The `SettingsHelper` is an agnostic way to access settings values uniformly through code. The accessor methods are controlled by the consumer. Documentation has been a bit wonky. I changed the max number of version number components allowed, so each new build should not create new changes on every single bit of documentation now.

interface IEqualityComparer<'T>
end

Example
using System; using System.Collections.Generic; using System.Linq; class Program { static void Main(string[] args) { var people = new List<Person> { new Person { Name = "Alice", Age = 30 }, new Person { Name = "Bob", Age = 30 }, new Person { Name = "Charlie", Age = 35 } }; var comparer = new PropertyComparer<Person, int>(p => p.Age); var distinctPeople = people.Distinct(comparer).ToList(); foreach (var person in distinctPeople) { Console.WriteLine($"{person.Name} - {person.Age}"); } } } class Person { public string Name { get; set; } public int Age { get; set; } }

| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode() | Serves as the default hash function. (Inherited from Object) |
| GetHashCode(T) | Returns a hash code for the specified object. |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
Fields
| expression | The expression to retrieve the property. |
