Handling CancelKeyPress using a CancellationToken https://www.meziantou.net/detecting-console-closing-in-dotnet.htm

const int WaitIndefinitely = -1;
using var cts = new CancellationTokenSource();
Console.CancelKeyPress += (sender, e) =>
{

    // Change the state of the CancellationToken to "Canceled"
    // - Set the IsCancellationRequested property to true
    // - Call the registered callbacks
    cts.Cancel();
};


try
{
    // code using the cancellation token
    Console.WriteLine("Waiting");
    await Task.Delay(WaitIndefinitely, cts.Token);
}
catch (OperationCanceledException)
{
    Console.WriteLine("Operation canceled");
}

Console.WriteLine("Closing application...");
