“Public” nested classes or not

Suppose I have a class \'Application\'. In order to be initialised it takes certain settings in the constructor. Let\'s also assume that the number of settings is so many th

You can use namespaces to relate things that are... related.

For example:

namespace Diner
{
    public class Sandwich
    {
        public Sandwich(Filling filling) { }
    }

    public class Filling { }
}

The advantage of this over using classes as if they were namespaces is that you can optionally use using on the calling side to abbreviate things:

using Diner;

...

var sandwich = new Sandwich(new Filling());

If you use the Sandwich class as if it were a namespace for Filling, you have to use the full name Sandwich.Filling to refer to Filling.

And how are you going to sleep at night knowing that?
