我想知道是哪个原因造成的，是我的错还是Windows SDK的。
经过几天的思考，试图找到解决方案，
解决方法非常简单：namespace System {
typedef Windows.Foundation.IClosable IDisposable;
}
namespace MyComponent.MyNamespace {
interface IMyInterface : IInspectable requires System.IDisposable {
...
}
}
上面的 typedef 可以放入单独的共享 .idl 文件中，只要需要外部接口派生，就可以包含该文件。
更新(2020/06/06(：一年和几次SDK更新后，问题仍然存在。 :(
此外，我遇到了一种特定情况，当我的修复效果不佳时 - 当一个 cppwinrt WRC 项目依赖于另一个 cppwinrt WRC 项目时。显然，typedef 在导入的 .winmd 中成为原始类型，因此引用的项目编译良好，但引用项目因相同的旧"内部编译器问题"而失败。不幸的是，您无法使用上述包含来修复它，因为导入的 .winmd 是在项目 .idl 之前处理的。
我已经进一步调查了这个问题，这是我发现的：
- 错误不仅发生在
Windows.Foundation.IClosable本身，而且发生在需求树下某处的任何其他接口 - 从此类接口派生运行时类时不会发生错误(仅发生在接口"继承"中(
- 解决方法非常简单且非常相似：如果您键入这样的接口而不是直接使用它 - 一切都会编译得很好。
我想知道是哪个原因造成的，是我的错还是Windows SDK的。
这是最新 Windows SDK 附带的 MIDL 编译器中的一个已知错误。
