Dotnet

The dotnet command-line interface is a cross-platform toolchain for developing, building, running, and publishing .NET applications.

Publish

The dotnet publish command publishes the application and its dependencies to a folder for deployment to a hosting system.

Argument	Description
`-p:PublishSingleFile=true`	Packages into a single-file executable.
`--arch`	Target architecture. `x64`
`--configuration`	Build configuration. `Debug` `Release`
`--framework`	Target framework. `net6.0`
`--output`	Output directory. `Build`
`--os`	Target operating system. `win`
`--self-contained`	Packages the .NET runtime with the application so the runtime doesn't need to be installed on the target machine. `true` `false`

Worker Services

Worker services are applications that can be used to queue operations in the background, schedule operations to execute at a later time or perform processor-intensive tasks. The project template Worker Service Template is available in Visual Studio and dotnet CLI.

Windows services are supported worker services.

Install the NuGet package Microsoft.Extensions.Hosting.WindowsServices.
Modify the program to use the windows service:

IHost host = Host.CreateDefaultBuilder(args)
    .UseWindowsService(options =>
    {
        options.ServiceName = "My Windows Service";
    })
    .ConfigureServices(services =>
    {
        services.AddHostedService<Worker>();
    })
    .Build();

Once the worker service is built, the windows service can be controlled using the Service Control application.

Create

sc.exe create "My Service" binpath="path/to/service.exe"

Start

sc.exe start "My Service"

Stop

sc.exe stop "My Service"

Delete

sc.exe delete "My Service"
