I don't know if you'll ever read this, I started learning C# about 2 weeks ago. I needed a new hobby for the quarantine and I figured that this one will do. You're honestly one of the most gifted people in passive knowledge I've ever encountered in my life, thank you for all the work you're putting in for us common people to learn. I can only wish you to never stop doing this for as long as you're enjoying this. Thank you very much.
Thanks Tim, this is exactly what I needed. My buddy at work needed something to scan a directory for files, process the file data and generate an xml document for each file. It allows 2 systems to communicate that otherwise couldn’t, saving a project. Scheduled a Teams meeting to get the details of what he needed… 10 mins in I pulled up this video and 45 mins later we had it working! It was my first service too. Your content has made me a lot of money over the years! 150% increase in pay over the last 5 years at a large multinational company, the biggest contributing factor being the ability rapidly to solve little issues like this. It even got me an opportunities to go to Microsoft’s executive briefing center in Redmond. Never would have thought I would have the opportunities 5 years ago. I’ve had the all access pass to your paid content for a few years now and it’s worth every penny. The new Blazor course is great. I turned another buddy at work on to your content and he purchased a course too. Keep up the great work Tim!
I'm a junior c# full stack developer and I have to say Sir , you are a great help, not only make it easy to understand with step by step tutorial and also with a very clear and easy understand explanation. Thank you.
Wow, I'd heard about TopShelf, but never really looked into it, this makes debugging services so much easier - and looks easy to convert existing services to use Topshelf - Thanks Tim!
WOW! I've been avoiding using services for over 10 years cause of the messiness of troubleshooting while developing. Today while watching your video, I learned how to, and proceeded to convert a simple console application to a service. Thanks a million!
Hi, I've been using services a lot, but they allways come with console sibling. My pattern was very simplistic. Entire job was done in class library and service in start/stop methods only called start/stop methods in class library. The same job is doing console application. Debuging was easy, just debug console application. And for fun, sometimes forget to reference some library in service application :)
What an absolutely SUPERB video - so well explained and I wrote a Windows Service in less than 3 minutes after watching this start to finish. Absolutely brilliant. Thank you!
I made a small service to routinely clean up my downloads folder like you suggested. Works great! You are inspiring me to "play with" C# more than I did in the past with all these great tutorials!
Thanks Tim! This couldn't have come at a better time. I just started to write a service on Friday and now I'm going to do it this way. Love your videos; they are so easy to understand.
Tim - thanks - I just finished your c# mastercourse (which was great!) and am embarking on my own projects to build a portfolio. I have a desktop scanner and a printer, and I'm going to create a service that watches the folder for newly scanned pdfs and then prints them - essentially a photocopier. Thanks to your helpful videos, I think I can pull this off.
Many Thanks Tim, I used to apply a do-while-loop to let a program keep running. I heard about the services as a best practice in such a circumstances but it looked a little scary to me. Thanks you again for make it so simple and understandable.
The best lecture ever. I was Wondering on how to sync SQLite database files to the main server and I thought of checking how services work and here you explained it so clearly Thank you
Thanks Tim! Finally I can abandon my holy trio consisting of Windows service for production, console application for debuging and class library handling all the fun. Service and console app were very simplistic. Just start and stop Task provided by class library.
One idea for usage of this service. Our laptops having Lithium Ion batteries which are best preserved when the power charge is between 40% and 80%. It is not a good idea on the battery to charge it fully to 100% nor drain it to 0%. We can create a service to monitor the battery % and give a pop up message to the user when the battery reaches either 40% or 80% notifying the user to switch on/off the power. Note : I did the same to my iPhone using Shortcuts app. Planning to do the same to my laptop using the info from this video.
So I faced a roadblock here. Apparently Windows Services cannot interact with the UI, thereby I cant use a MessageBox.Show code. Moving to an emailer option for now.
You would need to build a desktop application for that instead. You can make it hide in the system tray, but user interaction means you need to be running in the user's session. Services don't do that unless they are logged in as the user (and then only for that user).
@@IAmTimCorey Hello Tim. Your video is amazing! Thank you for that! I just have one question. How did you learn how to make services in C# and how much time did you spend on it in order to learn that?
Thank you Tim. I did watch few different videos on this same topic. But this was simply the best. You explained the concept, the tools and the process so clearly and effectively. The idea of creating a console app instead of using the service project is brilliant. It saves so much time in debugging when we do a complicated service. Thanks mate. Much appreciated. BTW, it would be great if you could do a follow up video on using Squirrel with this project.
I'm pretty sure that you've listened this many times. You rock bro! His video helped to me so much, can you make a video talking about the services recovery options?
Great video, nice introduction to a topic I knew absolutely nothing about. I'd love to see a video on using Github within Microsoft Visual Studio for a simple project. The older one is good but think one using the actual baked-in functionality would be very helpful.
Very helpful. I always have trouble with brown outs in my area and I have a plex server running in my basement. If I am out of town, the server would restart but the plex software would not. I created a service called to launch plex when the server rebooted automatically. Works perfect.
Thank you very much! I am learning C# and i wanted to create a service for deleting a regedit folder if exists, i didn't know the language used on Windows services was c#. So this makes me learn it even more :D
I always wanted to learn how to do that. Excelent way of teaching, could you sometime in the future do a sample of a service watching a DB for example a notification service or anithing using a database
Thanks for another great video tim! I'm using trying to use a service to listen on a socket server from a large number of client connections. The goal is to be able to run a scheduler on these clients and take their payload to store it in a central database.
Awesome! Congratulations! I'm glad I could be a small part in helping you get a job. For the next step to becoming a great C# developer, this might help: www.iamtimcorey.com/blog/20776/become-a-great-csharp-developer
great Video! I always Use Windows Service Project. When I do this, I always create a second project in the same solution with a simple GUI, to trigger the same methods as the service does, when I need to debug it. That also works pretty well, but maybe I will try this solution in the future.
@@IAmTimCorey Hi Tim, I could suggest an idea to create a video showing how a service can get the permissions in order to launch applications as this was my initial goal. It appeared the OS sessions doesn't allow that by default but I read it is achievable.
Hello, I love your tutorials I want to thank you for those! It was very interesting! So I can build my own Windows Service project or install the service automatically. Thank you for explaining what everything does.
Well, that Windows Service project type isn't that hard to debug. I usually do this by attaching the debugger to the process. But Topshelf is definitely better. I do really appreciate your effort for doing those videos. Thanks! :)
Good tutorial. Could you please show how to check and run service when you start some main program e.g. in wpf and stop service if the program is turn off. Thank you.
Hi Tim, Great video on Creating Windows Service in C#. One point, how to create one WITHOUT using "Topshelf"? This is restriction for me as I have to work in client's environment and can't add this toollibrary "Topshelf". Thank you very much for detailed process.
Be good to see a video that expands on this one to show a simple toolbar icon that allows you to start\stop services and maybe open a window that allows one to change a setting.
9:30 OnTimerElapsed ? :D 25:30 Interesting, the Datetime format isn't the same than on executing it within VS. Cool video! Really interesting, especially with that Topshelf package, really easy.
Thanks for the video.. but can I ask, how to brows a file in a service... I'm a student and working on project... I have to create a windows service to load data from csv to SQL server... I have already done the part need to enter data to SQL server... but I couldn't make the part where user have brows the file needed. Thank you.
A service doesn’t have a user interface, so the user cannot browse for a file. However, if you mean that the service looks for a file on its own, that can be done. I have a video on text files on this channel that should show you the code.
Great tutorial, it would be interesting make video about using Hangfire with it's dashboard and Topshelf, for example to send e-mails with attachment from some folder.
I literally just wrote a service like this a month or so ago for a coworker to monitor a pickup directory that a mainframe deposits batches of Resumes for our HR department in a Zip file. When it sees a new file dropped in, it uncompresses the file into a specified directory structure, logs it's activity and then archives the ZIP for a couple days before delating the processed files. I used the VS WinService template to build it, but just wanted to comment to let everyone know there are a lot of occasions where simple services like this are required. As Tim said, be careful though, if you have an unhandled exception in a service the Windows Service manager just quietly kills the process and logs it to the System log. Also to keep in mind that it can be quite tricky to catch all exceptions in a service due to the way the Windows Service manager and .NET services interact (basically .NET registers the Service base class as the exception handler of last resort, even if you try to replace it). All things considered, Windows Services are not difficult to write, but just remember to be extra careful to look for and handle any potential exceptions, however unlikely you think they are. As a final example, the service I wrote ended up receiving a corrupted ZIP file one day, and as it turns out, I didn't account for one exception type the Zip handler could throw in the case of a corrupted file and the service would die almost instantly after starting because of that. These things are easy to miss :)
OnException is not an exception handler. It just allows you to log the exception or do other things to it. You need to still catch the exception properly.
great! So much simpler than BackgroundService hosting. I wonder why they use Environment.ExitCode vs static int Main(string[] args) ... return (int)exitCode;

Hi I've a question, you can run ANY program (.exe) as service as long as you execute "serviceName.exe install start" in the command prompt? or what are the requirements for this command to accept a .exe file as service
No, a service needs to operate without need to interact with the user interface, it should run continually, and it should have methods to properly start and stop it that are based upon the common interface so that the system can properly tell it what to do.
Hi Tim, I new to C# but worked on Console Application in my previous application. This video helps me to know the basics but here is my problem statements: 1. I have an external application running on python, And this python will call our service with two parameters for eg., 1) json object which holds some infos and 2) path as string indicating the location of trace file (path needed to process in our window service). He will use REST API to call one of the function in our service. 2. The main role of our service is to process the trace file that we receive but here the processing is very slow as compared to calling of our service from the python app. I was thinking of creating a Job Queue (need to implement in C#, part of service) which will dump these data as the python calls the service and later the we can read it one by one from the job queue. Is there any video that you can explain the creation of service as API host which can be called from outside. Note: I already created an Console app which process a file which is defined in a local path.
Great Explanation i really appreciate your time in explaining .. :) I have two questions 1) How can we dependency to the service or how can we start dependency service before new Service. 2)Is there any way,on change in database table data can call the windows service which takes the data changes and process accordingly in Windows service
The service can start other items when it starts. As for having the database trigger a service, you would actually do it the opposite way. The service would listen for changes to the database and then trigger an action.
I want to create a service that send statement every 20minutes... And Also reset a particular counter after 24hrs.., Can I have two Timers on the service one for the 20min and the other for the 24hrs. Thank you.
You can but I would recommend using one timer and doing a check to see if 24 hours has passed. So it would fire the 20 minute event each time (if the timer executed every 20 minutes) and it would identify if it needed to fire the 24 hour event or not. You could make the timer fire every minute and then do lots of different timings.
Again, one of the best video i cud get to understand how i can create a win service. Thank you so much. Just want to knw if there's any other way (in built .NET way) to create/install the service without Topshelf?
Hey tim thanks for this video. Please create video on window application auto updater.. Your last video was good but we want some more examples. Hopefully installshield.
@@IAmTimCorey Yes tim. there are very fewer and confusing examples of windows application package updation. It could be self updation or intentionally updation of installed windows application. Whatever it would be from your side is always welcomed. We love u tim. A heroic trainer you are.. 😉
Tim, another great video. I have used Task Scheduler for some similar programs that could just as well be services. Is there any advantage of one over the other?
It is a similar idea but there are a couple benefits of a service. First, they are exposed to the user more readily. Services and their status are listed in the task manager and in the Services portion of the control panel. Also, the user has access to easily choose if a service runs, when it runs, who's permissions it runs under, and more. That gives the user more control over their own system. Finally, a service can keep information between calls more easily. It could have a running counter, a list of things it has done, or anything else that might be useful across calls.
It doesn't matter if you reboot or not. The service will run under the default account unless you specify an account for it to log in as. The service does not run under your account ever (unless you specifically go in and tell the service to do so (and give it your username and password).
Great video! One question: How would you solve the problem when the service actually runs for longer than the timer we set up and it causes problems. Basically what I am looking for is to run the service only 1 minute after the previous process has been finished. I.e. I do not want to have the same service running and processing my data twice at the same time.
Set Timer AutoReset to false, and call _timer.Start() at the end of TimeElapsed function. That way the Timer will never be running 2 processes or more because of the autoreset spawning new processes without the previous one finishing.
Thank you Tim, I'm new to C# but have written a ton of VBScript over the years - mostly with SQL server stuff. I have a project where I inherited a c# console app that translates HL-7 to and from ASTM messages between a lab instruments. The HL-7 is then passed to Mirth Connect which in turn interfaces with a SQL Server based LIS system. I have heavily modified this c# app to communicate directly with SQL server and skip all the HL-7 and Mirth (JavaScript) code. My end goal is to convert this app into a service. One of the biggest hurdles I have yet to master is attempting to get much of the code into classes and out of program.cs. Would this be an issue when converting the app into a service? One of the next steps is to fix the logging. I saw the tutorial you created on Log4Net and thank you for that! At the 5:30 mark where you are installing TopShelf from NuGet, I saw there was a package called TopShelf.Log4Net. Can you comment on the differences between the two and should I use the latter in my project?
Thanks Tim. That was very helpful. I wanted to automate the emptying of my recycle bin. I found a few tutorials on creating a service out there, but they were overly complicated. IMO. I should have looked at your stuff first, but you know. I already have the method completed for the Recycle bin emptying and now I just need to create the service in the way you showed and I'll be set. Waaaaay easier than the other stuff I found. I also want to build my own bill reminder system. Have the service check my DB every 24 hours and send out an email alert that the bill is coming due. My only hang up is finding a C# service that allows me to send emails. Do you have a vid or a recommendation that would allow me to connect to my Gmail service and send from there? Or others if you believe they're better suited. Thanks again.
Good job Tim. Please do you know how I can deploy this to a remote windows server using Jenkins or Bamboo, and also be able to start, stop and uninstall the service outside of the server?
Great Video. All I want to do is run my console application as a windows service when the computer starts and it will keep on running until the computer is turned off. Can you tell me what modifications I need to do?
Hello Tim, this video tutorial is great. Is there an easy way to use Dependency Injection for the Heartbeat Class e.g with Ilogger and IConfiguration in the CTor ?
A Windows Service does not (should not either) interact with the logged in user. If you want something like that, you want to create an application that runs in the background (like one of the ones you have in your system tray next to the clock).
@@IAmTimCorey Thank you for your reply but I have created open browser demo as you created in this video. Once I have run app from visual studio then it is working but when I have created service of it then it is not working. It's like surprised to me.
Hi Tim, amazing video that saved my life :-). I have a question though. When I create the service that way it is being seen from task manager. Is there any way of preventig the user from closing the application or restart it after it was shut down from task manager? I need this to run constantly on the server and just to be clear I am not writing any malware I just need this application to do it's job permanently. Thank You for Your answer in advance.
No, there isn't. If you wanted to be sure it was always running, you would need to create a second service that restarted the first service if it ever shut down. Just don't do the same thing in reverse for the second service. Otherwise, you will have a problem restarting your machine and you won't be able to update your services.
good night teacher. Is it possible to start in foreground or close a program through services? when run in console the program works fine. when I turn it into a service it doesn't run correctly. my program monitors quinto one thought and started in windows. it monitors screen downtime. if it reaches the ingot time, it closes the program
Great Video. What I want my console application as a service to do is to collect the Performance metrics (System Up Time and Memory usage). Also I want the application to start when the computer is turned on and to stop when the computer is turned off. Can you tell me what modifications I need to do?
Hi thanks for your video , but while trying to install the service it give this message "An exception occurred during the install phase ,Sy" then the Rollback of the installation and the service removed

A service doesn’t have a user interface, so the user cannot browse for a file. However, if you mean that the service looks for a file on its own, that can be done. I have a video on text files on this channel that should show you the code.
Would you still use or recommend Topshelf?
Very nice tutorial I got my solution, Thanks Lot Tim and looking more from you thanks again
You are welcome.
Thanks for sharing your code and knowledge. This will help me a lot... God bless!
You are welcome.
Amazing video, thanks for the help! Keep doing the good work, it helps us a lot! :D
You are welcome.
Great tutorial, it would be interesting make video about using Hangfire with it's dashboard and Topshelf, for example to send e-mails with attachment from some folder.
Thanks for the suggestion.
Many thanks, sumptuous and very clear ...
You are welcome.
Thanks Tim! I think the most important question is: How did you aquire this great knowledge?
Decades of experience and reading LOTS of documentation.
I literally just wrote a service like this a month or so ago for a coworker to monitor a pickup directory that a mainframe deposits batches of Resumes for our HR department in a Zip file. When it sees a new file dropped in, it uncompresses the file into a specified directory structure, logs it's activity and then archives the ZIP for a couple days before delating the processed files. I used the VS WinService template to build it, but just wanted to comment to let everyone know there are a lot of occasions where simple services like this are required. As Tim said, be careful though, if you have an unhandled exception in a service the Windows Service manager just quietly kills the process and logs it to the System log. Also to keep in mind that it can be quite tricky to catch all exceptions in a service due to the way the Windows Service manager and .NET services interact (basically .NET registers the Service base class as the exception handler of last resort, even if you try to replace it). All things considered, Windows Services are not difficult to write, but just remember to be extra careful to look for and handle any potential exceptions, however unlikely you think they are. As a final example, the service I wrote ended up receiving a corrupted ZIP file one day, and as it turns out, I didn't account for one exception type the Zip handler could throw in the case of a corrupted file and the service would die almost instantly after starting because of that. These things are easy to miss :)
Thanks for the advice.
if I had discovered this channel earlier, I would have saved myself a lot of headaches.
Well, I'm glad you found it eventually.
Great video! We use this technique to export web services
That's great!
Great video, thank you! You're annunciation is similar to Rick Scott
Thanks!
Hi Tim,
OnException is not working.
Please suggest. It doesn't catching the exceptions
OnException is not an exception handler. It just allows you to log the exception or do other things to it. You need to still catch the exception properly.
great! So much simpler than BackgroundService hosting.
I wonder why they use Environment.ExitCode vs
static int Main(string[] args)
...
return (int)exitCode;

So nice of you
Hi I've a question, you can run ANY program (.exe) as service as long as you execute "serviceName.exe install start" in the command prompt? or what are the requirements for this command to accept a .exe file as service
No, a service needs to operate without need to interact with the user interface, it should run continually, and it should have methods to properly start and stop it that are based upon the common interface so that the system can properly tell it what to do.
Wow this is crazy useful
Great!
Thanks, Like your videos, simple and clear :-)
Glad you like them!
Great video! Is there a way to tell within code if the program is actually running as a service or from command line?
Amazing. Thank you.
You are welcome.
thankyou very much，it is a simple and good sample.
You are welcome.
thanks for the clear explanation.
You are welcome.
After I installed the cmd prompt multiple times haha but upon checking in Services it is not there. Can you help me?
Hi Tim, I new to C# but worked on Console Application in my previous application. This video helps me to know the basics but here is my problem statements:
1. I have an external application running on python, And this python will call our service with two parameters for eg., 1) json object which holds some infos and 2) path as string indicating the location of trace file (path needed to process in our window service). He will use REST API to call one of the function in our service.
2. The main role of our service is to process the trace file that we receive but here the processing is very slow as compared to calling of our service from the python app.
I was thinking of creating a Job Queue (need to implement in C#, part of service) which will dump these data as the python calls the service and later the we can read it one by one from the job queue.
Is there any video that you can explain the creation of service as API host which can be called from outside.
Note: I already created an Console app which process a file which is defined in a local path.
Great Explanation i really appreciate your time in explaining .. :) I have two questions 1) How can we dependency to the service or how can we start dependency service before new Service. 2)Is there any way,on change in database table data can call the windows service which takes the data changes and process accordingly in Windows service
The service can start other items when it starts. As for having the database trigger a service, you would actually do it the opposite way. The service would listen for changes to the database and then trigger an action.
I want to create a service that send statement every 20minutes... And Also reset a particular counter after 24hrs.., Can I have two Timers on the service one for the 20min and the other for the 24hrs. Thank you.
You can but I would recommend using one timer and doing a check to see if 24 hours has passed. So it would fire the 20 minute event each time (if the timer executed every 20 minutes) and it would identify if it needed to fire the 24 hour event or not. You could make the timer fire every minute and then do lots of different timings.
Thanks you Mr Corey! I like your videos a lot! But now i have a question. How can I create a installer for the windows service Heart Beat ?
Again, one of the best video i cud get to understand how i can create a win service. Thank you so much.
Just want to knw if there's any other way (in built .NET way) to create/install the service without Topshelf?
Thank you very much for your tutorial.
You are welcome!
Amazingly clear!
Thank you!
how can I allow a process to finish before the timer restart the service?
Stop the timer when the process starts and start it again when the process completes.
@@IAmTimCorey Nice tip, simple and easy. Thanks a lot Tim!
Very good tim. God bless you
Thanks, and to you!
Hey tim thanks for this video. Please create video on window application auto updater.. Your last video was good but we want some more examples. Hopefully installshield.
What do you want to see in another video that wasn't covered in the Squirrel video? Just using a different tool?
@@IAmTimCorey Yes tim. there are very fewer and confusing examples of windows application package updation. It could be self updation or intentionally updation of installed windows application. Whatever it would be from your side is always welcomed. We love u tim. A heroic trainer you are.. 😉
What kind of timer would you use to run a service only once at the beginning of the month?
Tim, another great video. I have used Task Scheduler for some similar programs that could just as well be services. Is there any advantage of one over the other?
It is a similar idea but there are a couple benefits of a service. First, they are exposed to the user more readily. Services and their status are listed in the task manager and in the Services portion of the control panel. Also, the user has access to easily choose if a service runs, when it runs, who's permissions it runs under, and more. That gives the user more control over their own system. Finally, a service can keep information between calls more easily. It could have a running counter, a list of things it has done, or anything else that might be useful across calls.
This is amazing. Thank you so much.
You are most welcome. Thanks for watching.
The way you demonstrated here, if you reboot the box, and did not log in, which account will the service be running under?
It doesn't matter if you reboot or not. The service will run under the default account unless you specify an account for it to log in as. The service does not run under your account ever (unless you specifically go in and tell the service to do so (and give it your username and password).
Great video! One question: How would you solve the problem when the service actually runs for longer than the timer we set up and it causes problems. Basically what I am looking for is to run the service only 1 minute after the previous process has been finished. I.e. I do not want to have the same service running and processing my data twice at the same time.
Set Timer AutoReset to false, and call _timer.Start() at the end of TimeElapsed function. That way the Timer will never be running 2 processes or more because of the autoreset spawning new processes without the previous one finishing.
Thank you Tim, I'm new to C# but have written a ton of VBScript over the years - mostly with SQL server stuff. I have a project where I inherited a c# console app that translates HL-7 to and from ASTM messages between a lab instruments. The HL-7 is then passed to Mirth Connect which in turn interfaces with a SQL Server based LIS system. I have heavily modified this c# app to communicate directly with SQL server and skip all the HL-7 and Mirth (JavaScript) code.
My end goal is to convert this app into a service. One of the biggest hurdles I have yet to master is attempting to get much of the code into classes and out of program.cs. Would this be an issue when converting the app into a service?
One of the next steps is to fix the logging. I saw the tutorial you created on Log4Net and thank you for that!
At the 5:30 mark where you are installing TopShelf from NuGet, I saw there was a package called TopShelf.Log4Net.
Can you comment on the differences between the two and should I use the latter in my project?
I believe the TopShelf.Log4Net package just makes it easier to use Log4Net in TopShelf.
Thanks Tim. That was very helpful. I wanted to automate the emptying of my recycle bin. I found a few tutorials on creating a service out there, but they were overly complicated. IMO. I should have looked at your stuff first, but you know. I already have the method completed for the Recycle bin emptying and now I just need to create the service in the way you showed and I'll be set. Waaaaay easier than the other stuff I found. I also want to build my own bill reminder system. Have the service check my DB every 24 hours and send out an email alert that the bill is coming due. My only hang up is finding a C# service that allows me to send emails. Do you have a vid or a recommendation that would allow me to connect to my Gmail service and send from there? Or others if you believe they're better suited. Thanks again.
Check this out - ruclips.net/video/dSXxLyNd2tw/видео.html. Its part of a series but you just need the email info.
@@IAmTimCorey really awesome Tim. Thank you.
Good job Tim. Please do you know how I can deploy this to a remote windows server using Jenkins or Bamboo, and also be able to start, stop and uninstall the service outside of the server?
I don't have examples of that to give you, sorry.
Great Video. All I want to do is run my console application as a windows service when the computer starts and it will keep on running until the computer is turned off. Can you tell me what modifications I need to do?
This video shows you how to do that. Just change your console app to work like mine does and install it as a service.
Thank you very much. Could you please make a lesson about automapper ?
I can add that to the suggestion list.
Hello Tim, this video tutorial is great. Is there an easy way to use Dependency Injection for the Heartbeat Class e.g with Ilogger and IConfiguration in the CTor ?

Very helpful, thank you!
You're welcome!
Thanx for this tutorial👍👍
You are welcome.
I have 1 question, Can we open browser with user specified URL from Windows Service? Please give me proper guideline.
A Windows Service does not (should not either) interact with the logged in user. If you want something like that, you want to create an application that runs in the background (like one of the ones you have in your system tray next to the clock).
@@IAmTimCorey Thank you for your reply but I have created open browser demo as you created in this video. Once I have run app from visual studio then it is working but when I have created service of it then it is not working. It's like surprised to me.
The code can open a browser. The problem is that a service runs under a different user.
@@IAmTimCorey Ohh, so can we pass admin rights to Topshelf code and somehow it can open browser? Sorry for asking question again😅
A million thanks. It's great.
You are welcome.
Hi Tim, amazing video that saved my life :-). I have a question though. When I create the service that way it is being seen from task manager. Is there any way of preventig the user from closing the application or restart it after it was shut down from task manager? I need this to run constantly on the server and just to be clear I am not writing any malware I just need this application to do it's job permanently. Thank You for Your answer in advance.
No, there isn't. If you wanted to be sure it was always running, you would need to create a second service that restarted the first service if it ever shut down. Just don't do the same thing in reverse for the second service. Otherwise, you will have a problem restarting your machine and you won't be able to update your services.
Thank you very much. Very useful
You are welcome.
good night teacher. Is it possible to start in foreground or close a program through services? when run in console the program works fine. when I turn it into a service it doesn't run correctly. my program monitors quinto one thought and started in windows. it monitors screen downtime. if it reaches the ingot time, it closes the program
Great Video. What I want my console application as a service to do is to collect the Performance metrics (System Up Time and Memory usage). Also I want the application to start when the computer is turned on and to stop when the computer is turned off. Can you tell me what modifications I need to do?
That is what a Windows Service does (start when the computer starts). Now you just need it to capture the metrics you need.
Thanks, trying to follow Microsoft docs is always a nightmare.
You are welcome.
Hi thanks for your video , but while trying to install the service it give this message "An exception occurred during the install phase ,Sy" then the Rollback of the installation and the service removed
Read the exception details or check the event log as to why. Sounds like a bug in your code.
