One of the design goals of the Silverlight technology is to fill the gap between Windows applications
and web applications in terms of creating Graphical User Interfaces (GUI). So far, web developers
were not able to make clients happy in terms of UI, but now web developers will be able to fullfill this
with the help of the Silverlight technology.

Silverlight supports multiple browsers called cross-browser technology,which includes
Internet Explorer,Firefox and Safari,Opera etc…

Advantages:-

CLR supports, like C#, VB.NET, dynamic languages (IronPython, IronRuby).
Better development tools – Visual Studio 2010, Expression Blend.
Integration with Enterprise based technologies like WPF, LINQ etc…
