Have you injected IConfiguration configuration, ILogger logger?

Question

Have you injected IConfiguration configuration, ILogger logger into startup and so usable into controllers api or class?
Thanks.

Please see code for that information.

Start up is here: https://github.com/Dotnet-Boxed/Templates/blob/master/Source/ApiTemplate/Source/ApiTemplate/Startup.cs

We take the "early initialization" approach as seen here https://github.com/serilog/serilog-aspnetcore/blob/dev/samples/EarlyInitializationSample/Program.cs

Thanks, but I don't understand with class you built to read appsettings into a controller.

That is done here https://github.com/Dotnet-Boxed/Templates/blob/master/Source/ApiTemplate/Source/ApiTemplate/CustomServiceCollectionExtensions.cs#L93

I create ConnectionString class like CompressionOption class, but point to new part into appsetting.json and I put it into this

public static IServiceCollection AddCustomOptions(
            this IServiceCollection services,
            IConfiguration configuration) =>
            services
                // ConfigureAndValidateSingleton registers IOptions<T> and also T as a singleton to the services collection.
                .ConfigureAndValidateSingleton<ApplicationOptions>(configuration)
                .ConfigureAndValidateSingleton<CompressionOptions>(configuration.GetSection(nameof(ApplicationOptions.Compression)))
                .ConfigureAndValidateSingleton<ForwardedHeadersOptions>(configuration.GetSection(nameof(ApplicationOptions.ForwardedHeaders)))
                .ConfigureAndValidateSingleton<CacheProfileOptions>(configuration.GetSection(nameof(ApplicationOptions.CacheProfiles)))
                .ConfigureAndValidateSingleton<KestrelServerOptions>(configuration.GetSection(nameof(ApplicationOptions.Kestrel)))
              .ConfigureAndValidateSingleton<ConnectionStringsOptions>(configuration.GetSection(nameof(ApplicationOptions.ConnectionStringsOptions)))
            ;

After I made mapping

        public static IServiceCollection AddProjectRepositories(this IServiceCollection services) =>
            services
                .AddSingleton<ICarRepository, CarRepository>()
                .AddSingleton<ISerialNumbersRepo, SerialNumbersRepo>();

I'm able to read config into the controller,

public class SerialNumbersController : ControllerBase
   { 
       SerialNumbersRepo _repo { get; set; }
       private IConfiguration _config { get; set; }
       private ILogger _logger { get; set; }

       public SerialNumbersController(IConfiguration config)
       {
           _config = config;
           _repo = new SerialNumbersRepo();  
       }

Now, I wish to read IConfiguration from internal class and not a controller.

SerialNumberRepo declaration:

public class SerialNumbersRepo : ISerialNumbersRepo
    {

        private IConfiguration _config { get; set; }
 
        string connString ="";
        //Database db;
        public SerialNumbersRepo(IConfiguration configuration)
        {
            _config = configuration;
     
            connString = _config.GetConnectionString("ConnectionStrings.SqlServer");
      
        }

PS: and the logger?

What does ConnectionStringsOptions look like? And what does your appsettings and appsettings.Development look like? Make sure to redact any secrets.

That is?
