title: Errors in Generated Files for WinRT XAML DirectX Universal App
body: <p>I started a project from the DirectX and XAML template and made some small edits to the Direct3D-only portion of the project.</p>
  
  <p>Now I get a number of errors in the xamltypeinfo.g.cpp file, stating that the <code>Common::NavigationHelper</code> class doesn't exist. Hovever I can validate that it's definitely a class included in the template, but it looks like whatever generated these files didn't include it.</p>
  
  <p>I don't want to go messing around with generated files, and I haven't touched any of the XAML code at all in the template. </p>
