Silverlight

Silverlight is a free plug-in powered by the .NET framework that is compatible across multiple browsers, devices and operating systems to bring a new level of interactivity wherever the Web works. With support for advanced data integration, multithreading, HD video using IIS Smooth Streaming, and built in content protection, Silverlight enables online and offline applications for a broad range of business and consumer scenarios.

Microsoft Silverlight

Microsoft Silverlight is a web application framework that integrates multimedia, computer graphics, animation and interactivity into a single runtime environment. Initially released as a video streaming plug-in, later versions brought additional interactivity features and support for CLI languages and development tools. The current version 4 was released in April 2010. Features of Silverlight are similar to those in Adobe Flash.
It is compatible with multiple web browsers used on Microsoft Windows and Mac OS X operating systems. Mobile devices, starting with Windows Phone 7 and Symbian (Series 60) phones, are likely to become supported in 2010. A free software implementation named Moonlight, developed by Novell in cooperation with Microsoft, is available to bring most Silverlight functionality to Linux, FreeBSD and other open source platforms.
