title: Permissions on solution files to modify
body: <p>I have project solutions developed in VS2005. It is bound to TFS (Team Foundation Server). I want to convert the solution to VS2008 version, keeping the binding as is, however I am getting an error while converting.</p>
  
  <p>Error message: </p>
  
  <blockquote>
    <p>Solution file "<em>C:\abc\abc.sln</em>" cannot be converted because it cannot be modified. To convert the solution, change the permissions on the solution file to allow modification and reopen it"</p>
  </blockquote>
  
  <p>What permissions do I need on this?</p>
