我正在尝试使用 WP8 上的 Live SDK 登录。我能够登录几天，但现在没有对代码进行任何更改，我得到了第一次机会异常。

使用的代码：

 try
        {
            auth = new LiveAuthClient("0000000044107D80");
            LiveLoginResult result = await auth.InitializeAsync(new string[] { "wl.basic", "wl.signin", "wl.emails" });
            if (result.Status != LiveConnectSessionStatus.Connected)
            {
                result = await auth.LoginAsync(new string[] { "wl.basic", "wl.signin", "wl.emails" });
            }
            if (result.Status == LiveConnectSessionStatus.Connected)
            {
                var connect = new LiveConnectClient(auth.Session);
                var opResult = await connect.GetAsync("me");
                dynamic nameResult = opResult.Result;
                MessageBox.Show(string.Format("Welcome, {0}", nameResult.first_name));
            }
            }
        catch (Exception ex)
        {
            System.Diagnostics.Debug.WriteLine(ex.StackTrace);
        }

堆栈跟踪：

没有用 try/catch 包围登录部分，我在调试控制台上得到了这个：

A first chance exception of type 'System.Reflection.TargetInvocationException' occurred    in mscorlib.ni.dll
A first chance exception of type 'System.Reflection.TargetInvocationException' occurred in System.Windows.ni.dll

什么可能导致这种行为？
