title: log4net and "with try" F#
body: <p>I am using log4net in a try with expression and it is not working. I think something is missing but I don't know what.
  Here is my code :</p>
  
  <pre><code>let clusterIDArray = try
                           myfunction
                       with
                           log.Fatal("my function is not working")   
  
  
  log.Debug("my function is working")
  </code></pre>
  
  <p>Any ideas?</p>
