I meant to blog this last week when I noticed the announcement during the Silverlight DevCamp in DC that ComponentOne had released an Alpha Preview of their Silverlight 1.1 control framework.
I've been following along with great anticipation as they seem to have one of the most complete control solutions. We're all still anxiously awaiting the official Silverlight control story is going to be, C1 is certainly showing how great the potential is.
You can learn more and signup for the alpha release here:
