需要更改步骤№2

        public void ConfigureContainer(ContainerBuilder builder)
    {
        //get settigns as object from config
        var someSettings= Configuration.GetSection(typeof(SomeSettings).Name).Get<SomeSettings>();                                                    
        //put settings into module constructor 
        builder.RegisterModule(new AutofacModule(someSettings));
    }

我不知道是否是***实践方式，但是有效。

I don't know is "best practise" way or not, but it works.
