BitmapImage to StorageFile in UWP

Question

I have a BitmapImage by doing this:

var bitmap = new BitmapImage(new Uri(url, UriKind.Absolute))

But, because I am working with a Cortana App, I need to use StorageFile as the image type (very stupid imo, but that is how it is)

So, how can I transform that bitmap into the StorageFile I need, or how can I download an image through an URL into a StorageFile, because

StorageFle.GetFileFromApplicationUriAsync(Uri uri)

keeps popping an exception of "Value does not fall within the specified range"

Any help would be very much appreciated, thanks!

StorageFle.GetFileFromApplicationUriAsync is used to get app resource.

To download a remote Uri as a StorageFile, use StorageFile.CreateStreamedFileFromUriAsync.

var path = "https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-logo.png";
var file = await StorageFile.CreateStreamedFileFromUriAsync(Path.GetFileName(path), 
    new Uri(path), null);

You can also save the file to disk check if it is downloaded correctly.

await file.CopyAsync(ApplicationData.Current.LocalFolder);
