Use SHGetKnownFolderPath() instead of ApplicationData class to get LocalAppData path

问题

In an desktop-bridge app, I want to find the LocalAppData (or LocalCache) folder of that specific package. I can get the LocalCache folder path with ApplicationData class:

using Windows.Storage;
string appData = ApplicationData.Current.LocalCacheFolder.Path;

Alternatively, if I use SHGetKnownFolderPath function I can also get that same path:

wchar_t* appData;
SHGetKnownFolderPath(FOLDERID_LocalAppData, KF_FLAG_FORCE_APP_DATA_REDIRECTION, NULL, &appData);

So my question: Is it appropriate to use SHGetKnownFolderPath() instead of ApplicationData class? Both give same path in UWP environment. Is there any drawback/cons to use the first one?

You could call any methods before you convert your desktop app to UWP app. Once you converted it successfully, after that, if you want to extend it, for example: Extend your desktop application with modern UWP components, then, you would have to use UWP APIs.
