Remarks
This operation will not throw an exception on network errors. Instead you should examine the HttpRequestResult to learn about the original HTTP request, the resulting HTTP response (if any) and error (if any). This operation will throw when the operation is canceled.
This operation will not block. The returned IAsyncOperationWithProgress (of HttpRequestResult and HttpProgress) completes after the whole response (including content) is read.

This operation will not block. The returned IAsyncOperationWithProgress (of HttpRequestResult and HttpProgress) completes based on the completionOption parameter after part or all of the response (including content) is read.
