DependencySingleton<T>

Represents an abstract base class for creating thread-safe singleton instances with optional dependency injection support. This pattern can be utilized in both dependency injection (DI) and non-DI scenarios. Example usage:

 //File ISampleSerivce.cs
 public interface ISampleService
 {
     Task StandardDelayAsync(CancellationToken cancellationToken = default);  void StandardDelay();
 }

 //File DSSampleSerivce.cs
 public partial class SampleService : DependencySingleton<SampleService>, ISampleService , IDependencySingleton
 {
     public SampleService(ILogger<SampleService> logger, IConfiguration configuration) : base(logger, configuration) { }
 }

 //File SampleSerivce.cs
 public partial class SampleService : DependencySingleton<SampleService>, ISampleService , IDependencySingleton
 {
     public void StandardDelay() { StandardDelayAsync(CancellationToken.None).GetAwaiter().GetResult(); }
     public async Task StandardDelayAsync(CancellationToken cancellationToken = default)  { await Task.Delay(5000, cancellationToken); }
 }

 //File Program.cs
 static async Task Main(string[] args)
 {
    SampleService.Instance.SetMinimumLogLevel(LogLevel.Trace);
    // The ILogger<SampleService> logger and IConfiguration configuration will be initialized with their own service stacks.
    SampleService.Instance.StandardDelay();

    // Normal DI usage
    var host = Host.CreateDefaultBuilder(args)
        .ConfigureLogging((context, logging) => {  logging.AddConsole(); logging.AddDebug(); })
        .ConfigureServices((context, services) => { services.AddSingleton<ISampleService,SampleService>(); services.AddSingleton<IMyService,MyService>(); });
    await host.Build().RunAsync();
 }

 //Service usage
 public class MyService
 {
     private readonly ISampleService sampleService;

     public MyService(ISampleService sampleService)
     {
         this.sampleService = sampleService;
     }

     public async Task UseSample()
     {
         await sampleService.StandardDelayAsync();
     }
}
