Hello Laurent,
Right, but for an existing project it's a bit more involved and frankly I don't see what MVVM Light could do about it. It's just a bit of work that requires a human. You also have to copy over all the files auto-created by the new MVVM Light template in the Common, Design, & Model sub-directories to the existing MVVM Light project and adjust the namespace lines. In addition, you have to copy over the needed changes from the new MainViewModel file to the existing one. That's just the way it is sometimes. It only takes about 30 to 45 minutes and it's definitely worth it.
That's a good article about EventToCommand. I created an EventBehaviorTrigger yesterday with Blend to trigger a ViewModel Command that I need to execute when the pageRoot Loaded event fires. Saved me from doing some really ugly, awkward code to make that happen. :)
