    Hola, tengo problemas al abrir un nuevo proyecto de windonws phone
    1.- abro el visual 2012
    2.- Ctrl+Mayus+N (nuevo proyecto)
    3.- Elijo plantillas - C# - Aplicacion de windonws phone
    4.- framework 4.5 aparece por defecto 
    5.- luego, elijo windons phone OS 8.0 ó  windons phone OS 7.1
    6.- me sale el error que publique arriba, cuando carga el diseñador (MainPage.xaml)
    * (el simulador solo funciona con O.S 7.1 funciona)
