Answer 1

GetResponseAsync will give you a WebResponse file not the image:

Stream imageStream = downloadedimage.GetResponseStream();

Then you can write to the image file:

byte[] imageData = new byte[imageStream.Length];
using(StreamReader reader = new Streamreader(imageStream))
{
    reader.ReadBytes(imageData, 0, imageData.Length);
}
await FileIO.WriteBytesAsync(imgfile, imageData);
