The most straight-forward way i've found to do this, especially for listbox (or listview) that is bound to a data source is to hook it up with the collection change event. You can do this very easily at DataContextChanged event of the listbox:

    //in xaml 
    private void LogView_DataContextChanged(object sender, DependencyPropertyChangedEventArgs e)
    {
      var src = LogView.Items.SourceCollection as INotifyCollectionChanged;
      src.CollectionChanged += (obj, args) => { LogView.Items.MoveCurrentToLast(); LogView.ScrollIntoView(LogView.Items.CurrentItem); };
    }

This is actually just a combination of all the other answers i've found. I feel that this is such a trivial feature that we should not need to spend so much time (and lines of code) doing.

If only there was an Autoscroll = true property. Sigh.
