Xamarin Unified IOS WKWebView崩溃

我在使用新的Xamarin Unified iOS API的WKWebView时遇到了一些麻烦，它使用EXC_BAD_ACCESS（SIGABRT） - KERN_INVALID_ADDRESS异常加载时崩溃（必须通过电话日志查找，没有显示在视觉工作室里我可能会遇到这样的问题，下面的代码似乎是一个不错的代码，它在传统的API中工作得很好（尽管由于API差异而做了小的改动）。 3个WKWebView线，以及将它添加到控制器的线，应用程序运行。注意：窗口，控制器和WKWebView都是appdelegate类的所有参数Xamarin Unified IOS WKWebView崩溃

public override bool FinishedLaunching(UIApplication app, NSDictionary options) 
{ 
    Window = new UIWindow(UIScreen.MainScreen.Bounds); 
    Window.BackgroundColor = UIColor.White; 
    Window.MakeKeyAndVisible(); 

    Controller = new UIViewController(); 
    Controller.View.AutosizesSubviews = true; 
    Window.RootViewController = Controller; 

    var wkConfig = new WKWebViewConfiguration(); 
    WKWebView = new WKWebView(new CGRect(0, 20, (float)UIScreen.MainScreen.Bounds.Width, (float)UIScreen.MainScreen.Bounds.Height - 20), wkConfig); 
    WKWebView.LoadRequest(new NSUrlRequest(new NSUrl(RazorRouting.GetRootUrl()))); 

    Controller.View.AddSubview(WKWebView); 

    return true; 
}

更多信息：查看设备系统日志，在创建webview的行上出现“断言失败：12B411：libxpc.dylib”错误。我可能做错了创建webview？ – Patrick 2014-10-28 14:25:25

这可能是由错误在Visual Studio生成过程中造成的Xamarin.iOS统一的API项目引起的问题对于特殊的统一nfloat原始类型（请参阅https://bugzilla.xamarin.com/show_bug.cgi?id=23868#c14）。

我已经为此WKWebView崩溃专门提交了第二个错误：https://bugzilla.xamarin.com/show_bug.cgi?id=24151。我怀疑这个新bug最终会被解决为旧bug的复本。
