title: changing output of the console.WriteLine
body: <p>During my job interview, interviewer asked me to change the the console output to print "B" without touching the main method and console!<br>
  is this possible? (I tried to change the entry point,but it was not correct) 
  I have no idea how to answer this question </p>
  
  <pre><code> class Program
    {
          static void Main(string[] args)
          {
              Console.WriteLine("A");
          }
    }
  </code></pre>
