Ciao
Stoa sbattendo la testa da diversi giorni, sto facendo un refactoring di un progetto silverlight funzionante, per poter cambiare semplicemente dei nomi del progetto e dei namespace. Nel nuovo progetto ho ricreato una pagina alla volta ricopiando lo xaml e il c# del codebehind corrispondente. Ora non capisco perchè mia dà questo errore:

Errore6errore imprevisto dell'attività "ValidateXaml".
