title: no windows phone 7 combo box found
body: <p>I am using express edition visual studio 2010 for windows phone 7 , 7.1 sdk. I am trying a tutorial over at <a href="http://create.msdn.com/en-US/education/quickstarts/Data_Binding_to_Controls#BindingSingleItem" rel="nofollow">app hub</a> but when i reach the combo example, the combo box doesn't show in the xaml and not even when i run the app.</p>
  
  <p>I looked over in the Toolbox editor in VS and also the combo box isn't there.</p>
  
  <p>Is combo box in the silverlight toolkit? (i don't have it installed, that would justify why i can't see it in the toolbox). If no, why can't i see it? The code in the example (XAML) for the combobox is :</p>
  
  <pre><code>&lt;ComboBox x:Name="ComboBox1" ItemsSource="{Binding}"
  Foreground="Black" FontSize="18" Height="50" Width="400"/&gt;
  </code></pre>
  
  <p>which looks fine to me.</p>
