1.) Is Silverlight the official name for “WPF/E”?
Yes. Silverlight was formerly code-named “WPF/E.”
2.) Does silverlight web application work with all browsers ?
Yes, A web application developed by silverlight technology can work with any browser
3.)What are the main features and benefits of Silverlight?
-Compelling cross-platform user experiences.
-Flexible Programming Model with Collaboration Tools.
-High-quality media, low-cost delivery
-Connected to data, servers, and services
4.) How can I build experiences and applications with Silverlight?
Silverlight development tools include role-specific productivity tools for both designers and developers:
* Expression Studio empowers designers to create interactive UI and media-rich experiences, prepare media for encoding and distribution, and create W3C standards-compliant sites using modern XHTML, XML, XSLT, CSS, and ASP.NET. Expression Design includes support for exporting XAML for Silverlight. At MIX 07, Microsoft released Expression Blend 2 May Preview and Expression Media Encoder Preview to enable designers to build media experiences and RIAs.
* Visual Studio empowers developers to develop client and server code using full IntelliSense, powerful debugging, rich language support, and more.
By using Expression Studio and Visual Studio, designers and developers can collaborate more effectively using the skills they have today. Additionally, Silverlight supports a consistent subset of XAML (eXtensible Application Markup Language) for declarative programming, the same format found in .NET 3.0. Because XAML is toolable, there is always the potential for third-parties to provide additional XAML-based Silverlight tools in the future.
5.) How does Silverlight make the Microsoft development system better?
Silverlight is a cross-browser, cross-platform plug-in for delivering the next generation of media experiences and rich interactive applications (RIAs) for the Web. Examples include:
* For ASP.NET-based Web applications, Silverlight provides a rich UI front-end that, with a consistent programming model, adds support for richer interactivity, media, and audio.
* For Microsoft SharePoint–based content, Silverlight offers the ability to create rich Web parts.
* For Windows Live services, Silverlight offers the ability to consume services and APIs more effectively.
6.) What audio or video formats are supported in Silverlight?
Silverlight supports Windows Media Audio and Video (WMA, WMV7–9) and VC-1, as well as MP3 audio. Additional formats may be available by the final release based on customer feedback.
7.) Will Silverlight support all the codecs Windows Media Player supports?
Since Silverlight is a lightweight cross-platform technology, it only carries the most common codecs that are needed for Web playback. However, we are gathering information from customers about the needed codecs and can update Silverlight when necessary.
8.) Will Silverlight support digital rights management?
For content providers, Silverlight will support digital rights management (DRM) built on the recently announced Microsoft PlayReady content access technology on Windows-based computers and Macintosh computers.
Microsoft Silverlight is a cross-browser, cross-platform, and cross-device plug-in for delivering the next generation of .NET based media experiences and rich interactive applications for the Web. By using Silverlight’s support for .NET, High Definition video, cost-effective advanced streaming, unparalleled high-resolution interactivity with Deep Zoom technology, and controls, businesses can reach out to new markets across the Web, desktop, and devices(Fig. source : MS Site).
Silverlight provides a retained mode graphics system similar to WPF and integrates multimedia, graphics, animations and interactivity into a single runtime environment. In Silverlight applications, user interfaces are declared in XAML and programmed using a subset of the .Net framework. XAML can be used for making up the vector graphics and animations.
1.) Is Silverlight free?
Yes, Microsoft has made the Silverlight browser plug-in freely available for all supported platforms and browsers.
2.)What is the long-term goal or vision for Silverlight?
Microsoft Silverlight is a cross-browser, cross-platform, and cross-device plug-in for delivering the next generation of .NET based media experiences and rich interactive applications for the Web. Silverlight offers a flexible programming model that supports AJAX, VB, C#, IronPython, and IronRuby, and integrates with existing Web applications. By using Expression Studio and Visual Studio, designers and developers can collaborate more effectively using the skills they have today to light up the Web of tomorrow. By leveraging Silverlight’s support for .NET, High Definition video, cost-effective advanced streaming, unparalleled high-resolution interactivity with Deep Zoom technology, and controls, businesses can reach out to new markets across the Web, desktop, and devices.
3.) When would a customer use Silverlight instead of ASP.NET AJAX?
Silverlight integrates with existing Web applications, including ASP.NET AJAX applications. Consequently, ASP.NET AJAX and Silverlight are designed to be complementary technologies. In the broader sense, Silverlight can talk to any AJAX application, both client-side and server-side. ASP.NET AJAX can additionally be used to control Silverlight-based visualization of data or delivery of rich experiences. Examples might include mapping applications or video playback with rich presentation.
4.) Will Silverlight support live streaming events as well as downloading media?
Yes. Silverlight together with Windows Media Services enable live streaming experiences.
5.) When would a customer use Silverlight versus Windows Presentation Foundation? Is Silverlight for a certain type of application?
For ASP.NET-based Web applications, Silverlight provides a rich UI front-end that, with a consistent programming model, adds support for richer interactivity, media, and audio.
For Microsoft SharePoint–based content, Silverlight offers the ability to create rich Web parts. For Windows Live services, Silverlight offers the ability to consume services and APIs more effectively.
6.) Will Silverlight work with my new or existing Windows Media services platform for streaming?
Silverlight takes advantage of Windows Server features for streaming.
