title: Why do certain properties need to be surrounded in parenthesis..ex: Storyboard.TargetProperty="(Background).(SolidColorBrush.Color)
body: <p>The title pretty much sums it up.  I was stuck on an issue with a ColorAnimation not working properly.  I eventually figured out that the TargetProperty had to be surrounded in parenthesis...although I don't fully understand why?</p>
  
  <p>Any ideas? (Specifically note: Storyboard.TargetProperty=")  Why must they be in parenthesis?</p>
  
  <pre><code>&lt;Style.Resources&gt;
      &lt;ColorAnimation x:Key="RecordingAnimation" Storyboard.TargetProperty="(Background).(SolidColorBrush.Color)" From="White" To="Blue" Duration="0:0:0.5" AutoReverse="True" RepeatBehavior="Forever"/&gt;
      &lt;ColorAnimation x:Key="StopRecordingAnimation" Storyboard.TargetProperty="(Background).(SolidColorBrush.Color)" To="White" Duration="0:0:0.1"/&gt;
  &lt;/Style.Resources&gt;
  </code></pre>
