title: Autofac with string configuration but without Microsoft.Extensions.Configuration
body: <p>The documentation for Autofac has a section for registering components with XML or JSON but it relies on Microsoft.Extensions.Configuration. Is there a way to do without without loading the string into that extension first?</p>
  
  <p>My environment is based on the latest Xamarin.Forms and Autofac.</p>
  
  <p>Cheers,
  Luiz</p>
