Windows :: Storage :: ApplicationData ::当前未在C中找到

我修改C GrayscaleTransform以包含以下代码.

但是,我的C代码无法找到命名空间Windows :: Storage.

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

我需要做任何其他设置吗？

我可以通过打开Consume Windows Runtime Extension来编译它.

但通过这样做,它将给我额外的链接错误和警告.

warning LNK4197: export 'DllGetActivationFactory' specified multiple times; using first specification 
warning LNK4197: export 'DllCanUnloadNow' specified multiple times; using first specification
warning LNK4197: export 'DllGetActivationFactory' specified multiple times; using first specification

error LNK2005: _DllCanUnloadNow@0 already defined in dllmain.obj 
error LNK1169: one or more multiply defined symbols found

注释掉DllCanUnloadNow会产生运行时错误.

我得到一个运行时休息
