title: Culture-specific resource files not being generated in Visual Studio 2013 SP2
body: <p>I have created an MVC 5 project in VS2013 (with Update 2).  If I add a resource file to the App_GlobalResources folder, it correctly generates the corresponding .designer.cs file when I save.  </p>
  
  <p>However, if I make a copy of the resource file and <strong>include a culture in the name</strong>, e.g. Resource.fr-FR.resx, the designer file is always empty.</p>
  
  <p>Steps to replicate:</p>
  
  <ol>
  <li>Create an App_GlobalResources folder (right-click project > Add ASP.NET Folder > ...)</li>
  <li>Right click this folder > Add > Resources file</li>
  <li>Accept default name (Resource1)</li>
  <li>Make a copy (you should have Resource1 - Copy.resx)</li>
  <li>Rename the copy to Resource1.fr-FR.resx</li>
  <li>Inspect the .designer.cs file - it is empty</li>
  </ol>
  
  <p>Maybe this has something to do with the custom tool (GlobalResourceProxyGenerator) and file names with a dot/period? I'm pretty new to localization so I'm probably doing it wrong!</p>
