title: Prism - ViewModel-First, Navigation API, with Scoped Regions
body: <p>Found a few examples which attempted to couple scope region functionality with Prism's Navigation API, but I don't quite understand how I can put this together using a viewmodel-first approach with implicit datatemplates - each wrapping a UserControl.</p>
  
  <p>Some of my UserControls are wrapped within multiple DataTemplates. These UserControls specify their own regions.</p>
  
  <p>My main shortcoming, is my inability to grasp how it's possible to grab a reference to the Local RegionManager during a Navigation request. How can I notify Prism to create the scoped region, if necessary, and Import the local RegionManager instance inside the Constructor of a child ViewModel which initiates a Navigation request?</p>
  
  <p>Any help?</p>
