Compiler doesn't find namespace, but Visual Studio doesn't complain

[kuch3n]

The NativeMethods.txt contains following lines:

RegisterDeviceNotification
DEV_BROADCAST_HDR
DBT_DEVTYP_*
DEVICE_NOTIFY_WINDOW_HANDLE

From references following code is available:

Windows.Win32.DEV_BROADCAST_HDR.g.cs

Code for which the compiler is complaining: `private Windows.Win32.UI.WindowsAndMessaging.DEV_BROADCAST_HDR_DEVICE_TYPE broadcast;` with error ` error CS0234: The type or namespace name 'UI' does not exist in the namespace 'Windows.Win32' (are you missing an assembly reference?)`

EDIT

PInvoke only contains following constants, which doesn't match the docs
