You can get AppSettings in your FooService by injecting IOptions<AppSettings> DI service in it's constructor.

The IOptions<> interface is part of something called Options Model which is used for accessing POCO style settings(ex: your AppSettings) across your application. The calls like services.Configure<AppSettings>( and services.Configure<FacebookAuthenticationOptions>(options => in your above example, actually register DI services which in turn are used by a DI service called OptionsManager when resolving requests for IOptions<>.

Example:

public class FooService
{
    private readonly AppSettings _settings;

    public FooService(IOptions<AppSettings> options)
    {
        _settings = options.Options;
    }

    ....
    ....
}
