C# Service: Error 1053: The service did not respond to the start or control request in a timely fashion

Hello,

I have a problem with a self programmed windows service for .Net 6 that inherits from BackgroundService:

namespace WooComMesserschmidt
{
internal class Worker : BackgroundService
{
private readonly HttpClient Client = new()
private string BaseAddress = string.Empty;
private readonly IConfiguration Configuration;
private string ConfigFile = string.Empty;
private readonly Dictionary _ConfigPar;
internal static Dictionary ConfigPar = new();
private readonly ILogger _logger;

	public struct LogInfo
	{
		public ILogger? Logger;
		public string?			LogFile;

		public LogInfo(ILogger? logger, string logfile)
		{
			Logger	= logger;
			LogFile	= logfile;
		}
	}

	public static LogInfo logInfo;

	public Worker(ILogger logger, IConfiguration configuration, Dictionary configpar)
	{
		Configuration	= configuration;
		\_ConfigPar      = configpar;
		\_logger         = logger;

		Init();
	}

...

In the method "Init()" relatively extensive tasks take place (on my PC it takes about 2 seconds). If these are through, it goes on here:

protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
if (int.TryParse(ConfigPar[cpQueryInterval], out int QueryInterval) == false)
{
QueryInterval = QueryIntervalStd;
Log.LogInformation(logInfo, $"Abfrageintervall konnte nicht ermittelt werden. Es wird daher der Standardwert von {QueryInterval} Millisekunden verwendet. Prüfen Sie die Angaben in der Parameterdatei.");
}

		Log.LogInformation(logInfo, $"{Process.GetCurrentProcess().ProcessName} gestartet.");
		Log.LogInformation(logInfo, $"Worker arbeitet mit Abfrageintervall von {QueryInterval} Millisekunden.");

		while (stoppingToken.IsCancellationRequested == false)
		{
			await ProcessNewOrders();

			await UpdateProducts();

			Dhl\_Polling();

			await Task.Delay(QueryInterval, stoppingToken);
		}
	}

...

The service is supposed to fetch orders from an eShop every few minutes, update items and process DHL shipments.

Well, when I start the program manually in the command line (i.e. not as a service), everything works as expected. Now I have registered the program as a service and every time I try to start the service I get the following error:

That would suggest that your startup code is taking too long. You mention the Init method contains "extensive tasks" - I'd suggest moving some or all of those to the start of the ExecuteAsync method instead.

Thank you. That's exactly what I did yesterday, but the error remained. I will try again, but now rested ;-)

OK, problem solved. The error message had driven me astray and I was looking in the wrong place for the cause of the error. Now I proceeded systematically step by step: at the very beginning, the service crashes without doing anything. The error was due to the "displayname" of the service - this may be maximum 80 characters long, while I used 110 characters. I didn't know that and the error message also said something completely different. Thanks for your help! The weekend is saved! René
