GetSection returns null value

[xperiandri]

I have config

{
  "CorsClients": "http://localhost:1089/; http://localhost:4200/",
  "Introspection": {
    "Authority": "https://localhost:44396/",
    "ClientId": "knowledge-base-api",
    "ClientSecret": "846B62D0-DEF9-4215-A99D-86E6B8DAB342"
  }
}

and class

internal class IntrospectionSettings
{
    internal Uri Authority { get; set; }
    internal string ClientId { get; set; }
    internal string ClientSecret { get; set; }
}

Configuration is passed in as follows

public void ConfigureServices(IServiceCollection services) =>
    services.AddAuthentication(OAuthIntrospectionDefaults.AuthenticationScheme)
                .AddCustomOAuthIntrospection(_configuration)

I tried to read it as

var settings = new IntrospectionSettings();
configuration.GetSection("Introspection").Bind(settings);

to make IntrospectionSettings as a struct

It does not work

Then I tried

var settings = configuration.GetSection("Introspection").Value;

It returns null

Also tried this

var settings = configuration.GetSection("Introspection")
               .Get<IntrospectionSettings>();

Questions:

1. Why section cannot be a struct?
2. How can Value property of IConfigurationSection be null but not JSON object?

[korzh]

The problem is in internal access modifier for properties in your IntrospectionSettings class. Make it public and it will work well.

Value property is always null for IConfigurationSection. Use GetChildren method to get the list of section's items.
