title: How to work with C++ Windows Runtime Component and AnyCPU target?
body: <p>I made a <em>Windows Runtime Component</em> with VS2013, using C++/CX and targeting Universal Apps. Therefore, I now have 5 DLL files:</p>
  
  <ul>
  <li><strong>Windows</strong>
  <ul>
  <li><strong>ARM</strong>
  <ul>
  <li>MyLib.winmd</li>
  <li>MyLib.dll</li>
  </ul></li>
  <li><strong>x86</strong>
  <ul>
  <li>MyLib.winmd</li>
  <li>MyLib.dll</li>
  </ul></li>
  <li><strong>x64</strong>
  <ul>
  <li>MyLib.winmd</li>
  <li>MyLib.dll</li>
  </ul></li>
  </ul></li>
  <li><strong>WindowsPhone</strong>
  <ul>
  <li><strong>ARM</strong>
  <ul>
  <li>MyLib.winmd</li>
  <li>MyLib.dll</li>
  </ul></li>
  <li><strong>x86</strong>
  <ul>
  <li>MyLib.winmd</li>
  <li>MyLib.dll</li>
  </ul></li>
  </ul></li>
  </ul>
  
  <p>My customer wants to use this library in a Windows 8.1 project. He told me that he cannot use the lib with a project targeting "AnyCPU", which is normal since each DLL is for a single platform. However, what should I tell him? How should he create his project in order to get a package working on each platform?</p>
