windows-phone-7 – 在Windows Phone 8中,我不断收到System.WInd

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);


        }

和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,我没有得到此异常.

任何帮助,将不胜感激.

更新：
我添加了整个异常消息,它是否有助于查明问题？
