1. Embrace Primary Constructors

I remember refactoring a class with multiple constructors, each initializing the same properties. It was a mess. Then, I discovered primary constructors in C#. They let you define parameters directly in the class declaration, reducing boilerplate code.

public class Person(string name, int age)  
{  
    public string Name { get; } = name;  
    public int Age { get; } = age;  
}

This simple change made my code more concise and readable.

2. Use Collection Expressions

One day, I was working on a project where I needed to initialize multiple collections. The old syntax felt clunky. C# 14 introduced collection expressions, which simplified the process.

List<int> numbers = [1, 2, 3, 4, 5];

It felt like magic — less typing, more clarity.
