Yesterday I gave a conference on LinQ to Objects at the .NET Montreal Community. The format was not your typical conference, it was a coding dojo!
Everything went well and I think many people enjoyed to event. I'm posting a link to the solution that contains all the exercices the group did with the the answers included. Unfortunatly, it's in french :) If someone would like to have the exercices in english, about 20 of them, please post a reply and I'll put the english version here ASAP...
