当类没有公共构造函数时，会发生NoConstructorsFoundException。要解决此问题，请确保SupportRequestModelFactory类中有公共构造函数，并在公共构造函数的参数中传递所有必需的服务。
下面是一个例子：

public partial class SupportRequestModelFactory : ISupportRequestModelFactory
    {
        private readonly ILocalizationService _localizationService;
        private readonly ILocalizedModelFactory _localizedModelFactory;

        public SupportRequestModelFactory(
            ILocalizationService localizationService,
            ILocalizedModelFactory localizedModelFactory)
        {
            _localizationService = localizationService;
            _localizedModelFactory = localizedModelFactory;
        }
    }

此外，请确保您已经在ConfigureServices中注册了模型工厂。

public class NopStartup : INopStartup
    {
        public virtual void ConfigureServices(IServiceCollection services, IConfiguration configuration)
        {
            services.AddScoped<ISupportRequestModelFactory, SupportRequestModelFactory>();
        }
    }
