Silverlight 3 Beta

Today at the MIX ‘09 conference, we rolled out the beta for Silverlight 3, the next iteration of our rich internet application platform. Version 3 adds a lot of new features including:

  • Out of Browser Capabilities. Silverlight 3 applications aren’t just confined to the browser. Users can install and run them from their desktops – either Windows or Mac OS – and without having to download any additional runtimes or plugins. Better still, these desktop Sliverlight apps can detect whether the machine is connected to the internet and can also auto-update.
  • Richer Graphics. There’s support for perspective 3-D graphics, pixel shader effects, a bitmap API, bitmap caching of vectors, text and controls, support for themed applications, new animation effects, enhanced control skinning and improved text rendering and font support.
  • HD Video and Audio. Support for H.264/AAC, 720p+ live and on-demand streaming, true HD playback in fullscreen mode and support for third-party codecs.
  • Better application features, including:
    • New GUI controls, including their source code
    • Support for “deep linking”: it’s now possible to bookmark a page contained within a Silverlight app
    • SEO tools: The content of your Silverlight apps can be mirrored into HTML so your app can be indexed by search engines
    • Enhanced data support
    • Improved performance

Expression Blend 3 Preview

Microsoft Expression Blend Also available is the preview version of Expression Blend 3, the “designer/developer workflow tool” for building interfaces for Silverlight and WPF projects. As with Silverlight 3, Expression Blend 3 adds a lot of new features including:

  • Sketchflow: a tool that lets you tool for quickly creating application prototypes, complete with interactivity.
  • Behaviors, which let you add interactivity to an application without having to write code
  • Photoshop and Illustrator file import
  • Improved design and development experience

An Important Note for People Currently Building Silverlight 2 Apps

Do not install Silverlight 3 development tools on a machine that you’re using to build Silverlight 2 apps! Visual Studio doesn’t support targeting multiple versions of Silverlight; if you install Silverlight 3 tools, you won’t be able to build Silverlight 2 apps anymore!

My recommendation is:

  • If you’re going to be working on Silverlight 2 projects, install Silverlight 3 tools on a machine that you’re not using for Silverlight 2 production.
  • If you’re like me and not doing any work on Silverlight apps at the moment and want to get started, go ahead and grab the beta.
