title: mvvm-light and silverlight 4 compatibility
body: <p>I've downloaded the mvvm light toolkit source 4157, and try to use the EventToCommand.SL sample. It works well in Visual Studio 2010, if I use the silverlight 3 framework.</p>
  
  <p>But if I select the silverlight 4 version (EventToCommand.SL project properties), nothing appears : the ViewModel method associated with the Command property is never executed. The setter of the Command property of the EventToCommmand class is not reached !</p>
  
  <p>Is there something that I missed ? Or is there a workaround ?</p>
  
  <p>Thanks</p>
