windows-phone-7 - 在 Windows Phone 8 中，我不断收到 System.WIndows.Markup.XamlParseException

Question

我得到的错误信息是

A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in System.Windows.ni.dll

调用堆栈可追溯到这段代码。

 public MainPage()
        {
            **InitializeComponent();**
            this.Init();

            // Set the data context of the listbox control to the sample data
            DataContext = App.ViewModel;
            this.Loaded += new RoutedEventHandler(MainPage_Loaded);


        }

以及 InitializeComponent() 行上的错误。

public void InitializeComponent() {
        if (_contentLoaded) {
            return;
        }
        _contentLoaded = true;
        System.Windows.Application.LoadComponent(this, new System.Uri("/App;component/MainPage.xaml", System.UriKind.Relative));
        this.LayoutRoot = ((System.Windows.Controls.Grid)(this.FindName("LayoutRoot")));
        this.SSIDTextBox = ((System.Windows.Controls.TextBox)(this.FindName("SSIDTextBox")));
        this.PasswordTextBox = ((System.Windows.Controls.TextBox)(this.FindName("PasswordTextBox")));
        this.Auth_ListPicker = ((Microsoft.Phone.Controls.ListPicker)(this.FindName("Auth_ListPicker")));
        this.SaveButton = ((System.Windows.Controls.Button)(this.FindName("SaveButton")));
        this.GenerateButton = ((System.Windows.Controls.Button)(this.FindName("GenerateButton")));
        this.QRImage = ((System.Windows.Controls.Image)(this.FindName("QRImage")));
        this.Profiles= ((System.Windows.Controls.ListBox)(this.FindName("Profiles")));
    }
}

在将 WP 7.1 转换为 WP8 之前，我没有收到此异常。

任何帮助，将不胜感激。

更新 :
我添加了整个异常消息，它有助于查明问题吗？

只需在 list 文件中添加权限即可。

转到 WMAppmanifest.xml

选择“能力”选项卡

现在检查“ID_CAP_MAP”
