title: WPF Caliburn.micro how to get instance per request from CompositionContainer
body: <p>I'm using caliburn.micro and I've configured Bootstrapper as shown here: <a href="https://caliburnmicro.codeplex.com/wikipage?title=Customizing%20The%20Bootstrapper&amp;referringTitle=Documentation" rel="nofollow">bootstrapper configuration</a>, but unfortunatelly I can't find a way to request exported value as a new instance - container always returns singleton.</p>
  
  <p>I've been working also with PhoneContainer (WindowsPhone) and it has great features as PerRequest and Singleton. Is there something like that for WPF?</p>
