title: SQLite.WP81 extension SDK installs on VS2013 U2 but unable to reference assembly in WP 8.1 project
body: <p>After installing the SQLite.WP81 extension SDK on Visual Studio 2013 Update 2, the SQLite for Windows Phone assembly does not appear in the list of Extensions in the Windows Phone 8.1 tab.</p>
  
  <p>There is a discussion on the <a href="http://visualstudiogallery.msdn.microsoft.com/5d97faf6-39e3-4048-a0bc-adde2af75d1b">SQLite for Windows Phone 8.1 download page in the Visual Studio Gallery</a> where another developer seems to have the same issue. Another developer suggests manually installing the extension, but that made no difference. (And that advice seems suspect as it appears this extension is now installed under C:\Program Files (x86)\Microsoft SDKs\WindowsPhoneApp\v8.1\ExtensionSDKs\SQLite.WP81\3.8.6)</p>
  
  <p>It seems the extension has failed to register itself as an extension SDK with Visual Studio.</p>
  
  <p>Anyone with ideas of how to fix this? </p>
  
  <p><strong>EDIT: Things have advanced a bit</strong> </p>
  
  <p><s>I moved the SQLite.WP81 folder from the C:\Program Files (x86)\Microsoft SDKs\WindowsPhoneApp\v8.1\ExtensionSDKs\SQLite.WP81\ to C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v8.1\ExtensionSDKs\SQLite.WP81\, updated the paths in the \SQLite.WP81\3.8.6\extension.vsixmanifest and \SQLite.WP81\3.8.6\DesignTime\CommonConfiguration\neutral\SQLite.WP81.props files to reflect the new location and the package appeared. </p>
  
  <p>This is weird and great at the same time. Manually hacking the SDK seems odd. But it is progress.</s></p>
  
  <p>Now, the problem is SQLite.WP81 wants some SDK called Microsoft.VCLibs and that does not appear in the Resource Manager. Searching the web has been fruitless so far. </p>
  
  <p>Does anyone have a clue where to find the Microsoft.VCLibs?</p>
