我在 .NET Core Worker Service 中遇到了一些依赖注入问题。请参阅Program.cs文件中的以下代码。

public static void Main(string[] args)
{
    Log.Logger = new LoggerConfiguration()
        .MinimumLevel.Debug()
        .MinimumLevel.Override("Microsof)t", LogEventLevel.Warning)
        .Enrich.FromLogContext()
        .WriteTo.File(@"C:\MyApp_Log\Log.txt")
        .CreateLogger();

    try
    {
        Log.Information("Starting up the service.");
        CreateHostBuilder(args).Build().Run();
        return;
    }
    catch (Exception ex)
    {
        Log.Fatal(ex, "There was a problem starting the service");
        return;
    }
    finally
    {
        Log.CloseAndFlush();
    }

}
public static IHostBuilder CreateHostBuilder(string[] args)
{

    return Host.CreateDefaultBuilder(args)
        .UseWindowsService()
        .ConfigureServices((hostContext, services) =>
        {

            services.AddScoped<IMyAppCoreService, MyAppCoreService>();

            services.AddDbContext<MyAppCSContext>(options => options.UseSqlServer("Data Source=xx.xxx.xx.xxx;Database=Mydb;User ID = sa;Password=mypassword"));


            services.AddHostedService<Worker>();
        })
        .UseSerilog();
}

请参阅下面的Worker.cs …
