Question

我创建了一个UIViewController派生的基本视图控制器，我的大多数控制器都继承了这个控制器：

public abstract class ViewModelViewController<T> :
  UIViewController where T : ViewModelBase
{
...
}

一旦控制器派生自此基本控制器......

public partial class MainViewController :
  ViewModelViewController<MainPageViewModel>
{
..
}

尝试打开与控制器关联的.xib会导致此错误，该错误无法通过重建，重新启动或任何绝望措施而消失：

唯一的解决方法（实际上不是一个选项）是在编辑xib之前注释掉整个分部类。这是一个停滞不前。

有谁知道真正的解决方法？

this bug的修正将在下一个MonoDevelop更新中。

当关联的控制器派生自基类时，MonoTouch无法打开xib文件
