It scales video quality to everything from mobile devices to desktop browsers to 720p HDTV video modes.</LI> <LI>It includes compelling graphics that users can manipulate directly in the browser. </LI> <LI>WPF and XAML. Silverlight includes a subset of the Windows Presentation Foundation (WPF) technology, which greatly extends the elements in the browser for creating UI, extending browser-based UI beyond what is available with HTML alone. Extensible Application Markup Language (XAML) provides a declarative markup syntax for creating elements. </LI> <LI>Extensions to JavaScript. Silverlight provides extensions to the universal browser scripting language that provide control over the browser UI. </LI> <LI>Integration with existing applications. Silverlight integrates seamlessly with your existing JavaScript and ASP.NET AJAX code to complement functionality you have already created.&nbsp; </LI> <LI>Access to the .NET Framework programming model and to associated tools. You can create Silverlight-based applications using dynamic languages such as IronPython as well as languages such as C# and Visual Basic. You can use development tools such as Visual Studio to create Silverlight-based applications. </LI> <LI>Networking support. Silverlight includes support for HTTP over TCP. You can connect to WCF, SOAP, or ASP.NET AJAX services and receive XML, JSON, or RSS data. </LI> <LI>LINQ. Silverlight includes language-integrated query (LINQ), which enables you to program data access using intuitive native syntax and strongly typed objects in .NET Framework languages. </LI></UL> <P>Got more time?
