title: Comment Based Help not displayed in Powershell
body: <p>I am trying to implement Comment Based Help as described <a href="https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_comment_based_help?view=powershell-5.1" rel="nofollow noreferrer">here</a> with Powershell 5.1 on Windows Server 2016.</p>
  
  <p>The script I am using is called blah.ps1:</p>
  
  <pre><code>&lt;#
  .DESCRIPTION
  blah blah
  #&gt;
  function Blahblah
  {
  }
  </code></pre>
  
  <p>In Powershell, I can load the script:</p>
  
  <pre><code>.\blah.ps1
  </code></pre>
  
  <p>But when I ask for help on this function using:</p>
  
  <pre><code>Get-Help Blahblah
  </code></pre>
  
  <p>Powershell only reports an error:</p>
  
  <pre><code>Get-Help : Get-Help could not find Blahblah in a help file in this session. To download updated help topics type: "Update-Help". To get help online, search for the help topic in the TechNet library at http://go.microsoft.com/fwlink/?LinkID=107116.

  <p>I am assuming that Get-Help can be used with the custom help comments. What am I missing?</p>
