title: Binding an ObservableCollection.Count to Label with WPF
body: <p>I have a simple <code>Label</code> that should include the bound <code>.Count</code> value of a Property of an <code>ObservableCollection</code>.</p>
  
  <p>The thing is, that the result is always 0 (zero). The same Property is bound to a DataGrid, which works perfectly and even updates if something has changed in the Collection.</p>
  
  <p>What am I doing wrong here?</p>
  
  <p>Here is my code:</p>
  
  <pre><code>&lt;Label ContentStringFormat="Members: {0}"&gt;
      &lt;Label.Content&gt;
          &lt;Binding Path="MembersList.Count" Mode="OneWay" UpdateSourceTrigger="Default" /&gt;
      &lt;/Label.Content&gt;
  &lt;/Label&gt;
  </code></pre>
  
  <p>The Property looks like:</p>
  
  <pre><code>public static ObservableCollection&lt;Mitglied&gt; MembersList { get; set; }
  </code></pre>
