title: Does an AddHandler require parameters?
body: <p>I'm trying to add a handler, but as soon as I'm targetting a method that has parameters, the handler fails. This is the simple code:</p>
  
  <pre><code>AddHandler App.Current.RootVisual.MouseLeftButtonUp, RootVisual_MouseLeftButtonUp
  
  Private Sub RootVisual_MouseLeftButtonUp(ByVal sender As Object, ByVal e As MouseButtonEventArgs)
  
  End Sub
  </code></pre>
  
  <p>This error won't let me build. When looking at the examples, I'm doing it right. This is the error I get:</p>
  
  <blockquote>
    <p>Error 3   Argument not specified for parameter 'e' of 'Private Sub
    RootVisual_MouseLeftButtonUp(sender As Object, e As
    System.Windows.Input.MouseButtonEventArgs)'.  C:\TFS\ProjectCollection\ItemManagementTool\ItemManagementTool.ClientApplication\Views\MainMenu.xaml.vb 82  70  ItemManagementTool.ClientApplication</p>
  </blockquote>
  
  <p>I get a similar error for the "sender" parameter.
  Any ideas?</p>
