每次尝试在 VS 2013 中打开 *.storyboard 文件时，我都会在下面遇到异常，并且永远无法打开它。但是，我可以将 VS 中的 Xamarin.iOS 项目部署到 iPhone。
以下是我的系统详细信息：
- Windows 7 主机，OS X 10.9.5 来宾通过 VirtualBox
- 我可以从主机 ping 客人，反之亦然。
- 我可以将 VS 中的 Xamarin.iOS 项目部署到 iPhone。
- Windows 防火墙已禁用。
Windows 设置
- Windows 7，VS 2013，Xamarin 3.9.2，Xamarin.iOS 8.6.1.0，
Mac 设置
- Mac OS X 10.9.5、Xcode 6.1.1、Xamarin.iOS 8.6.1.20、Xamarin Studio 5.7.1
下面的例外（在VS中）：
