问题 I have notifications going to my application, I want to be able to take the user to that page in my application when they click on the notification or live tile (current displayed item).

Is there a way to detect that so I can turn off sending them live tiles or does WNS handle that? Thanks! 回答1: Windows

问题 I am trying to use Async and Await when making a web request and am finding that it never gets past the await line. I am doing this from a Metro app, but I also verified the problem in a winforms app. public async Task<string> DoSomething() { string url = "http://imgur.com/gallery/VcBfl.json"; HttpWebRequest request = HttpWebRequest.CreateHttp(url); var ws = await request.GetResponseAsync(); return ws.ResponseUri.ToString(); ; } If I don't use await and instead perform a synchronous wait, it
