Where is ServiceProcessInstaller on Net5?
In .NET 5, the ServiceProcessInstaller
class is not available by default. The ServiceProcessInstaller
class was part of the System.ServiceProcess
namespace in previous versions of .NET Framework for installing Windows services.
Starting with .NET Core 3.0 and continuing with .NET 5 and newer versions, the approach to installing and managing services has changed. The ServiceProcessInstaller
and ServiceInstaller
classes have been replaced by a more platform-agnostic approach using the HostBuilder
and IHostedService
interfaces.
To create and manage services in .NET 5 and later, you can follow the Worker Service pattern. Here's a basic example:
- Create a new .NET Worker Service project in Visual Studio or via the command line:
arduinodotnet new worker -n MyWorkerService
cd MyWorkerService
Open the
Worker.cs
file and implement your service logic within theExecuteAsync
method.In the
Program.cs
file, update theCreateHostBuilder
method to configure the service and define it as a Windows service:
csharpusing Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using System;
using System.Diagnostics;
using System.Linq;
using System.Runtime.InteropServices;
namespace MyWorkerService
{
public class Program
{
public static void Main(string[] args)
{
var isService = !(Debugger.IsAttached || args.Contains("--console"));
var builder = CreateHostBuilder(args.Where(arg => arg != "--console").ToArray());
if (isService)
{
var processModule = Process.GetCurrentProcess().MainModule;
var pathToExe = processModule?.FileName;
var pathToContentRoot = System.IO.Path.GetDirectoryName(pathToExe);
builder.UseWindowsService();
}
var host = builder.Build();
if (isService)
{
host.RunAsService();
}
else
{
host.Run();
}
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureServices((hostContext, services) =>
{
services.AddHostedService<Worker>();
});
}
}
With this approach, you can run your .NET Worker Service as a console application during development by running dotnet run --console
. Then, when you deploy it as a Windows service, use dotnet publish
to generate the necessary artifacts and install the service using appropriate system commands or tools.
Please note that this approach provides a more cross-platform and modern way of creating and managing services in .NET 5 and later versions. It does not use the ServiceProcessInstaller
class specifically, as it was replaced with a more flexible and platform-agnostic approach.
