The third update to Redmond's answer to Flash addresses several bugs within the platform. The technology is still not seeing widespread use outside of Microsoft's own sites, but that is not stopping Microsoft from pressing forward with Silverlight. The company is simultaneously working on the second major version as well.
Silverlight 2 will focus on enabling Rich Internet Application development, which includes built in-controls, and will include a built-in version of the .NET framework allowing for more scripting-intensive uses. However for the typical everyday user, there still is the first version of Silverlight. And like the first generation of every other technology, there remain quite a few bugs to be fixed. The new version should show up as 1.0.30401.0 when installed on computers, Microsoft said.
