Answer 1

Startup.cs

public IConfiguration _configuration { get; }

public Startup(IConfiguration configuration)
{
       _configuration = configuration;`
}

in Configure Services

services.Configure<ClassName>(Configuration.GetSection("Port")); 

where you want to use

private readonly IOptions<ClassName> _options;

public ConfigService(IOptions<ClassName> options)
{
    _options = options;
}

'ClassName' should be the model to match in appsettings.json.
