Microsoft have announced the availability of Silverlight 2, one of the industry’s most comprehensive and powerful solutions for the creation and delivery of applications and media experiences through a Web browser. Silverlight 2 delivers a wide range of new features and tools that enable designers and developers to better collaborate while creating more accessible, more discoverable and more secure user experiences.

New media features in Silverlight 2 include:

The Silverlight team blog has released “Sliverlight 2 RC0”. The blog post says- We’ve released RC0 of Silverlight 2. This is intended as a developer only release - neither the Silverlight 1 nor Silverlight 2 Beta 2 plug-in will auto-update to this release. This is an opportunity to test your Silverlight 2 applications against RC0 to ensure they will be ready for final release. There is also a preview of SP1 for Expression Blend which targets Silverlight 2 RC0.

There is a full list of breaking changes between B2 and RC0, I’ve pulled out the contents list below as a summary:

  • Important! Migrating Older Code to the Newer Release
  • ContentPresenter now derives from FrameworkElement instead of Control
