title: Cannot find resource to load in dictionary
body: <p>I'm trying to load a xaml file inside a <code>ResourceDictionary</code> what I did is create a Dictionary like this:</p>
  
  <pre><code>ResourceDictionary dict = new ResourceDictionary();
  </code></pre>
  
  <p>and then:</p>
  
  <pre><code>dict.Source = new Uri("..\\Resources\\Languages\\en-EN.xaml", UriKind.Relative);
  </code></pre>
  
  <p>now I've the following application folders structure:</p>
  
  <pre><code>AppName
      Resources
           Languages
                 en-EN.xaml 
                 it-IT.xaml
  </code></pre>
  
  <p>unfortunately I get this error:</p>
  
  <blockquote>
    <p>cannot find the resource 'resources/languages/en-en.xaml'</p>
  </blockquote>
  
  <p>but the resource exist, why happen this?</p>
