System.NotSupportedException：“不支持返回 System.IServiceProvider 的配置服務。” 帶結構 Map

Question

I am trying to inject the structure map into .net core 3.0 web API but Continuously I am getting the error in my Program.cs class. 沒找到map結構相關的解決方案，大家討論Autofac

public class Program
    {
        public static void Main(string[] args)
        {
            CreateHostBuilder(args).Build().Run();
        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });

    }

我的啟動 class 是

 public class Startup
    {
        public IServiceProvider ConfigureServices(IServiceCollection services)
        {

            services.AddControllers();

            var container = new Container();
            container.Configure(config =>
            {
                config.AddRegistry(new CustomRegistry());
                config.Populate(services);
            });

            return container.GetInstance<IServiceProvider>();
        }


        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseRouting();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });
        }
    }

如果您有任何建議，請告訴我。 感謝您提前提供幫助！

Program.cs 添加 AutofacServiceProviderFactory 就像在代碼下

public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
        .ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.UseStartup<Startup>();
        }).UseServiceProviderFactory(new AutofacServiceProviderFactory());

然后在 StartUp.cs 中添加 ConfigureContainer

public void ConfigureContainer(ContainerBuilder builder)
{
    builder.RegisterAssemblyTypes(typeof(Program).Assembly).
        Where(x => x.Name.EndsWith("service", StringComparison.OrdinalIgnoreCase)).AsImplementedInterfaces();
            builder.RegisterDynamicProxy();

}

在 dotnet core 3.0 中改變 ioc 方式
