We believe Silverlight, which is used in more websites everyday, has several beautiful free controls, components and tools that will help you develop websites faster and better.
It is not easy to find the free controls as they are hidden inside the blogs of Silverlight developers or .NET products websites and there are still not so many resources where you can read about Silverlight.
