Debug service windows c#

Net Core 6. Create A. Understanding Thread Starvation in. NET Core Applications. Exploring Numeric Streams In Java. What Is The Metaverse. Microservice Circuit Breaker Pattern. Handle the Timer Elapsed event. This completes the changes we have to make in the service class. Now we need to make changes in the Program. The main part of achieving the goal is to use preprocessor directives. CS file:. Put the actual code already available in the Main method between else and endif. Finally our code looks as in the following:.

Notice that I have set the Thread. Sleep method to double the time of the timer interval so that it executes only once and then the application is stopped. If you want the code to run in an infinite time period then modify the time from Thread. Sleep to Thread.

Sleep Timeout. Infinite ; Now let us see how our code runs. Make sure that you set the application running mode as "Debug". Figure 5: Debug mode Press F5.

It should open a Notepad file and then it should be done. RunInteractive args. Nice solution Anders! Great solution indeed. I created a simple extension for ServiceBase[] as David suggested which allows to run services in just one line of code: pastebin. It really makes debugging a windows service a breeze. Chazt3n Make sure that your project output type is set to "Console Application". As for the service installation, It does not matter which output type is selected, the behavior is the same.

Still a great solution! The only thing I would add as shown in the walk through is to make sure you go into the project's properties and change the output type to Console Application before you try to compile and run. Also, for this to work properly for me I ended up having to run the application using the start command. Show 7 more comments.

So you select the Visual Studio instance you've opened earlier instead: After you have clicked Yes , after a while Visual Studio will show the yellow arrow right in the line where the Debugger.

Note that If you build a Release, then the debug code is automatically removed and the service runs normally. Matt Matt Out of curiousity, do you know if there is a timeout for user interaction with the Debugger.

Launch user prompt? As described, base. RequestAdditionalTime will prevent the service control from terminating the service for 10 minutes if it does not call base. OnStart args within that timespan. Apart from that, I remember that UAC will also abort if you don't enter the admin credentials after a while I don't know how many seconds exactly, but I think you have to enter it within a minute, else UAC aborts , which will terminate the debug session.

I found this to be the best method for debugging CustomCommand messages. Paul van Brenk Paul van Brenk 7, 2 2 gold badges 31 31 silver badges 37 37 bronze badges. I used to use this approach too, but I think a combination of this and the answer above works a treat.

OnDebug ; System. Sleep System. Infinite ; And it will run just like a console application, once things go OK you can change the mode Release and the regular else section will trigger the logic.

I was looking for this answer, dunno why it was ranked so low. Explained the code to help others or possibly more comments ; — Vinod Srivastav. Threading; using System. Infinite , Timeout. Change TimeSpan. Parse "" , TimeSpan. OnStart Thread. Sleep Timeout. Thomas Bratt Thomas Bratt Still runs as a normal service in release builds. Combine this with the solution above by Christian K. UserInteractive" property and the solution is really clean and simple.

OnStart is protected and you can't modify the access level : — Eduard Luca. You can also start the service through the command prompt sc. What language are you using? Use the TopShelf library. Start ; s. RestartService delayInMinutes: 0 ; rc. To install service, type in cmd "console.

Their licensing was too confusing to understand — Alex Gordon. They use Apache License afaik. Topshelf is the easiest way I have used to develop and debug windows services. Super easy to use. Develop as a console application. Install as a service with one command line switch.

Highly recommended. TopShelf saved me tons of time. This exists in the "Image File Execution Options" registry key and is incredibly useful. I think you'll need to tweak the Service settings to enable "Interact with Desktop". I use this for all types of debugging, not just services. The other option, is to separate the code a bit, so that the service part is interchangable with a normal app startup.

That way, you can use a simple command line flag, and launch as a process rather than a Service , which makes it much easier to debug. Hope this helps.

Nir Nir Moving the pointer cannot revert your application to an earlier app state. With the debugger paused at the SendMessage method call in the for loop, select F11 three times to step into the SendMessage method and to move past the Console.

WriteLine method after executing it. Use the mouse to grab the yellow arrow or execution pointer in the left margin , and then drag the pointer up one line. WriteLine method, and you'll see a duplicate line in the console window output.

Use this feature with care. You'll see a warning in the tooltip of the execution pointer about the possibility of unintended consequences.

You might see other warnings, too. Moving the execution pointer can't revert your application to an earlier state. For more about the changing the execution flow, see Move the pointer to change the execution flow. In this tutorial, you've learned how to start the debugger, step through code, and inspect variables.

You might want to get a high-level look at debugger features along with links to more information. First look at the debugger. Skip to main content.
