Once the temporary service has started the process, you can then use the Debug menu in Visual Studio to attach to the service process. However, I'm not clear how it is exactly that you are supposed to create the dummy service to load the service process. One thing you could do as a temporary workaround is to launch the debugger as the first line of code in the OnStart.
This will prompt you for the debugger you'd like to use. Simply have the solution already open in Visual Studio and choose that instance from the list. Once you have a service that is installed using installutil. When you manually start the service with the parameter -debugWithVisualStudio or simply -d , it will automatically detect the correct project, and fire up the interactive debugger in Visual Studio:.
When you continue debugging, it will break on the exact line that is throwing the exception. I have added Thread. Sleep ; into my OnStart method and set a breakpoint on the next line of the code. This give me 15 seconds to attach VS debugger to my process after starting the service and allowed me to debug the OnStart method nicely. It's possible to set up a companion project to the Windows Service that runs as a console app, but accesses the service methods using Reflection.
This will prevent accidental or Debugging in Release mode on Production server. Also start VisualStudio as Administrator and allow, that a process can automatically be debugged by a different user as explained here :. In the service code create the service class created above and make the calls needed to start and stop the service in the ServiceBase class.
Just remember to build in Release mode when finished. Of course the conditional compile variable can be anything you like. You could even create seperate projects so the debug form is its own project. You can also try System. Launch method. It helps in taking the debugger pointer to the specified location and you can then debug you code.
Before this step please install your service. If you add Debugger. Launch in your OnStart method and it doesn't work, you could have the same issue I had, namely, the exception was occurring in the constructor so the OnStart was never called. Try adding Debugger. Break inside the problematic method. When the service will start an exception will be thrown and widows should offer to debug it using visual studio. I usually have a console app that pretends to be the SCM e.
Break for debugging when the service has been installed and started via the SCM. It means a bit more work to start with, I have a class lib that contains all the service code, with a class that exposes Start and Stop that the Windows Service class and the console app can both call. Before I go in the topic one advise. Always use log specially if you are server side developer.
Because there are some certain condition which you might not be able to produce while debugging the code in visual studio. Coming back to topic, I use Envoirnment. UserInteractive flag this is really handy see my code below. From visual studio you will get UserInteractive flag set so i would run it as console application, In addition to that even you can run product build by double clicking it and attaching debugger with it if you like to test it.
If seems like a lot of work but it has always worked and makes debugging the code very very easy. You can have all sorts of output added to the form so you can watch it run.

March 4, c Leave a comment. If there is a new record, I then want the script to store the entries from two sp What I am trying to achieve is when clicking on the button it should open a URL in a n Add menu. How to debug the. One thing you could do as a temporary workaround is to launch the debugger as the first line of code in the OnStart System.
Right click on the service name in Windows Service Manager. Select "Properties". Now, when you start the service, it will fire up Visual Studio and break on the line below. It works just fine! The options above did not appear to work on Windows 8. You can add a line of code like this: System.
Break which will bring up a window prompting you to choose which debugger to use to debug, e. I know this is late but this is how we handle debuging Windows services First create a class which will act as the service. Add the appropriate methods for starting, stopping, pausing, etc… Add a windows form to the service project. In the service code create the service class created above and make the calls needed to start and stop the service in the ServiceBase class Open the Program.
EnableVisualStyles ; Application. Error DateTime. In this article, we are not going to concentrate more on developing a Windows Service rather we concentrate on developing a simple service which opens a Notepad process.
Note: In real-time applications we will not be using a Windows Service to open some application like Notepad but more for creating the code that runs behind the scenes and performs background operations which takes a long duration to complete. In this example we are not going to stress out ourselves with creating setup projects or writing too much business logic. Note : In real-time applications we need to add project installer files and create a setup project to deploy the windows service in the server.
Figure 2: Solution structure First things first. The main reason for this article is to identify why we need to do something to make the service that runs an exe.
Why cannot a Windows Service be run in your desktop? Why cannot we be debug it directly? If you are interested in knowing the answers to the preceding questions, do not wait until the end of the article.
Just click on the F5 button and see what happens. Figure 3: Alert You will see the alert by Visual Studio that you cannot start a service from the command line or a debugger.
It says that we need to install this service first to run the service. This is good for when we want to deploy it, right? But, what if we want to debug our code to see whether it is running properly or not? Or if we want to debug our code to fix some issue. Of course if we follow Test Driven Development, we should have done unit testing for the code we have developed.
But what if we need to check the code in the Windows Service classes? Anyways, the answer is simple: You cannot do that directly. Now go to the Service1. It should be something as in the following: Figure 4: Service class before customization Here the OnStart method is what to do to initiate a service and OnStop takes care of what to do stop the service. If we want to make our service code to be executed for every time interval we may have to add a timer control and add the logic that runs whenever the timer time interval is elapsed.
We cannot use the OnStart and OnStop methods to run the service on your desktop and so we need to write our own methods simulating the OnStart and OnStop methods in the preceding figure.
