title: How do I know which version of .NET mono is using?
body: <p>I've been tasked to create an application using <strong>mono/.NET 4.7.2</strong> on linux.</p>
  <p>I've had some experience with .NET Core but I've never used mono before. So I installed mono on a machine running Ubuntu 20.04 but I cannot find the dotnet version that it will be used (since I must use 4.7.2).</p>
  <ol>
  <li>Does it uses my allready existant .NET 5?</li>
  <li>How can I check the version of .NET that will be used by mono?</li>
  <li>More importantly, how can I force to use that specific, 4.7.2,
  version?</li>
  </ol>
  <p>No info from <code>mono --version</code> or <code>csc</code>.</p>
