从usercontrol导航到页面时出现TypeLoadException

Question

我在Usercontrol中有这个代码：

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

输出：

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

Could not find Windows Runtime type 'Windows.Foundation'.

at Organize.day_btn.clicked(Object sender, TappedRoutedEventArgs e)

我已经尝试过清理，重建，构建x64和x86，但没有任何帮助。

Answer 1

我首先将calendar_day创建为BlankPage1，然后重命名为file和class。但是在calendar_day.xaml中，我离开了x:Class="Organize.BlankPage1"。
