Microsoft Silverlight rivals Flash, AJAX
Redmond's new rich Internet application boasts strong development tools, a small browser footprint, and cross-platform support
The online Silverlight QuickStarts should give most developers enough of a feel for the product to get started with simple projects. Additional reference information on MSDN and in the SDKs helps a bit, but a number of Microsoft Technical Evangelists and bloggers have created videos to make the process even clearer. Some of the videos go further afield, covering useful topics you never expected to hear about from Microsoft, such as integrating Silverlight with PHP and Java, and using SVG (Scalable Vector Graphics) assets in Expression Design.
Silverlight 1.1 supports a larger subset of the .Net Framework than Silverlight 1.0, enabling the development of some fairly serious applications, not to mention some fairly cool games. In Silverlight 1.1 you can do networking and communication, process XML, use isolated local storage, upload files, and use compiled dynamic languages such as IronPython.
But Silverlight 1.1 is still a work in progress. In the meantime, should you jump for Silverlight 1.0? If I had a site that could benefit from streaming media and simple animations, and was intended for viewing on Windows and Mac computers, I wouldn't hesitate to use Silverlight 1.0, especially if I had a development staff familiar with Visual Studio and XAML. On the other hand, I wouldn't spend the time and money needed to convert an existing Flash or Flex site to Silverlight 1.0. If performance were an issue, I'd revisit the question when Flex 3 and Silverlight 1.1 are released.
If I had a site that displayed embedded videos from YouTube, I'd have to decide if the additional interactive features I could get from Silverlight made up for the additional bandwidth cost. If my videos fit within the free 4GB hosting restriction of Silverlight Streaming by Windows Live, bandwidth wouldn't be an issue, and I'd strongly consider moving my content.
