Silverlight has many strong features, performs well, and to me is the lightweight. The pace of Silverlight development was unusually fast, from version 1.0 in 2007 to version 4.0 in April 2010, and Microsoft bragged about how many developer requests it satisfied with the latest version. Initially just a browser plug-in, Silverlight 3 and 4 took it to the next level, supporting out of browser applications that integrate with the desktop. NET applications on every popular platform, as well as forming a powerful multimedia player. Remember “WPF Everywhere”? Microsoft’s strategy was to create a small cross-platform runtime that would run.
