Windows 运行时类型的 .NET Framework 映射
下表列出了 .NET Framework 在 Windows 运行时类型与 .NET Framework 类型之间创建的映射。在用托管代码编写的 Windows 应用商店应用程序中，IntelliSense 显示 .NET Framework 类型而不是 Windows 运行时类型。例如，如果 Windows 运行时方法采用类型为 IVector<string> 的参数，IntelliSense 将显示类型为 IList<string> 的参数。同样，在用托管代码编写的 Windows 运行时组件中，将在成员签名中使用 .NET Framework 类型。当 Windows 运行时元数据导出工具 (Winmdexp.exe) 生成 Windows 运行时组件时，.NET Framework 类型会变为相应的 Windows 运行时类型。
在 Windows 运行时和 .NET Framework 中具有相同的命名空间名称和类型名称的大多数类型是结构（或与结构关联的类型，如枚举）。在 Windows 运行时中，结构没有字段外的成员，并且需要帮助器类型，.NET Framework 会隐藏该类型。这些结构的 .NET Framework 版本的属性和方法可提供隐藏的帮助器类型的功能。
