✅ .NET Worker service doesn't load appsettings.json into a class

Hello,
I am trying to load configuration values into a class or record, but it doesn't work. The properties remain

null

null

.

I do the following:

builder.Services.Configure<DnsRecordOptions>(builder.Configuration.GetSection("DnsRecords"));

builder.Services.Configure<DnsRecordOptions>(builder.Configuration.GetSection("DnsRecords"));

"DnsRecords:": {
  "ARecord": "0.0.0.0",
},

"DnsRecords:": {
  "ARecord": "0.0.0.0",
},

public record DnsRecordOptions
{
    public required string ARecord { get; init; }
}

public record DnsRecordOptions
{
    public required string ARecord { get; init; }
}

Loading config values this way works in a Web API project, but I don't understand why it wouldn't in an other type of project.
I've also added the

DnsRecords

DnsRecords

configuration to

appsettings.json

appsettings.json

and

appsetting.Development.json

appsetting.Development.json

, but the outcome was the same.
