You need to bind the View.Model property, which:
- displays the correct view for representing VM
- binds a DataContext view to a VM
- invokes a view in the ContentControl Content property
Example:
<ContentControl cal:View.Model="{Binding CurrentPresenter}" />
Caliburn v1.x, Caliburn v2 Caliburn.Micro IPresesenterManager IConductor ( ), :
<ContentControl cal:View.Model="{Binding ActiveItem}" />
