title: WPF localization with ResourceDictionary
body: <p>At the moment I integrate the current strings like this:</p>
  
  <pre><code>&lt;Window.Resources&gt;
      &lt;ResourceDictionary&gt;
          &lt;ResourceDictionary.MergedDictionaries&gt;
              &lt;ResourceDictionary Source="lang/Dictionary.en-US.xaml" /&gt;
          &lt;/ResourceDictionary.MergedDictionaries&gt;
      &lt;/ResourceDictionary&gt;
  &lt;/Window.Resources&gt;
  </code></pre>
  
  <p>Is there a possibility to do this dynamically in my code behind files?</p>
