Core OOP

6 features across 4 C# versions

Object-Oriented Foundation

Full object-oriented design featuring managed classes, structures, explicit interfaces, encapsulation, and runtime polymorphism.

1public interface IWorkable { void PerformWork(); }

2public class Developer : IWorkable {

3 public string Name { get; set; }

4 public void PerformWork() => Console.WriteLine(Name + " is coding.");

Type-safe function pointers allowing operations to be cleanly executed dynamically via native observer/subscriber logic architectures.

1public delegate void WorkHandler(string msg);

2public class Project {

3 public event WorkHandler OnComplete;

4 public void Close() => OnComplete?.Invoke("Done!");

Enables developers to attach custom method interfaces onto pre-existing sealed object instances without altering their source base.

1public static class Extensions {

2 public static bool IsEven(this int num) => num % 2 == 0;

Allows parameters to be captured directly along class headers, removing constructor boilerplate scripts.

1public class IdentityService(string secretKey, int timeoutSeconds) {

2 public bool CheckValid() => secretKey.Length > 0;

Allows extending types with properties, static members, and operators, moving beyond standard extension methods into unified extension blocks.

1public implicit extension PersonExtensions for Person {

2 public string FullName => $"{this.FirstName} {this.LastName}";

Extends partial declaration rules to constructors and events to give source generators seamless hooks into object life cycles.

1public partial class AnalyticsLogger {

2 public partial AnalyticsLogger();
