can't compile WinRT idl file

Question

Hi everyone,

I'm trying to compile WinRT idl files but always got failed , for example , do a syntax check :

midl windows.devices.portable.idl /Zs

told me the following errors :

C:\Program Files\Windows Kits\8.0\include\winrt\IVectorChangedEventArgs.idl(11)
: error MIDL2025 : syntax error : expecting an interface name or DispatchInterfaceName or CoclassName or ModuleName or LibraryName or ContractName or a type specification  near "namespace"
C:\Program Files\Windows Kits\8.0\include\winrt\IVectorChangedEventArgs.idl(11)
: error MIDL2026 : cannot recover from earlier syntax errors; aborting compilation

what's wrong with this ? many thanks.

nice done!
