my project was created with the visual studio tempalte, support desktop ,android and web.

MainViewModel:

public class MainViewModel : ViewModelBase
{
    ViewModelBase _CurrentViewModel;

    public ViewModelBase CurrentViewModel
    {
        get { return _CurrentViewModel; }
        private set { this.RaiseAndSetIfChanged(ref _CurrentViewModel, value); }
    }

    public MainViewModel() 
    {
        _CurrentViewModel=new LoginViewModel();
    }
}

MainView.axaml:

  <Design.DataContext>
    <!-- This only sets the DataContext for the previewer in an IDE,
         to set the actual DataContext for runtime, set the DataContext property in code (look at App.axaml.cs) -->
    <vm:MainViewModel />
  </Design.DataContext>
    <Grid>
        <TransitioningContentControl Content="{Binding CurrentViewModel}"></TransitioningContentControl>
