GetTempFileName for metro apps

I need to generate the unique temporary filenames in my application using c++ (WINRT/Metro). As I see, Win32 API GetTempFileName is marked for use on desktop only.

What is its equivalent for metro style apps?

Yo can achieve this by saving a file in temporary storage, and naming them via a GUID. Example:

// Get temporary storage folder    
var tempFolder = Windows.Storage.ApplicationData.Current.TemporaryFolder;

// generate unique filename
var filename = Guid.NewGuid().ToString();
StorageFile myFile = await tempFolder.CreateFileAsync(filename, CreationCollisionOption.ReplaceExisting);
