title: which version of PowerShell ISE is required for join-object?
body: <p>When I am trying to use <code>Join-Object</code> it is throwing the following error:</p>
  
  <blockquote>
    <p>The term 'join-object' is not recognized as the name of a cmdlet,
    function, script file, or operable program. Check the spelling of  the
    name, or if a path was included, verify that the path is correct and
    try again.</p>
  </blockquote>
  
  <p>I am not sure why it is throwing this error.</p>
  
  <p>My current version of Windows PowerShell is 3.0.</p>
