title: Caliburn.Micro Bootstrapper muted - DisplayRootView is gone
body: <p>I upgraded Caliburn.micro and had a breaking change from 1.0 to 1.1 - method <em>DisplayRootView</em> is gone from Bootstrapper. While in a minor example this did not seem to be an issue, I have a project that remains silent. No "GetInstance" is called, no window appearing, ViewModel is not instantiated. </p>
  
  <p>I am stumped.</p>
  
  <p>What kind of magic am I missing this time round?</p>
