Trouble with UriMapper

Question

je me suis vers le haut de la navigation et en cours d'exécution dans ma demande, mais je voulais cacher le vrai chemin de vues si je l'ai écrit ce UriMapper:

<Application 
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
x:Class="MyApplication.App" 
    xmlns:navcore="clr-namespace:System.Windows.Navigation;assembly=System.Windows.Controls.Navigation"> 
<Application.Resources> 
    <!-- Resources scoped at the Application level should be defined here. --> 
     <navcore:UriMapper x:Key="uriMapper"> 
      <navcore:UriMapping Uri="{}{page}" MappedUri="/Views/{page}.xaml" /> 
     </navcore:UriMapper> 
</Application.Resources> 
</Application> 

Voici mon bouton de navigation cliquez sur le code de l'événement:

private void NavigateButton_Click(object sender, RoutedEventArgs e) 
    { 
     Button btn = sender as Button; 
     string uri = btn.Tag.ToString(); 

     this.ContentFrame.Navigate(new Uri(uri, UriKind.RelativeOrAbsolute)); 
    } 

Et voici XAML d'un bouton:

<Button Content="Home" Click="NavigateButton_Click" Tag="Home" HorizontalAlignment="Center" VerticalAlignment="Center" Width="100" Height="30" /> 

Cependant, lorsque je clique sur un bouton, je reçois t son erreur:

Content for the URI cannot be loaded. The URI may be invalid. 

A cette ligne:

this.ContentFrame.Navigate(new Uri(uri, UriKind.RelativeOrAbsolute)); 

Qu'est-ce que je fais mal?

EDIT:

Plus fichiers XAML ... MainPage.xaml:
