We are currently getting ready to post an update to our library.
This update was built against the lastest version of Silverlight, the Beta 2.0 Microsoft just published at Mix last week. The update will be available for download later on this week (Friday at the latest).
The main goal for this update was compatibility with our public Alpha bits and of course with the SL 2.0 beta. We are not yet taking advantage of the new features in SL 2.0. That will be the goal of the next version of the library, which we will announce soon after this update is posted.
