Microsoft Silverlight does not come with all versions of Windows; however, the browser plug-in is available for free downloading to all supported platforms from Microsoft's website. The download is offered free of charge.
Microsoft Silverlight is supported by all major operating systems such as Mac and Linux. Silverlight is currently compatible with most browsers, including Internet Explorer, Safari, Firefox and Google Chrome. Silverlight 5 is the most recent and final version of Microsoft Silverlight. It was released on May 8, 2012.
Google Chrome will cease to support all versions of Microsoft Silverlight in April 2015. This will be done so that Google Chrome can begin the transition to HTML5 technology. In a post republished to geocortex.com, Google cites the multiple benefits of HTML5 technology — no need for plug-ins and cross platform support — as the reason behind the switch. While experienced users may still be able to run Microsoft Silverlight in April, less experienced users will be unable to subvert the system. Finally, In September of 2015, even experienced users will be forced to forfeit their Silverlight usage, as Google Chrome will entirely lose the ability to support the plug-in. According to Google, the transition from Microsoft Silverlight to HTML5 technology has been in the works since 2011.
