title: Failing to localize WIndows 8 App with Multilingual App Toolkit
body: <p>I'm trying to localize my Windows 8 App with the Multilingual App Toolkit.
  And for that I tried to follow this explanation to the point:</p>
  
  <p><a href="http://channel9.msdn.com/posts/Build-Multi-language-apps-using-the-Multilingual-App-Toolkit" rel="nofollow">http://channel9.msdn.com/posts/Build-Multi-language-apps-using-the-Multilingual-App-Toolkit</a></p>
  
  <p>but it fails with the following Output:</p>
  
  <pre><code>1&gt;  Multilingual App Toolkit build started.
  1&gt;  Merge of Loc PRI file failed calling makepri.exe: '0x80073B08'
  1&gt;  Multilingual App Toolkit build completed with errors.
  </code></pre>
  
  <p>I can't find anything for <code>0x80073B08</code>. 
  If I remove all xlf language files from the project it compiles, is able to launch and to build a store package.
  But as soon as there is any language file included it failes to build with the error above.</p>
  
  <p>Any Ideas?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I'm using c# and a single resw file.</p>
  
  <p>Everything works as long as I don't include any xlf files.</p>
  
  <p>There are no duplicate keys (except partly duplicate like "MyButton.Text", "MyButton.[using:Windows.UI.Xaml.Controls]ToolTipService.ToolTip")</p>
  
  <p><strong>EDIT2:</strong></p>
  
  <p>Seems like the real problem is the extension format, e.g.:</p>
  
  <pre><code>ClearNotesButton.[using:Windows.UI.Xaml.Controls]ToolTipService.ToolTip
  </code></pre>
  
  <p>or</p>
  
  <pre><code>AddPageButton.[using:Windows.UI.Xaml.Automation]AutomationProperties.Name
  </code></pre>
  
  <p>if I use those makepri throws the exception above.
  Does this mean I can't set the Tooltip and the Text of a Button via the x:Uid mechanism?</p>
