Microsoft recently released Silverlight (1.0 Beta), previously known as WPF/E (Windows Presentation Foundation/Everywhere).
Silverlight is a proprietary technology for animation, vector graphics and video playback. Similar to Adobe Flash (formerly Macromedia Flash), the Silverlight runtime is available as a plugin for many browsers and platforms including our beloved Apple Safari on Mac OS X (installation link).
Silverlight is a cross-browser, cross-platform plug-in for delivering the next generation of .NET-based media experiences and rich interactive applications (RIAs) for the Web. Silverlight offers a flexible programming model that supports AJAX, Visual Basic .NET, C#, Python, and Ruby and integrates with existing Web applications. Silverlight media capabilities include fast, cost-effective delivery of high-quality audio and video to all major browsers including Mozilla Firefox, Apple Safari, and Windows Internet Explorer running on Mac OS or Microsoft Windows.
