mvvm - How to use Xamarin Forms Labs ViewModel from XAML? -

i tried mvvm implementation xamarin.forms project , xlabs' viewmodel looked best me. not know how make a, example, masterdetail xaml page it. testpage derived viewbase class. first approach this:

<?xml version="1.0" encoding="utf-8" ?> <toolkit:baseview xmlns="http://xamarin.com/schemas/2014/forms"                   xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"                   xmlns:toolkit="clr-namespace:xlabs.forms.mvvm;assembly=xlabs.forms"                   x:class="xlabs.sample.pages.mvvm.mvvmsamplepage"                   title="mvvm">  <toolkit:baseview.content>         <stacklayout>             <button text="{binding navigatetoviewmodelbuttontext}" command="{binding navigatetoviewmodel}" />         </stacklayout>     </toolkit:baseview.content> </toolkit:baseview> 

but inside baseview.content element can't put page. how use masterdetailpage or tabbedpage within it?
