Windows Worker Service times out

Hello. Everytime I want to start my Worker Service I get the message that it doesnt reacted in time and I dont know why I get this error. because everytime I run the exe noremally the whole thing works. Program.cs

using My_Service;

HostApplicationBuilder builder = Host.CreateApplicationBuilder(args);
builder.Services.AddHostedService<Worker>();
IHost host = builder.Build();
await host.RunAsync();

using My_Service;

HostApplicationBuilder builder = Host.CreateApplicationBuilder(args);
builder.Services.AddHostedService<Worker>();
IHost host = builder.Build();
await host.RunAsync();

Worker.cs

using System.Net.Mime;

namespace My_Service;


public class Worker : BackgroundService
{
    private readonly ILogger<Worker> _logger;

    public Worker(ILogger<Worker> logger)
    {
        _logger = logger;
    }
    
    
    
    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        
        while (!stoppingToken.IsCancellationRequested)
        {
            _logger.LogInformation("My Service running at: {time}", DateTimeOffset.Now);
            try
            {
                myServiceCode.systemcode();
                _logger.LogInformation("Started Service Service Code");
                //await Task.Delay(1_000, stoppingToken);
            }
            catch (Exception e)
            {
                _logger.LogError("Error in Service Code: {e}", e);
            }
            await Task.Delay(60000, stoppingToken);
        }
    }
}

using System.Net.Mime;

namespace My_Service;


public class Worker : BackgroundService
{
    private readonly ILogger<Worker> _logger;

    public Worker(ILogger<Worker> logger)
    {
        _logger = logger;
    }
    
    
    
    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        
        while (!stoppingToken.IsCancellationRequested)
        {
            _logger.LogInformation("My Service running at: {time}", DateTimeOffset.Now);
            try
            {
                myServiceCode.systemcode();
                _logger.LogInformation("Started Service Service Code");
                //await Task.Delay(1_000, stoppingToken);
            }
            catch (Exception e)
            {
                _logger.LogError("Error in Service Code: {e}", e);
            }
            await Task.Delay(60000, stoppingToken);
        }
    }
}

what is the error that you are getting, exactly

Sir Rufo•2y ago

Your ExecuteAsync runs sync until the first await Task.Delay. I guess serviceCode.systemcode() does some lengthy operation and because it is run sync you get that message

Kasumi (Deactivated Account)OP•2y ago

Yes it's doing an infinite loop with a check So I just have to switch the logger message with the myservercode... Right?

reflectronic•2y ago

oh, you want to run it as a Windows Service?

Kasumi (Deactivated Account)OP•2y ago

Yes

reflectronic•2y ago

you did not call AddWindowsService

Kasumi (Deactivated Account)OP•2y ago

Oh hm But I've the same thing with Sec I've that:

//System.Diagnostics.Debugger.Launch();
/*
IHost host = Host.CreateDefaultBuilder(args)
    .UseWindowsService(options =>
    {
        options.ServiceName = "my Service";

    })
    .ConfigureServices(services =>
    {
        services.AddHostedService<Worker>0();
    })
    .Build();

await host.RunAsync();

//System.Diagnostics.Debugger.Launch();
/*
IHost host = Host.CreateDefaultBuilder(args)
    .UseWindowsService(options =>
    {
        options.ServiceName = "my Service";

    })
    .ConfigureServices(services =>
    {
        services.AddHostedService<Worker>0();
    })
    .Build();

await host.RunAsync();

And it's also not working

reflectronic•2y ago

well, i can guarantee that it will not work without UseWindowsService

Kasumi (Deactivated Account)OP•2y ago

Okay And if I do that it should work then right?

reflectronic•2y ago

no, that does not matter

Kasumi (Deactivated Account)OP•2y ago

Hm

Kasumi (Deactivated Account)OP•2y ago

Ms isn't doing it differently https://learn.microsoft.com/en-us/dotnet/core/extensions/workers

HostApplicationBuilder builder = Host.CreateApplicationBuilder(args);
builder.Services.AddWindowsService(options => options.ServiceName = "My Worker");
builder.Services.AddHostedService<Worker>();
IHost host = builder.Build();
await host.RunAsync();

HostApplicationBuilder builder = Host.CreateApplicationBuilder(args);
builder.Services.AddWindowsService(options => options.ServiceName = "My Worker");
builder.Services.AddHostedService<Worker>();
IHost host = builder.Build();
await host.RunAsync();

this should just work

Kasumi (Deactivated Account)OP•2y ago

Okay i'll try as soon as I'm in work Doesn't work

reflectronic•2y ago

is there anything in the event logs related to the application

Kasumi (Deactivated Account)OP•2y ago

Oh missing .dll file But now "Could not resolve CoreCLR path."

reflectronic•2y ago

what was the missing dll and how did you fix it

Kasumi (Deactivated Account)OP•2y ago

Just added the .dll file into the folder

reflectronic•2y ago

how did you configure the service like, what is the path it's trying to run

Sir Rufo•2y ago

No. You block the ExecuteAsync method with the serviceCode.systemcode() and that causes the not responding service. As a rough method change it to await Task.Run( () => serviceCode.systemcode() );

Kasumi (Deactivated Account)OP•2y ago

C:\Users<Name>\Desktop\servs

Sir Rufo•2y ago

But you should be aware that you cannot stop that task, because you did not code that method to be stopable

reflectronic•2y ago

you pointed it at the exe file?

Kasumi (Deactivated Account)OP•2y ago

Like that?

try
            {
                _logger.LogInformation("Started My Service Code");
                await Task.Run(() =>
                {
                    [redacted].[redacted]();
                });
                await Task.Delay(1_000, stoppingToken);
            }

try
            {
                _logger.LogInformation("Started My Service Code");
                await Task.Run(() =>
                {
                    [redacted].[redacted]();
                });
                await Task.Delay(1_000, stoppingToken);
            }

yes :thonkThinkWatWutWhatDerpConfused: then I need to look how I can stop it then

reflectronic•2y ago

well, the "Could not resolve CoreCLR path." means it is not even running right now i think the easiest way to fix it is to use self-contained

Kasumi (Deactivated Account)OP•2y ago

running in a container will make the whole program useless Because it checks for a USB Device

reflectronic•2y ago

it is not a container

Kasumi (Deactivated Account)OP•2y ago

oh

reflectronic•2y ago

it just means that it puts the .NET runtime next to the exe so it does not have to look for your installation which, for whatever reason, it can't do <SelfContained>true</SelfContained> in your project file in the PropertyGroup then when you build you have to copy the entire build folder to wherever the service is running from do not just copy a handful of files, you cannot forget anything or the whole thing doesn't work

Kasumi (Deactivated Account)OP•2y ago

And I cant build it with -p:PublishReadyToRun=true into a single .exe

reflectronic•2y ago

i mean if you are doing dotnet publish

Kasumi (Deactivated Account)OP•2y ago

-p:PublishSingleFile=true

reflectronic•2y ago

then instead of the <SelfContained> business i would do dotnet publish -p:PublishSelfContained=true -p:PublishSingleFile=true ... yeah that is fine

Kasumi (Deactivated Account)OP•2y ago

What is SelfContained doing?

MODiX•2y ago

reflectronic

it just means that it puts the .NET runtime next to the exe

Kasumi (Deactivated Account)OP•2y ago

Ah Now it's started But it does nothing :shyyDead:. But prob. I need to download the driver for the usb device sec @reflectronic but now it doesn't run the redacted code

reflectronic•2y ago

how do you know it is not running it

Kasumi (Deactivated Account)OP•2y ago

The [redacted].redacted; Because it does nothing Before I changed all of that, it worked But now if I unplug the usb device it does nothing

reflectronic•2y ago

before you changed what

Kasumi (Deactivated Account)OP•2y ago

All what we discussed here If I run the .exe normally in the console it doesn't log that what it should as soon as the [redacted].redacted; is called

reflectronic•2y ago

yes, you can't just run a windows service as a console application if you want to run it as a console application you need to delete AddWindowsService and rebuild it

Kasumi (Deactivated Account)OP•2y ago

Ik but it doesn't even call the one class Can I DM you the top of the code?

reflectronic•2y ago

i mean. yes, if you do AddWindowsService, and then run it as a console application, it will do nothing this is expected

Kasumi (Deactivated Account)OP•2y ago

It does nothing in generall It just starts not more

reflectronic•2y ago

what do you mean by "in general"

Kasumi (Deactivated Account)OP•2y ago

Sec I'll dm you the redacted things

reflectronic•2y ago

i still don't understand what is different now if you delete AddWindowsService, and run it as a console application, it will work exactly as it did before it does not matter what the code is doing

Kasumi (Deactivated Account)OP•2y ago

Yes it also would do the things it should do. But as soon as I run it as Service it doesn't work

reflectronic•2y ago

the fact that it isn't working as a windows service is a different matter

Kasumi (Deactivated Account)OP•2y ago

Yes

reflectronic•2y ago

it looks like your service uses some UI features

Kasumi (Deactivated Account)OP•2y ago

Do you mean the Console logs?

reflectronic•2y ago

i mean, there is MessageBox this means it needs to run as an interactive service

Kasumi (Deactivated Account)OP•2y ago

Oh yea but that's not so important The most important thing is to get the base working :gx_laugh:

reflectronic•2y ago

the fact that you are not running it as an interactive service may be the reason it is not working

Kasumi (Deactivated Account)OP•2y ago

Hm sec Then shouldn't jt lognerrors?

reflectronic•2y ago

you just need to check the check box i think

No description

reflectronic•2y ago

in the service properties i mean. who knows what it does right now. maybe it just hangs

Kasumi (Deactivated Account)OP•2y ago

Yes but still not working :/

reflectronic•2y ago

do you see message boxes now

Kasumi (Deactivated Account)OP•2y ago

Possible Nope nothing

reflectronic•2y ago

if you put a MessageBox at the very beginning do you see it

Kasumi (Deactivated Account)OP•2y ago

Sec Nothing Could it be that windows can't find the driver from the usb device?

Sir Rufo•2y ago

Come on, interactive services are obsolete since years

Sir Rufo•2y ago

since Vista https://learn.microsoft.com/en-us/windows/win32/services/interactive-services

Interactive Services - Win32 apps

Typically, services are console applications that are designed to run unattended without a graphical user interface (GUI).

Kasumi (Deactivated Account)OP•2y ago

The only thing it should do is lock the user

Sir Rufo•2y ago

It does not matter what it "only" should do - you simply can not have interaction from a service to the desktop. period.

Kasumi (Deactivated Account)OP•2y ago

Yes

Sir Rufo•2y ago

If you want an interaction you need two instances/applications and one has to run in the context of the current user which will communicate with the service and do the interaction with the user

Kasumi (Deactivated Account)OP•2y ago

Yes

Both I tried Why? But could it be that it needs user32.dll?

Kasumi (Deactivated Account)OP•2y ago

Because it needs to interact with user specific things like lock the user and more I'd do in private but not in public

If I share it to someone in private and the person publishes the code without my consent, then I know then who I can sue then Can I send you the files in private?
