Windows phone 7 how to get Synchronous http response

Answer 1

You should never make synchronous network calls, it will freeze up your UI (and therefore your phone) which is a very bad user experience.

Instead do it asynchronously, something like:

wp.pubTimeLine(url, result => textBlock1.DataContext = result);

Where the second parameter is a lambda expression containing the callback that is called when the pubTimeLine method is done executing asynchronously.
