netcore下开发windows服务如果是web项目的话，由于aspnetcore本身是支持的，把默认的host.Run改为host.RunAsService就可以了。

但是普通的netcore的控制台项目我终于找到了如下方式来实现：

1. Microsoft.Extensions.Hosting

2. System.ServiceProcess.ServiceController

public class ServiceBaseLifetime : ServiceBase, IHostLifetime{private readonly TaskCompletionSource _delayStart = new TaskCompletionSource();

public ServiceBaseLifetime(IApplicationLifetime applicationLifetime)    {        ApplicationLifetime = applicationLifetime ?? throw new ArgumentNullException(nameof(applicationLifetime));    }

private IApplicationLifetime ApplicationLifetime { get; }

public Task WaitForStartAsync(CancellationToken cancellationToken)    {        cancellationToken.Register(() => _delayStart.TrySetCanceled());        ApplicationLifetime.ApplicationStopping.Register(Stop);

new Thread(Run).Start(); // Otherwise this would block and prevent IHost.StartAsync from finishing.return _delayStart.Task;    }

private void Run()    {try        {            Run(this); // This blocks until the service is stopped.            _delayStart.TrySetException(new InvalidOperationException("Stopped without starting"));        }catch (Exception ex)        {            _delayStart.TrySetException(ex);        }    }

public Task StopAsync(CancellationToken cancellationToken)    {        Stop();return Task.CompletedTask;    }

// Called by base.Run when the service is ready to start.protected override void OnStart(string[] args)    {        _delayStart.TrySetResult(null);base.OnStart(args);    }

// Called by base.Stop. This may be called multiple times by service Stop, ApplicationStopping, and StopAsync.// That's OK because StopApplication uses a CancellationTokenSource and prevents any recursion.protected override void OnStop()    {        ApplicationLifetime.StopApplication();base.OnStop();    }}

public static class ServiceBaseLifetimeHostExtensions{public static IHostBuilder UseServiceBaseLifetime(this IHostBuilder hostBuilder)    {return hostBuilder.ConfigureServices((hostContext, services) => services.AddSingleton<IHostLifetime, ServiceBaseLifetime>());    }

public static void RunAsService(this IHostBuilder hostBuilder)    {        hostBuilder.UseServiceBaseLifetime().Build().Run();    }

public static Task RunAsServiceAsync(this IHostBuilder hostBuilder)    {return hostBuilder.UseServiceBaseLifetime().Build().RunAsync(CancellationToken.None);    }}

public class TestService: IHostedService,IDisposable{readonly System.Timers.Timer tmBak = new System.Timers.Timer();

public TestService()    {        tmBak.Interval = 1000;//1秒执行1次        tmBak.AutoReset = true;//执行1次false,一直执行true        tmBak.Enabled = true;        tmBak.Elapsed += (sender, eventArgs) =>        {using (StreamWriter sw = new StreamWriter("D:\\log.txt",true))            {                sw.WriteLine($"AntDeploy Windows服务：{DateTime.Now:yyyy-MM-dd HH:mm:ss}");            }        };    }

public Task StartAsync(CancellationToken cancellationToken)    {        tmBak.Start();return Task.CompletedTask;    }

public Task StopAsync(CancellationToken cancellationToken)    {        tmBak.Stop();return Task.CompletedTask;    }

public void Dispose()    {this.tmBak.Dispose();    }}

class Program{// P/Invoke declarations for Windows.[DllImport("kernel32.dll")] static extern IntPtr GetConsoleWindow();[DllImport("user32.dll")] static extern bool IsWindowVisible(IntPtr hWnd);public static bool HaveVisibleConsole(){return RuntimeInformation.IsOSPlatform(OSPlatform.Windows) ?IsWindowVisible(GetConsoleWindow()):Console.WindowHeight > 0;}

private static async Task Main(string[] args)    {var pathToExe = Process.GetCurrentProcess().MainModule.FileName;var pathToContentRoot = Path.GetDirectoryName(pathToExe);        Directory.SetCurrentDirectory(pathToContentRoot);

var isService = !(Debugger.IsAttached || args.Contains("--console"));

if (HaveVisibleConsole()) isService = false;var builder = new HostBuilder()            .ConfigureServices((hostContext, services) =>            {                services.AddHostedService<TestService>();            });

if (isService)        {await builder.RunAsServiceAsync();        }else        {await builder.RunConsoleAsync();        }    }}

AntDeploy是我开发的一款开源一键部署vs插件(也是支持脱离vs单独使用的一个开源工具)

开源地址：https://github.com/yuzd/AntDeployAgent

添加一个环境 名字叫 测试 然后 在 测试环境里面添加 windows服务器 这里我做测试就添加就是我本机，注意Host里面是填写格式为：ip:端口号

注意：Token不是windows服务器的密码！！！是安装agent后，agent的配置文件里面配置的Token(你自己自定义配置的)
注意：Port不是你要发布的项目的端口号！！！是安装agent后，agent的配置文件里面配置的端口号(你自己自定义配置的)
点击【Connect Test】按钮进行确认agent可以成功链接，否则会发布失败
如果【Connect Fail】失败 请查看 #10

进入 WindowsService Tab界面

Sdk类型选择 netcore
ServiceName 填写上面我们设置的名称：[TestService]

点击 【Deploy】按钮进行发布

确认服务器无误 点击 【是】开始执行一键部署
如果发布出现错误会出现下图所示：

可以在Log里面查看失败原因是因为我部署agent没有用管路员权限 报权限不足失败 需要用管理员权限运行agent才行

部署成功 如下图：

查看D盘下是否log.txt是否正常每隔1秒写入了当前时间

这里演示的是windows服务上没有这个service
所以自动创建了。
如果service已存在的情况 Deploy 就会全量覆盖 不会重新创建site的。
如果想要覆盖时排除指定文件 可以在 Setting Tab界面的IgnoreList里面增加(支持正则)
