Task and Async

Hello glowblujel,

I think you can create an anonymous task for this issue like following code.

public MainPage()
        {
            this.InitializeComponent();

            GetLocalIp().ConfigureAwait(false);
        }

        private async Task GetLocalIp()
        {
            int timeout = 1000;
            var task = Task.Run( async () =>
            {
                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);

                        await Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal,
                        () =>
                        {
                            IPAdressTextBlock.Text = hostname?.CanonicalName;
                        });
                    }
                }
                catch
                {
                    await Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal,
                    () =>
                    {
                        IPAdressTextBlock.Text = "Network not found.";
                    });
                }
            });

            await Task.WhenAny(task, Task.Delay(timeout));
        }

You can also refer to this topic. Hope that is helpful for you.

In addition, please note that, Code running on a background thread/Task cannot manipulate UI elements directly without raising a cross-thread exception. Instead, you must run UI code using a dispatcher. This task snippet encapsulates the typical dispatcher usage in Universal Windows Platform (UWP) apps.

Best Regards,
