With the substantial number of new features and API added to the Silverlight 1.0 Beta release since the February CTP release, I decided to compile a list of the new API. I've grouped them into feature areas.

  • New Inking Support
  • Enhanced Error Handling Support
  • New Animation, Graphics, and Media Features
  • Redesigned Silverlight Control Model
  • New Text and Font Support
  • Other New Support

See Silverlight 1.0 Beta Enhancements and Converting a WPF/E Application to a Silverlight Scripting Application for other info on changes to the Silverlight programming model.
