“Public” nested classes or not

Question

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

Answer 1

Another practical example that I have for a valid use of public nested classes is in MVC pattern when I use a viewmodel with an IEnumerable property. for example:

public class OrderViewModel
{
public int OrderId{ get; set; }
public IEnumerable Products{ get; set; }

public class Product {
public string ProductName{ get; set; }
public decimal ProductPrice{ get; set; }
}

}

I use it because I don't want Product class to be re-used outside because it is customized only for that specific viewmodel which contains it. But I can't make it private because the Products property is public.
