My friend Laurent Duveau will be teaching Silverlight 4 in January (17 to 20) in Montréal and in French.
I will be sitting in that room because I want to learn it quickly.
There are still some available spots. Visit http://weblogs.asp.net/lduveau/archive/2011/01/02/silverlight-training-montreal-in-january-2011.aspx for more details.
