I have successfully gotten all the samples working with Silverlight 3.0/4.0 in Visual Studio 2010. It's mostly a matter of finding out where everything has moved and adding the right references.
What I really want to do is create Sharepoint 2010 web parts that work similarly to the PerformancePoint ones and can link up to other web parts and/or data sources to drive the appearance and data values of the gauges and other controls. So far
it looks like the SharePoint Silverlight support doesn't really allow this, unless I'm missing something (not unlikely).
In any case has anyone tried anything similar? All ideas and suggestions will be appreciated.
