title: The ‘from’ Keyword is not supported in this version of language
body: <p>While i am running following command in powershell in windows server 2016 : </p>
  
  <pre><code>FROM microsoft/windowsservercore RUN dism /online /enable-feature /all /featurename:iis-webserver /NoRestart
  </code></pre>
  
  <p>I am getting:</p>
  
  <blockquote>
    <p>The ‘from’ Keyword is not supported in this version of language”
    error.</p>
  </blockquote>
  
  <p>Please help me in getting this issue solved.</p>
  
  <p><strong>[EDIT]</strong></p>
  
  <p>Actually, I was wrong running FROM keyword in PowerShell. This will be dockerfile. Also when copy above from command in docker file and run:</p>
  
  <pre><code> *docker build -t windowsserveriis .*
  </code></pre>
  
  <p>then I am getting:</p>
  
  <blockquote>
    <p>ltsc2019: Pulling from windows/servercore no matching manifest for
    windows/amd64 10.0.14393 in the manifest list entries error.</p>
