Hey Dominique,
I just upgraded to beta 2.2 API and realized that now VS doesn't like the line:
<controls:PrintOverviewLayer />
"It states the value type PrintOverviewLayer cannot be add to a collection or dictionary of type layercollection."
I didn't even think about it when I upgrade, I set my ref back to 2.1 and it went away back to normal.
Is 2.2 not support or do I need to rebuild you dll or something?
Thanks
Dave
