Windows service .net

NET applications. To do this we want to:. This method does a couple of things. Secondly, it configures your host to use a ServiceBaseLifetime. First, lets publish the application. We will install the Windows Service in-place, meaning the exe will be locked whenever the service is running.

The publish step is a nice way to make sure all the files I need to run the service are in one place and ready to be installed. Then we can use the sc utility in an admin command prompt. Instead you should create a service account and run the windows service as that account. We will not talk about that here, but there is some documentation on the ASP.

The logging system has an Event Log provider that can send log message directly to the Windows Event Log. To log to the event log you can add the Microsoft. EventLog package and then modify your Program. In upcoming previews we plan to improve the experience of using Workers with Windows Services by:.

We hope you try out this new template and want you to let us know how it goes, you can file any bugs or suggestions here. Comments are closed. They are the same thing.

This is the progression of those features :. I plan to do a post about that next, short story is that with something like systemd you create a service config file and it runs fine.

But there are a bunch of interesting details to dig into. You should be able to, the logging is exactly the same system as in ASP. I should have. So I will go do that and report back. NET specific stuff. But it looks like it is :. This is great! Is there a way to detect with the Microsoft.

WindowsServices NuGet package that my application is running as a Windows Service vs running as a console app? You can attach the debugger only to a running service. The attachment process interrupts the current functioning of your service; it doesn't actually stop or pause the service's processing.

That is, if your service is running when you begin debugging, it is still technically in the Started state as you debug it, but its processing has been suspended. After attaching to the process, you can set breakpoints and use these to debug your code. Once you exit the dialog box you use to attach to the process, you are effectively in debug mode. You can use the Services Control Manager to start, stop, pause and continue your service, thus hitting the breakpoints you've set.

You can later remove this dummy service after debugging is successful. This article covers debugging a service that's running on the local computer, but you can also debug Windows Services that are running on a remote computer. See Remote Debugging. Debugging the OnStart method can be difficult because the Services Control Manager imposes a second limit on all attempts to start a service. For more information, see Troubleshooting: Debugging Windows Services. To get meaningful information for debugging, the Visual Studio debugger needs to find symbol files for the binaries that are being debugged.

If you are debugging a service that you built in Visual Studio, the symbol files. If you are debugging a service that you didn't build, you should first find symbols for the service and make sure they can be found by the debugger. See Specify Symbol. If you're debugging a system process or want to have symbols for system calls in your services, you should add the Microsoft Symbol Servers. See Debugging Symbols. Install your service. For more information, see How to: Install and Uninstall Services.

For more information, see How to: Start Services. On the menu bar, choose Attach to Process from the Debug or Tools menu. For information and advice on deployment scenarios, see. NET Core application deployment. If the service only executes background tasks for example, hosted services , specify the Worker SDK in the project file:. Framework-dependent deployment FDD relies on the presence of a shared system-wide version of.

NET Core on the target system. If using the Web SDK , a web. To disable the creation of the web. Self-contained deployment SCD doesn't rely on the presence of a shared framework on the host system. The runtime and the app's dependencies are deployed with the app. For more information, see. To create a user account for a service, use the New-LocalUser cmdlet from an administrative PowerShell 6 command shell. Provide a strong password when prompted.

For more information, see Microsoft. LocalAccounts and Service User Accounts. An alternative approach to managing users when using Active Directory is to use Managed Service Accounts.

Use PowerShell commands to register a service. From an administrative PowerShell 6 command shell, execute the following commands:. Services that interact with requests from the Internet or a corporate network and are behind a proxy or load balancer might require additional configuration.

For more information, see Configure ASP. NET Core to work with proxy servers and load balancers. By default, ASP. Use of the ASP. The system32 folder isn't a suitable location to store a service's files for example, settings files. Use one of the following approaches to maintain and access a service's assets and settings files. Use IHostEnvironment. The app's default settings files, appsettings. NET Core projects.

Many startup errors don't produce useful information in the event logs. You can find the cause of some errors by running the app at a command prompt on the hosting system. To log additional detail from the app, lower the log level or run the app in the Development environment. A functioning app may fail immediately after upgrading either the.

In some cases, incoherent packages may break an app when performing major upgrades. Most of these issues can be fixed by following these instructions:. Clear the package caches by executing dotnet nuget locals all --clear from a command shell. Clearing package caches can also be accomplished with the nuget.

A crash dump is a snapshot of the system's memory and can help determine the cause of an app crash, startup failure, or slow app. Run the EnableDumps PowerShell script with the application executable name:. After the crash has occurred, run the DisableDumps PowerShell script :. After an app crashes and dump collection is complete, the app is allowed to terminate normally.

When an app hangs stops responding but doesn't crash , fails during startup, or runs normally, see User-Mode Dump Files: Choosing the Best Tool to select an appropriate tool to produce the dump. A dump can be analyzed using several approaches.

The app requires package references for Microsoft. WindowsServices and Microsoft. To test and debug when running outside of a service, add code to determine if the app is running as a service or a console app.
