title: XAML Int to boolean converter
body: <p>I need to create MultiDataTrigger with condition to check if my ObservableCollection Count property &lt;> 0.</p>
  
  <p>So I want to convert Count value of my collection to boolean.</p>
  
  <p>How can I do that?</p>
  
  <p>Something like:</p>
  
  <pre><code>&lt;Condition Binding="{Binding Path=MyCollection.Count, Converter=Int32CollectionConverter, ConverterParameter=&lt;what should be there?&gt;}" Value="true" /&gt;
  </code></pre>
