Unexpected `Specified cast is not valid.` exception (Linq)
<p>Does anyone knows why I can't cast an <code>Int</code> to an <code>UInt</code> by using the Linq extension method <code>Cast&lt;&gt;()</code>?</p>

<pre><code>var myIntList = new List&lt;int&gt;();

myIntList.Add(1);
myIntList.Add(2);
myIntList.Add(3);

var myUIntList = myIntList.Cast&lt;uint&gt;().ToList();
</code></pre>

<p>It throws a <strong>Specified cast is not valid</strong>. When I'm using a <code>Select()</code>, it will work <em>(ofcourse)</em>.</p>

<pre><code>var myIntList = new List&lt;int&gt;();

myIntList.Add(1);
myIntList.Add(2);
myIntList.Add(3);

var myUIntList = myIntList.Select(i =&gt; (uint)i).ToList();
</code></pre>

<p><em>(is it a bug or not implemented feature?)</em></p>
