visual studio XAML designer not loading
提问by Reza Shayestehpour
I'm developing Windows phone apps on my Mac Book Pro Retina (late 2013) on a virtual machine using Parallels 9. I have Visual Studio 2012 and Windows phone 8 SDK installed and everything works fine writing code and testing it on my Lumia phone. The problem is that the XAML designer doesn't load i.e. I get the following error:
我正在使用 Parallels 9 在虚拟机上的 Mac Book Pro Retina（2013 年末）上开发 Windows 手机应用程序。我安装了 Visual Studio 2012 和 Windows phone 8 SDK，一切正常，可以在我的 Lumia 手机上编写代码并进行测试。问题是 XAML 设计器没有加载，即我收到以下错误：
System.InvalidOperationException The document failed to open.
at Microsoft.Expression.DesignSurface.DesignerService.CreateDesigner(IHostSourceItem item, IHostTextEditor editor, CancellationToken cancelToken)
at Microsoft.Expression.DesignHost.IsolatedDesignerService.IsolatedDesignerView.CreateDesignerViewInfo(CancellationToken cancelToken)
Next to this error message, which is displayed instead of the designer, there's a button to reload the designer. But when I press it, it takes forever and gets no results.
在显示而不是设计器的此错误消息旁边，有一个用于重新加载设计器的按钮。但是当我按下它时，它需要很长时间并且没有结果。
I have posted my question in the Microsoft forumbut it seems like a ghost town down there.
我已经在 Microsoft论坛上发布了我的问题，但那里似乎是一个鬼城。

I also got an infinitely loading Designer. I solved it by deleting the UserControl and recreating it via source control.
我还得到了一个无限加载的设计器。我通过删除 UserControl 并通过源代码管理重新创建它来解决它。
