Only 4 months have passed since 10 July 2009 - when Silverlight 3.0 has been released - and the last 18th November at the PDC the first beta of Silverlight 4.0 has been launched to the world. In this short time great work has been accomplished by the Silverlight team, adding some impressive new features, tuning some others and fixing a lot of bugs.
During this short time the development has been driven from people which have sent more then 12000 votes on a special site created to collect the preferences (http://silverlight.uservoice.com/).
