Dear Collegues Microsoft Silverlight (code-named Windows Presentation Foundation/Everywhere or WPF/E) is a proprietary runtime for browser-based Rich Internet Applications, providing a subset of the animation, vector graphics, and video playback capabilities of Windows Presentation Foundation. The runtime is available for Microsoft Windows and Mac OS X, with Linux support under development via the third-party Moonlight runtime. Silverlight aims to compete with Adobe Flash and the presentation components of Ajax. It also competes with Sun Microsystems' JavaFX, which was launched a few days after Silverlight.[1][2] Click on following link to know the detail. http://www.microsoft.com/silverlight/why-compelling.aspx http://www.microsoft.com/silverlight/default_ns.aspx With Regards, Indu Bhushan Library RRCAT, Indore -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
