As you may have already noticed, since the Silverlight 2 Beta 2 was released a week or so ago, and if you have upgraded the Silverlight runtime on your machine, not all applications hosted in Silverlight Streaming work correctly. This is due to several breaking changes in the Silverlight runtime between Beta 1 and Beta 2, which we intend to become compliant with later this week from the Silverlight Streaming service perspective.

This means that you have a few more days to upgrade your Silverlight applications hosted in Silverlight Streaming for them to continue to work with the Silverlight 2 Beta 2 control going forward. It is also important to note that regardless of the Silverlight Streaming work involved in this respect, the Silverlight 2 Beta 1 will expire (and no longer be usable) starting 30 days after the Beta 2 release date and no later than September 1, 2008.
