List.Count resets to zero
<p>I want to create a list with 11 entries, but <code>List.Count</code> resets to zero after this code. </p>

<p>There are no entries added to the list. What is wrong?</p>

<pre><code>List&lt;Animation&gt; animations = new List&lt;Animation&gt;();

animations[0] = new Animation(new List&lt;Rectangle&gt;(10), 
                                     Content.Load&lt;Texture2D&gt;("pictures"), 
                                     TimeSpan.FromSeconds(2), 
                                     Animation.Animationsablaeufe.vorrück);
</code></pre>
