title: Start-WebAppPool for Powershell 2.0
body: <p>I'm experiencing a problem: I need a command to use on two different shells that gives me the chance to restart a web pool appliction, but only one of these shells is 4.0 (and has the command Start-WebAppPool) and the other one has Ps 4.0...
  What I'm supposed to do?
  Thanks in advance for any help.</p>
