In the question it says: The GetData() method must return a string value that contains the first line of the response from the web service. But the method is void?

The result is stored in urlText.Text, so there is no need to return a value. I think this is just a wording mistake...

No need to use readLineAnync() when you've already put await before the statement you can use readLine()

I think we should use ReadToEndAsync instead of ReadLineAsync. Right?

The req says "The GetData() method must return a string value that contains the first line of the response from the web service.". You need first line only hence ReadLineAsync is used
