title: Automapper DynamicMap failing to map Lists of anonymous types
body: <p>I have the following snippet of code.</p>
  
  <pre><code>var files = query.ToList();
  var testFile = Mapper.DynamicMap&lt;EftFileDto&gt;(files.First());
  var filesDto = Mapper.DynamicMap&lt;List&lt;EftFileDto&gt;&gt;(files);
  </code></pre>
  
  <p><code>testFile</code> has a properly mapped value, but filesDto is empty.</p>
  
  <p>It appears dynamicMap works on individual items, but not lists?</p>
  
  <p><code>files</code> is a List of anonymous objects.</p>
  
  <p><strong>EDIT</strong>: It doesn't work if I use Arrays either.  I can get it to work, but ...</p>
  
  <pre><code>        var filesDto = query.Select(Mapper.DynamicMap&lt;EftFileDto&gt;).ToList();
  </code></pre>
