安装包：Microsoft.AspNetCore.Hosting.WindowsServices、Microsoft.Extensions.Hosting、Microsoft.Extensions.Hosting.WindowsServices、Microsoft.Extensions.Logging.Log4Net.AspNetCore
新建Configs/log4net.config

using Com.Chinahorn.Exchange.WorkerService;

IHost host = Host.CreateDefaultBuilder(args)
    .UseWindowsService()
    .ConfigureLogging(logging => logging.AddLog4Net("Configs/log4net.config"))
    .ConfigureServices(services =>
    {
   
        services.AddHostedService<Worker>();
    })
    .Build();

await host.RunAsync();
