FYI - Deleting the service and files is not necessary to update the executable. You can just stop the service, publish your changes, and then start the service up again. Aside from that this is an EXCELLENT tutorial!
@@IAmTimCorey That is a valid point although perhaps only really necessary once you're ready to deploy to production. During development and testing it seems a bit excessive, and I've had cases where deleting a service failed and the only resolution was to reboot. I guess I'm just a bit more gun shy about creating/deleting services more than absolutely necessary.
Tim, I've recently started work on a Windows Service project and I've been looking all over for examples on how to do it. By far, this has been the clearest example that I've seen. Thanks, Scott
Great video. Of note, if you are simply updating the service, you can stop the service, copy/replace the files and start the service. No need to uninstall.
Absolutely amazing video, I started my internship as C# developer today, the project that I'm working with have a lot of worker services this video is very useful.
THANK YOU! I watched your other video on services ~1 year ago and thought "that's interesting, but I don't think I'll use that"...At work I was just asked to write a simple monitoring tool for our other services and this came in immensely handy.

Who knew? It just happens I am converting a console app / service that I wrote years ago from .NET Framework to .NET Core. I did the service bare metal using InstallUtil. That's fine, but It appears that this will accomplish the same thing in COre, and give me a Linux Daemon on top of it, with much simpler code. I am just lucky to have stumbled across this !!
great video Tim, also great content on your website. Keep up the good work. I hope people can make the difference between quality content like yours and other "made on the knees" content who just floods youtube and other chanels.

Tim, it was very nice. Thank you. Please, send more videos about Worker Services, but now, working the advanced ways. Example: "Worker Services with Selenium automation"
Thank you, Tim. This is a very informative video. I watched it because I have a service that needs to run but I'm choosing to run it as a console app under the Windows Task Scheduler. I still wanted to explore my options though.
I used to use the console app as a Windows task scheduler but I've noticed that it pop up the command prompt everytime it run. Have u found a way to disable this?
When using classic WindowsServices for example, you just have to stop the service, recompile the service project with your changes and start the service again. You don't need to delete the deployment files or the delete the service. Just restart the service after recompile. Can we still use OnStop OnShutdown OnPowerEvent from ServiceBase? Very nice intro to Worker Services!
What do you mean "add the installer"? You can run the command I showed on screen for installing the service on any machine. What are you looking for beyond that?
@@AllenMichaelsVlogs In the past, I was able to generate an MSI (Microsoft Installer) that would deploy the bits and set up services using Flexera Installshield. It might not work for the project type demonstrated here as their website doesn't list support for .net Core 3 yet but I suppose it's only a matter of time. Give that a look - it was very simple to set up the package once compiled.

Very useful. Please keep up the good work. Only thing I noticed that you could use string interpolation to make code more readable. instead of saying Log.info("Web Site Status: {statusCode}", statusCode); could do : Log.info($"Website Status: {statusCode} "); notice the '$'
Actually, there is a difference. I pointed it out briefly. If you do it my way, a structured logger like Serilog can pull out that data and store it separately so that you can query on it later in the logs (where statusCode = 401 or temperature > 50 would be examples). If you use string interpolation, you only get a string stored in your log statement so you would need to do a regex match to try to pull out the values.
I haven't made a service in .NET Core yet. But have a Template application that for .NET 2.5 or above. It uses the regular "Windows Services" project type. It can run in debug and display stuff on the console. But once installed as a service it will just run as normal. Also I can just run the exe and put "MyService --install" to put it in services... or "MyService --uninstall" to delete if from services... No third party software involved. I even ported it over to VB for a project I was working on for a company that was all VB.
Thanks for your video. It's so in depth. Are you able to do a video on automating the deployment of a windows service? Eg Deploying from some generic CI/CD pipeline on some server and deploying the service to another server that may or may not have the service already running?
Instead of using this method of installing a service one can also use nssm. It supports better failure and recovery scenario's as well as logging console output. This way you can easily create a worker that is suitable as a pod in Kubernetes as well as a Windows service without needing serilog. Another thing: When you return from ExecuteAsync for whatever reason the service will not stop. If you want to stop the service from within the ExecuteAsync when an error occurs or something like that: Call StopApplication on IApplicationLifetime. Just add IApplicationLifetime as a parameter to the constructor of your worker and use that.
Windows services has the benifits of not needing extra software installed and has basic recovery. Also, having a service stop itself sounds like an anti-service? I would either have a service continue running in idle mode untill needed again or set up a scheduled task.
I want to warn people that if they use this 'BackgroundService' and the service enters a critical state - disk full, other network services not available, data corruption, disk read error, etc... - that IF you wanted to stop the service that you have to do more than return from ExecuteAsync. Without calling StopApplication your service will remain idle forever, but it keeps the service running - probably to cover the scenario of running multiple 'BackgroundServices'. Why would you want a service to stop itself in such a case? To take advantage of monitoring, alerting, fail-over mechanisme provided by Windows or Kubernetes, etc... Surely you don't have to use nssm. I used it to make .NET Core Worker work on Windows because we are working towards more and more deployments on a Kubernetes cluster, but not everything can run on it right now and for these new parts in legacy systems this could provide a solution. This prevents me overcomplicating the application with legacy features like logging to a file.
If you are using a newer version of asp net core, your useSerilog and useWindowsService will look more like this: builder.Services.AddWindowsService(options => options.ServiceName = "Sample Service"); builder.Services.AddSerilog(); //Very important to place them BEFORE var host = builder.Build();
You can actually use hangfire inside of a service. Hangfire is more about scheduling where services are about running something continually in the background.
5:00 To be clear, there is no GUI... At least not directly. It may host a web server, for instance, but that's about it. It should, I think, generate some logging, maybe output to the Windows Event Viewer, which most service oriented admins ought to be familiar with for a long while now.
My thought was that you could also do a using statement wrapped around the while loop (just for this simple case, other cases cleaning up in stop method is correct)
Hi tim. May I know where'd the video that you made for console application that runs in background process? Really need helo about that. Love your tutorials tim
@@IAmTimCorey Wow! so quick response.. I really not expected this fast. Hats off to you Tim, our devs community must be loving you a lot. Love from India too 😘
Great video! Completely understood. The outstanding question I've got, though, is how or where do I pass a Cancellation token to end my service operation?
Hi Tim great video you mention the possibility to trigger the service based on an event in a database could you elaborate on that. Is that done on the DB side using events or sound really interesting. Love you r videos i get so much inspiration from this keep it up!
A worker service can monitor the database for changes by just calling a small query on a schedule. If something has changed, it can get the new data and do something. For example, if you had a People table, you could do a "select max(id) from People", which would return the last identifier issued. Let's say the first time it is called, you get back id number 10. If you run it again and you get back id number 12, you know that you have at least one new record. You can run "select * from People where id > 10" to get the new records.
I'm planning on creating a worker service for our batch processing jobs that uses Quartz clustered scheduler. I can't use this yet, since we're waiting for .NET Core 3.1 (LTS), but I've started by using the GenericHost and Topshelf.
Thanks for this awesome video, Tim! Q: In your opinion, what would be the best project type for a task that needs to be executed through a scheduled task (Windows)? Let's say that this task needs to run daily... It seems that a Worker Service is more appropriate for monitor applications.
If you are going to schedule an app to run through the task scheduler, create a Console app. Just make sure that it does not have a ReadLine() at the end to stop it from closing.
how to send 'work / task / a call to code inside the service with parameters' to be executed by the worker service ? or it is just an infinity loop that would keeping checking on something ? maybe keep checking on a db for instructions to be executed ?

True, but by deleting the files, you ensure you don't leave any scraps behind from the old application. It is a good practice to have.
@@IAmTimCorey That is a valid point although perhaps only really necessary once you're ready to deploy to production. During development and testing it seems a bit excessive, and I've had cases where deleting a service failed and the only resolution was to reboot.

A worker service can monitor the database for changes by just calling a small query on a schedule. If something has changed, it can get the new data and do something. For example, if you had a People table, you could do a "select max(id) from People", which would return the last identifier issued. Let's say the first time it is called, you get back id number 10. If you run it again and you get back id number 12, you know that you have at least one new record. You can run "select * from People where id > 10" to get the new records.
good job and good luck bro!!!
Thanks very much Tim for your great work.
You are the best
Thank you!
I'm planning on creating a worker service for our batch processing jobs that uses Quartz clustered scheduler. I can't use this yet, since we're waiting for .NET Core 3.1 (LTS), but I've started by using the GenericHost and Topshelf.
Great!
Well delivered, and many thanks!

Q: In your opinion, what would be the best project type for a task that needs to be executed through a scheduled task (Windows)? Let's say that this task needs to run daily... It seems that a Worker Service is more appropriate for monitor applications.
If you are going to schedule an app to run through the task scheduler, create a Console app. Just make sure that it does not have a ReadLine() at the end to stop it from closing.
Thank you very much@@IAmTimCorey!
This is fabulous. Thank you Tim
You are welcome.
how to send 'work / task / a call to code inside the service with parameters' to be executed by the worker service ?
or it is just an infinity loop that would keeping checking on something ?
maybe keep checking on a db for instructions to be executed ?
Oh, the last few seconds of the video answered my question :)
Love it. Thanks!
You are welcome.
