My C++ code, which is part of Media Foundation Transform tend to able to run in Windows Store App (Metro)

I modify the C++ GrayscaleTransform to include the following code.

However, my C++ code fails to locate namespace Windows::Storage.

LPCWSTR zPath = Windows::Storage::ApplicationData::Current->TemporaryFolder->Path->Data();

Is there any additional settings I need to do?

I can make it compiled, by turning on Consume Windows Runtime Extension.

But by doing this, it will give me additional linking error and warnings.

Comment out DllCanUnloadNow will produce runtime error.
