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•4mo 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

Akama Aka @ DoKomi•4mo ago

No description

Akama Aka @ DoKomi•4mo 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•4mo ago

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

Akama Aka @ DoKomi•4mo ago

Yes

reflectronic•4mo ago

you did not call AddWindowsService

Akama Aka @ DoKomi•4mo 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•4mo ago

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

Akama Aka @ DoKomi•4mo ago

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

reflectronic•4mo ago

no, that does not matter

Akama Aka @ DoKomi•4mo ago

Hm

Akama Aka @ DoKomi•4mo 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

Akama Aka @ DoKomi•4mo ago

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

reflectronic•4mo ago

is there anything in the event logs related to the application

Akama Aka @ DoKomi•4mo ago

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

reflectronic•4mo ago

what was the missing dll and how did you fix it

Akama Aka @ DoKomi•4mo ago

Just added the .dll file into the folder

reflectronic•4mo ago

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

Sir Rufo•4mo 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() );

Akama Aka @ DoKomi•4mo ago

C:\Users<Name>\Desktop\servs

Sir Rufo•4mo ago

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

reflectronic•4mo ago

you pointed it at the exe file?

Akama Aka @ DoKomi•4mo 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•4mo 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

Akama Aka @ DoKomi•4mo ago

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

reflectronic•4mo ago

it is not a container

Akama Aka @ DoKomi•4mo ago

oh

reflectronic•4mo 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

Akama Aka @ DoKomi•4mo ago

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

reflectronic•4mo ago

i mean if you are doing dotnet publish

Akama Aka @ DoKomi•4mo ago

-p:PublishSingleFile=true

reflectronic•4mo ago

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

Akama Aka @ DoKomi•4mo ago

What is SelfContained doing?

MODiX•4mo ago

reflectronic

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

Akama Aka @ DoKomi•4mo 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•4mo ago

how do you know it is not running it

Akama Aka @ DoKomi•4mo 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•4mo ago

before you changed what

Akama Aka @ DoKomi•4mo 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•4mo 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

Akama Aka @ DoKomi•4mo ago

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

reflectronic•4mo ago

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

Akama Aka @ DoKomi•4mo ago

It does nothing in generall It just starts not more

reflectronic•4mo ago

what do you mean by "in general"

Akama Aka @ DoKomi•4mo ago

Sec I'll dm you the redacted things

reflectronic•4mo 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

Akama Aka @ DoKomi•4mo 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•4mo ago

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

Akama Aka @ DoKomi•4mo ago

Yes

reflectronic•4mo ago

it looks like your service uses some UI features

Akama Aka @ DoKomi•4mo ago

Do you mean the Console logs?

reflectronic•4mo ago

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

Akama Aka @ DoKomi•4mo ago

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

reflectronic•4mo ago

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

Akama Aka @ DoKomi•4mo ago

Hm sec Then shouldn't jt lognerrors?

reflectronic•4mo ago

you just need to check the check box i think

No description

reflectronic•4mo ago

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

Akama Aka @ DoKomi•4mo ago

Yes but still not working :/

reflectronic•4mo ago

do you see message boxes now

Akama Aka @ DoKomi•4mo ago

Possible Nope nothing

reflectronic•4mo ago

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

Akama Aka @ DoKomi•4mo ago

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

Sir Rufo•4mo ago

Come on, interactive services are obsolete since years

Sir Rufo•4mo 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).

Akama Aka @ DoKomi•4mo ago

The only thing it should do is lock the user

Sir Rufo•4mo ago

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

Akama Aka @ DoKomi•4mo ago

Yes

Sir Rufo•4mo 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

Akama Aka @ DoKomi•4mo ago

Yes

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

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?
