title: Using a Windows 8.0 Extension SDK component built using Visual C++ 2012 in a Windows 8.1 app
body: <p>I have a Windows 8 app built using Visual Studio 2012.  This app also uses a 3rd party component (packaged as an <a href="http://msdn.microsoft.com/en-us/library/jj127117.aspx" rel="nofollow">Extension SDK</a>) also built using Visual Studio 2012.  Since this component is written using C++, the Extension SDK has a dependency on Microsoft.VCLibs.110.00 (Visual C++ 2012 Runtime).</p>
  
  <p>Now, I am trying to rebuild this app for Windows 8.1.  When I try to build this project using using Visual Studio 2013, I see the following behavior (using Bing Maps SDK only as an example, this applies to any other SDK built using VS 2012):</p>

  <h1>WACK Errors</h1>
  
  <p>If I am somehow able to move forward (after changing the SDKManifest.xml of the Bing Maps SDK), I am able to create an app package.  When I run <a href="http://msdn.microsoft.com/en-us/library/windows/apps/hh694081.aspx" rel="nofollow">WACK</a> on my app, I get the following error:</p>
  
  <p><em>cppapp takes a dependency on Microsoft Visual C++ Runtime Package (Microsoft.VCLibs.110.00) framework but is missing the framework dependency declaration in the manifest.</em></p>
