latency by using a background thread for networking.
# Performance improvements include:
* Reduced network latency by using a background thread for networking.
* XAML parser improvements that speed up startup and runtime performance.
* Support for 64-bit operating systems.
# Graphics improvements:
* Graphics Processing Unit (GPU) accelerated 3-D application programming interface (API) provides rich graphics on the Web for building advanced data visualizations and rich user experience (UI).
* Immediate mode graphics API allows direct rendering to the GPU.
* Hardware acceleration is enabled in windowless mode with Internet Explorer 9.
# Extends features of the ‘Trusted Application’ model to 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.
# Tools improvements include:
* Microsoft Visual Studio profiling support including CPU, memory, thread contention.
* Visual Studio Team Test support.
