Example of changes required to Startup.cs to use the reader for the configuration mapping and the bridge as the implementation used by controller

Startup.cs

    public class Startup
    {
       // Other methods omitted for brevity in example
        
       public void ConfigureServices(IServiceCollection services)
        {        
            services.AddMvc();
            services.AddOptions();
            // use the reader class to map the configuration
            services.Configure<MyAppSettingsReader>(Configuration.GetSection("MyAppSettings"));
            // but use the bridge class as the implementation of IMyAppSettings
            services.AddTransient<IMyAppSettings, MyAppSettingsBridge>();
        }
    }
