SimpleViewer-SL now works on Beta 2 as well. I updated the inline samples in the previous posts so folks with Beta 2 should be able to view all the sample galleries that I created using SimpleViewer-SL.
If you recollect from my earlier post, I did not use the ScrollViewer control since I wanted to keep the .xap package as small as possible. This is no longer the case since ScrollViewer is now part of the Silverlight framework itself. I still haven't updated the code to take advantage of this but might do so at a later date.
