Microsoft has released RC0 for Silverlight 2 to allow developers to have time get used to the new changes before releasing to end users. Scott Guthrie posted a good overview of the updates that were included in the RC0 release. You can read a complete list of the breaking change from here.

 Here are some of the new changes in this release:

  • PasswordBox control added
  • ProgressBar control added
  • ComboBox control added
  • New control templates (they’re much cleaner than the previous ones IMHO)
  • API changes here and there and elimination of some assemblies such as System.Wondows.Controls.Extended
