title: Directory.SetCreationTime Error
body: <p>Whenever I call Directory.SetCreationTime I get "The process cannot access the file 'C
  :\whatever' because it is being used by another process."  The error occurs all the time for every directory.  My program is a C# console app.  This is the simplified version:</p>
  
  <pre><code>using System;
  namespace test
  {
   class test
   {
    static void Main(string[] args)
    {
     System.IO.Directory.SetCreationTime("C:\\temp", DateTime.Now);
    }
   }
  }
  </code></pre>
  
  <p>Thanks in advance for your help!</p>
