Opera is not listed on the compatibility page even though it is compatible with Silverlight. The new version is available for download for all support platforms (all Windows operating systems from Windows XP SP3 and higher and Intel based Mac OS X 10.5.7 or higher) and web browsers (Internet Explorer 6 and higher, Firefox 3.6 and higher, Safari 4 and higher, Google Chrome 12 and higher). Silverlight 5 now could be the last version of the technology that gets released.
There have been rumors for quite some time now that Microsoft would stop Silverlight development as it was never really able to break Flash's dominance on the world wide web. It is in many regards Microsoft's answer to Adobe's Flash technology. Microsoft has released a new version of Silverlight, a technology for creating interactive web and mobile applications.
