Also, when I paste the code, it appears to have spaces missing, so I have been through the code and added missing spaces and editing it to the best of my knowledge. I have added the XAML code to the <Application.Resources> of the App.xaml

问题 Does anyone try using Udp Unicast on Windows Phone 7.1 (RC)? I have a few questions that I like to ask you guys. According to the document http://msdn.microsoft.com/en-us/library/system.net.sockets.socket(v=VS.95).aspx, the only supported ProtocolType is the TCP protocol.

问题 I would like my sales staff to click a button, which makes a phonecall and registers the length of the call. Is it possible to monitor the length of a phonecall? Thanks 回答1: No, the PhoneCallTask does not provide this kind of information. But you could register the current time just before the call starts and get the current time when the app resumes. However, this might be longer than the actual phone call when the user or phone decides to do something else in between. EDIT Apparently, after

问题 WaitHandle.WaitAll throws a NotSupportedException when executed on Windows Phone (7.1). Is there an alternative to this method? Here's my scenario: I am firing off a bunch of http web requests and I want to wait for all of them to return before I can continue.
