I’ve started updating my sites that use Silverlight 2 to the RTW bits. So far I’ve got silverlight-tour.com and wildermuth.com updated. SilverlightData.com will have to wait a few days as I have a completely new example that is more complete and dynamically switches between NHibernate and Entity Framework. Look for an announcement on that this weekend.
The only caveat I have for updating your site is if you’re using the Silverlight ASP.NET Control to host your projects. You can copy the SDK to your server if you want but I found that the upgrade to RTW works seemlessly except that I changed the reference to “CopyLocal=True” so I can copy the control to my server instead of expecting it to be installed on the server.
