Save DataPackageView.Properties.Thumbnail to disk

Hi,

Try some codes below:

// Lets say the byte array represents the data we want to present as a storage file.
 var fileBytes = new byte[200];var streamReference =DataPackageView.Properties.Thumbnail; 
// Creating the streamed storage file.
var streamedStorageFile = await StorageFile.CreateStreamedFileAsync("MyFileName.jpg", async stream =>
            {
                await stream.WriteAsync(fileBytes.AsBuffer());
                await stream.FlushAsync();
                stream.Dispose();
            }, streamReference);
