Step 1: Create a new project Open Visual Studio ? Create a new project . Select Windows Service (.NET Framework) (or Worker Service if you use .NET Core/.NET 6+). Name it something like MyWindowsService . Step 2: Add core service logic In Service1.cs (or your service class), you’ll see two methods: protected override void OnStart(string[] args) { // Code that runs when the service starts WriteLog("Service started."); timer = new System.Timers.Timer(); timer.Interval = 60000; // Run every 1 minute timer.Elapsed += OnElapsedTime; timer.Start(); } protected override void OnStop() { // Code that runs when the service stops WriteLog("Service stopped."); timer.Stop(); } And add this helper method: private System.Timers.Timer timer; private void OnElapsedTime(object sender, System.Timers.ElapsedEventArgs e) { WriteLog("Service running at " + DateTime.Now.ToString()); } private void WriteLog(string message) { string path = AppDomain.CurrentDomain.BaseDirectory + "\Logs"; if (!Directory.Exists(path)) Directory.CreateDirectory(path); string filePath = Path.Combine(path, "ServiceLog.txt"); File.AppendAllText(filePath, DateTime.Now + " - " + message + Environment.NewLine); } This will log timestamps every minute when the service runs. ?? 3. Add Installer (for .NET Framework) If you’re using .NET Framework (not .NET Core), you need to add an installer. In Service1.cs , right-click ? View Designer . Right-click ? Add Installer . This adds ProjectInstaller.cs with two components: serviceInstaller1 serviceProcessInstaller1 Now configure them: // ProjectInstaller.cs public ProjectInstaller() { InitializeComponent(); serviceProcessInstaller1.Account = ServiceAccount.LocalSystem; serviceInstaller1.ServiceName = "MyWindowsService"; serviceInstaller1.DisplayName = "My Windows Background Service"; serviceInstaller1.Description = "This service logs date-time every minute."; serviceInstaller1.StartType = ServiceStartMode.Automatic; } ?? 4. Build and Install the Service Option 1: Install using PowerShell (recommended) Build your project ? find the .exe under bin\Release or bin\Debug . Open PowerShell (Admin) . Run: New-Service -Name "MyWindowsService" -BinaryPathName "C:\Path\To\MyWindowsService.exe" -DisplayName "My Windows Background Service" -Description "Logs time every minute" -StartupType Automatic Then start it: Start-Service MyWindowsService Option 2: Use sc.exe sc create MyWindowsService binPath= "C:\Path\To\MyWindowsService.exe" start= auto sc start MyWindowsService ?? 5. View Logs & Debugging Check your log file in the Logs folder created beside your .exe — you should see lines like: 11/06/2025 10:01:00 AM - Service running at 11/06/2025 10:01:00 AM If not, check the Windows Event Viewer ? Windows Logs ? Application for errors. ?? 6. For .NET Core / .NET 6+ If you're on modern .NET (Core or 6/7/8), use a Worker Service instead. Create via CLI: dotnet new worker -n MyWorkerService Then in Program.cs : using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.Hosting; Host.CreateDefaultBuilder(args) .UseWindowsService() // Important for Windows Services .ConfigureServices((context, services) => { services.AddHostedService (); }) .Build() .Run(); Your Worker.cs will have: protected override async Task ExecuteAsync(CancellationToken stoppingToken) { while (!stoppingToken.IsCancellationRequested) { File.AppendAllText("C:\Logs\WorkerLog.txt", $"Running at: {DateTime.Now}
"); await Task.Delay(60000, stoppingToken); // Every minute } } Then publish: dotnet publish -c Release -r win-x64 And install using: sc create MyWorkerService binPath= "C:\publish\MyWorkerService.exe" ?? 7. Uninstall the Service Stop-Service MyWindowsService Remove-Service MyWindowsService

How to Create a Windows Service Using C# (Step-by-Step) Windows Services are background applications that run without UI and start automatically with Windows. They are ideal for: ? Scheduled tasks ? File monitoring ? Background processing ? Automation jobs ? Queue listeners Step 1: Create the Windows Service Project In Visual Studio : Open Visual Studio Click Create a new project Search for Windows Service (.NET Framework) (Use .NET Framework version 4.7.2+) Give it a name ? e.g., MyWindowsService Click Create You will see a class called: public partial class Service1 : ServiceBase Step 2: Write Service Code Open Service1.cs ? write logic inside OnStart and OnStop . public partial class Service1 : ServiceBase { private System.Timers.Timer timer; public Service1() { InitializeComponent(); } protected override void OnStart(string[] args) { timer = new System.Timers.Timer(); timer.Interval = 5000; // runs every 5 seconds timer.Elapsed += Timer_Elapsed; timer.Start(); } private void Timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { WriteLog("Service is running at: " + DateTime.Now); } protected override void OnStop() { WriteLog("Service stopped."); } private void WriteLog(string message) { string path = @"C:\MyServiceLog.txt"; File.AppendAllText(path, message + Environment.NewLine); } } Step 3: Add Installer (Required!) Right-click inside Service1.cs ? Add Installer It will generate two components: ? ServiceProcessInstaller ? ServiceInstaller Set properties: ServiceProcessInstaller Account = System.ServiceProcess.ServiceAccount.LocalSystem; ServiceInstaller ServiceName = "MyWindowsService"; StartType = Automatic; Step 4: Build the Project Go to: Build ? Build Solution It creates .exe inside: bin\Release\ Step 5: Install the Service (Windows CMD) Open Command Prompt as Administrator . Run: sc create MyWindowsService binPath= "C:\Path\To\MyWindowsService.exe" Start the service: sc start MyWindowsService Stop the service: sc stop MyWindowsService Delete service: sc delete MyWindowsService Alternative Installation (PowerShell) New-Service -Name "MyWindowsService" -BinaryPathName "C:\Path\MyWindowsService.exe" Start-Service MyWindowsService Step 6: Debugging Windows Service Windows services cannot run by double-click . To debug: Option 1 — Temporary Console Mode Add this code: #if DEBUG System.Threading.Thread.Sleep(10000); #endif Or create a console runner. Option 2 — Attach to Process Install service Start service In Visual Studio ? Debug ? Attach to Process Select your service EXE Add breakpoints ? Debug Top Use Cases Use Case Why Windows Service? Auto-backup jobs Runs even when user is logged out File monitoring Continuous background watch Sending emails No UI required Data sync jobs Runs at startup Long-running jobs Stable background processing

Creating a Windows Service in C# is easier than it looks. You mainly need two things: A service class that inherits from ServiceBase A service installer (or use PowerShell to install) Step-by-Step (Modern .NET 6/7/8 Way) This is the recommended method — no need for old ServiceBase boilerplate. 1.Create a Worker Service Project In Visual Studio: File -> New -> Project -> Worker Service This template is made for Windows Services. 2. Add the Windows Service Host In Program.cs : using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.Hosting; Host.CreateDefaultBuilder(args) .UseWindowsService() // Makes it run as a real Windows Service .ConfigureServices(services => { services.AddHostedService (); }) .Build() .Run(); 3. Add Your Service Logic Worker.cs : public class Worker : BackgroundService { private readonly ILogger _logger; public Worker(ILogger logger) { _logger = logger; } protected override async Task ExecuteAsync(CancellationToken stoppingToken) { while (!stoppingToken.IsCancellationRequested) { _logger.LogInformation("Service running at {time}", DateTime.Now); await Task.Delay(5000, stoppingToken); } } } 4. Publish the service dotnet publish -c Release 5. Install the service (PowerShell) Run PowerShell as Administrator: New-Service -Name "MyWindowsService" ` -BinaryPathName "C:\Path\To\publish\MyService.exe" ` -StartupType Automatic Start it: Start-Service MyWindowsService Check status: Get-Service MyWindowsService In One Line: Create a Worker Service ? Call .UseWindowsService() ? Publish ? Install via PowerShell ? Done.

Steps to Create a Windows Service in C# Create a new project ? Choose “Windows Service (.NET Framework)”. Name your project ? e.g. MyFirstWindowsService. Open Service1.cs ? This is your main service file. Write your logic ? Use the OnStart() method to start your code. ? Use the OnStop() method to stop it. Example: protected override void OnStart(string[] args) { File.AppendAllText(@"C:\log.txt", "Service started
"); } protected override void OnStop() { File.AppendAllText(@"C:\log.txt", "Service stopped
"); } Add Installer ? Right-click inside Service1.cs ? Choose “Add Installer”. ? This creates a ProjectInstaller.cs file to help install the service. Build the project ? This will create an .exe file in your bin/Debug or bin/Release folder. Install the service ? Open Command Prompt as Administrator. ? Run: sc create MyService binPath= "C:\Path\To\YourService.exe" Start the service net start MyService Stop or delete later net stop MyService sc delete MyService
