                   .SetBasePath(Directory.GetCurrentDirectory())
                   .AddJsonFile("appsettings.json", optional: true)
                   .Build();
            CreateHostBuilder(args).Build().Run();
        }
        private static IConfigurationRoot config;
        public static IHostBuilder CreateHostBuilder(string[] args) =>
         Host.CreateDefaultBuilder(args)
             .ConfigureWebHostDefaults(webBuilder => {
                 //Ioc use LightInject
                 webBuilder.UseLightInject();
                 var isProduction = false;
                 webBuilder.ConfigureKestrel((context, options) => {
                     options.Limits.MaxRequestBodySize = Setting.FileUploadLimit;
                     isProduction = context.HostingEnvironment.IsProduction();
                 });
                 webBuilder.UseStartup<Startup>();
                 if (isProduction) {
                     var url = config.GetSection("Url").Value;
                     webBuilder.UseUrls(url);
                 }

             });
    }
// added in Startup
     public void ConfigureContainer(IServiceContainer container) {
            //TODO:container.RegisterFrom<CompositionRoot>();

        }

Hi, I've had similar issue with .NET Core 3.1

You need to add

.UseServiceProviderFactory(new LightInjectServiceProviderFactory())

to your HostBuilder chain, before .ConfigureWebHostDefaults(..)
LightInjectServiceProviderFactory is from LightInject.Microsoft.DependencyInjection nuget package.
