VC++ property page not loading

I trying to create a new custom property page based on the info found on this blog http://blogs.msdn.com/b/vsproject/archive/2009/06/18/platform-extensibility-part-2.aspx

<?xml version="1.0" encoding="utf-8"?><ProjectSchemaDefinitions
    xmlns="http://schemas.microsoft.com/build/2009/properties"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:sys="clr-namespace:System;assembly=mscorlib"><Rule
    Name="MyConfiguration"
    DisplayName="My Configuration"
    Order="10"
    PageTemplate="generic"
    Descrition="My Configuration"><Rule.Categories><Category Name="General" DisplayName="General" Description="General"/></Rule.Categories><Rule.DataSource><DataSource Persistence="ProjectFile" Label="MyConfiguration"/><Rule.DataSource><StringProperty Name="MyOutDir"
                    DisplayName="My Output Directory"
                    Subtype="folder"
                    Category="General"
                    Default="$(ProjetDir)"/></Rule></ProjectSchemaDefinitions>

Then in my VC project I include it like

<ItemGroup><PropertyPageSchema Include="$(MSBuildThisFileDirectory)\MyConfiguration.xml"/></ItemGroup>

Then load my project with Visual Studio 2012/2013 but I cannot see "My Configuration" in the project properties, can some body point me what I doing wrong?
