title: Missing Project/Item Templates
body: <p>I have Visual Studio 2010 and recently both at home and at work have had an issue with missing projects in the Installed Templates. All that projects and the folder called 'Data' is missing So now SQLDatabase, DataSet, AdoNet Entity Data Model, LinqToSQL, XMLFile, etc...</p>
  
  <p>Fixes tried so far:</p>
  
  <ol>
  <li>uninstall some recent framework addon or related products and it comes back. </li>
  <li>The most common fix is to do 'devenv /installvstemplates' command which has not worked for me. </li>
  <li>check for zip file in 
  C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplates\CSharp\Data\1033 folder and is contains all the appropriate zip files. Also the same for ItemTemplates folder.</li>
  <li>Reinstall - Tried this 3 times no luck even went as far as to remove all reg keys and every folder that had anything to do with VS2010.</li>
  <li>All complete reset of all VS2010 settings and other related commands.</li>
  </ol>
  
  <p>I'm at a lose at what to do next. Beside a complete OS re-install which seems a little drastic. Anyone have a better solution please?</p>
