TypeLoadException從用戶控件

Question

導航到一個頁面我有這樣的代碼在我的用戶：

Private Sub tap(sender As Object, e As TappedRoutedEventArgs) Handles Me.Tapped 
    Try 
     CType(Window.Current.Content, Frame).Navigate(GetType(calendar_day)) 
     'calendar_day is a page in project' 
    Catch ex As Exception 
     Debug.WriteLine(ex.HelpLink) 
     Debug.WriteLine(ex.HResult) 
     Debug.WriteLine(ex.InnerException) 
     Debug.WriteLine(ex.Message) 
     Debug.WriteLine(ex.Source) 
     Debug.WriteLine(ex.StackTrace) 
    End Try 
End Sub 

輸出：

A first chance exception of type 'System.TypeLoadException' occurred in Organize.exe

我試圖清理，改造，建設兩個x64和x86，但沒有什麼幫助。

我第一次創建calendar_day爲BlankPage1，然後重命名文件和類。但是在calendar_day.xaml中，我離開了x:Class="Organize.BlankPage1"。
