This is the pattern we use in IA C# 2.8.1:
static async Task<int> Main(string[] args)
{
try
{
Console.WriteLine($"Service starting at {DateTime.Now}");
var cancelTokenSource = new CancellationTokenSource();
AppDomain.CurrentDomain.ProcessExit += (s, e) =>
{
Console.WriteLine("Exiting");
cancelTokenSource.Cancel();
};
await Task.Delay(-1, cancelTokenSource.Token);
return 0;
}
catch (TaskCanceledException)
{
// Don't care as this is thrown by Task.Delay()
Console.WriteLine("Process exit via TaskCanceledException
(SIGTERM)");
return 0;
}
catch (Exception e)
{
Console.WriteLine($"Unhandled exception: {e}");
Console.WriteLine($"Stack trace: {e.StackTrace}");
return -1;
}
}
