I try to bind a config section to a custom type. When binding the value SiteId is assigned, but not the other values, there’s three string properties that’s not set (Version, Email, Name).

Config:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*",
  "Assets": {
    "SiteId": 14,
    "Version": "2.3.12",
    "Email": "[email protected]",
    "Name":  "Creator framework"
  }
}

AssetsConfig.cs:

public class AssetsConfig
{
    private readonly IConfiguration _config;

    public AssetsConfig(IConfiguration _config)
    {
        _config = raw;
    }

    public int SiteId { get; set; }
    public string Culture { get; set; }
    public IConfiguration Config => _config;
    public string Version { get; }
    public string Email { get; }
    public string Name { get; }
    public string ReleaseDate { get; }
}

Binding:

AssetsConfig cnf = new Assets.AssetsConfig(builder.Configuration);
builder.Configuration.Bind(AssetsStatics.ConfigSectionName, cnf);

_ = builder.Services
    .AddOptions()
    .Configure<IConfiguration>(builder.Configuration)
    .AddSingleton(cnf);

Confing element (cnf) after binding:

{SL.Assets.AssetsConfig}
    Config: Sections = 102
    Culture: null
    Email: null
    Name: null
    ReleaseDate: null
    SiteId: 14
    Version: null
    _raw: Sections = 102

As you can see the property SiteId is assigned correctly, but not the others.

Any ideas?
