title: Each Dictionary entry must have an associated key attribute
body: <p>I am programming w Windows 8.1 App using C# and the MVVM-Light Toolkit from GalaSoft.</p>
  
  <p>All I have is the code below:</p>
  
  <pre><code>&lt;Application.Resources&gt;
      &lt;vm:ViewModelLocator x:Key="Locator" xmlns:vm="using:Scedule.ViewModel" /&gt;
  
      &lt;ResourceDictionary&gt;
          &lt;ResourceDictionary.MergedDictionaries&gt;
              &lt;ResourceDictionary Source="Resource Dictionaries/StandardStyles.xaml"/&gt;
          &lt;/ResourceDictionary.MergedDictionaries&gt;
      &lt;/ResourceDictionary&gt;      
  &lt;/Application.Resources&gt;
  </code></pre>
  
  <p>The error "Each Dictionary entry must have an associated key attribute" occurs and only disappears when I either remove  </p>
  
  <pre><code>    &lt;ResourceDictionary&gt;
          &lt;ResourceDictionary.MergedDictionaries&gt;
              &lt;ResourceDictionary Source="Resource Dictionaries/StandardStyles.xaml"/&gt;
          &lt;/ResourceDictionary.MergedDictionaries&gt;
      &lt;/ResourceDictionary&gt; 
  </code></pre>
  
  <p>or</p>
  
  <pre><code>    &lt;vm:ViewModelLocator x:Key="Locator" xmlns:vm="using:Scedule.ViewModel" /&gt;
  </code></pre>
  
  <p>Can anyone tell me what the problem here is? </p>
