Silverlight 3 Beta was unveiled at MIX09. It is a preview release which continues Silverlight’s track record of rapid innovation - introducing more than 50 new features, including support for running Silverlight applications out of the browser, dramatic video performance and quality improvements, and features that radically improve developer productivity.
- This is a developer beta release only! This means there is no “go-live” licensing available and the end-user runtime of Silverlight 3 is not available. The tools below are intended for software developers only.
- Once you install the Silverlight 3 Beta Tools for Visual Studio, your development environment will be a Silverlight 3 Beta environment. Visual Studio 2008 SP1 does not support multi-targeting for Silverlight applications so you will be unable to develop Silverlight 2 applications once these tools are installed. We recommend that you install the Silverlight 3 Beta tools on a separate environment if you still need to have the ability to develop Silverlight 2 applications.
- Ensure that you have either Visual Studio 2008 SP1 or Visual Web Developer Express 2008 SP1 installed as it is a prerequisite for the Silverlight 3 Beta Tools for Visual Studio.
