Task and Async

Hello Ben,

I have updated your code and tested, it works:

        private async Task GetLocalIp()
        {
            int timeout = 5000;
            var cts = new CancellationTokenSource(timeout);
            var result = string.Empty;

            var timeoutTask = Task.Run(async () =>
            {
                await Task.Delay(timeout);
                result = "Error:Timed Out. A connection could not be found.";
            }, cts.Token);

            var scheduledTask = Task.Run( () =>
            {
                try
                {
                    var icp = NetworkInformation.GetInternetConnectionProfile();

                    if (icp?.NetworkAdapter != null)
                    {
                        var hostname = NetworkInformation.GetHostNames().SingleOrDefault(hn => hn.IPInformation?.NetworkAdapter != null && hn.IPInformation.NetworkAdapter.NetworkAdapterId == icp.NetworkAdapter.NetworkAdapterId);

                        result = hostname?.CanonicalName;
                    }
                }
                catch(Exception ex)
                {
                    result = $"Error:{ex.Message}";
                }

            }, cts.Token);

            await Task.WhenAny(scheduledTask, timeoutTask);
            cts.Cancel();

            await Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal,
            () =>
            {
                IPAdressTextBlock.Text = result;
            });
        }

Even though I don't think this would cause deadlock, you can refer to this blog ant msdn article to understand Deadlocks, it is a better option to use a dynamic variable.

Best Regards,

Michael
