bool IsPrime(int number)

{

Copilot might suggest:

csharp

CopyEdit

    if (number <= 1) return false;

    for (int i = 2; i <= Math.Sqrt(number); i++)

        if (number % i == 0)

            return false;

    return true;

}

Just hit Tab, and boom—you’ve saved a few minutes already!

Scrutor the built-in Dependency Injection (DI)

By Tareq Marji -
  Scrutor is a lightweight .NET library that extends the built-in Dependency Injection (DI) system in ASP.NET Core (or any .NET application that uses Microsoft.Extensions.DependencyInjection) by providing assembly scanning and automatic registration of services . Key Features of Scrutor Assembly Scanning Automatically registers services by scanning assemblies instead of manually specifying each one. This is helpful in large applications or when following clean architecture or DDD patterns. Service Registration by Convention You can register services based on naming conventions or interface implementation. For example, register all classes that implement a specific interface. Decorators Scrutor supports applying the decorator pattern easily through DI, allowing you to wrap services (e.g., for logging, validation, etc.) without modifying the core implementation.   Example Usage 1. Basic Scanning and Registratio...

🧅 Understanding the Onion Architecture: A Clean Approach to Building Scalable Applications

By Tareq Marji -
  When building modern, maintainable software applications, how you organize your code matters a lot. Over time, developers have learned that tightly coupled systems become hard to maintain, test, and evolve. Enter the Onion Architecture — a clean, layered architectural pattern that addresses many of these challenges by enforcing strict separation of concerns. 📌 What is Onion Architecture? The Onion Architecture , introduced by Jeffrey Palermo, is an architectural pattern designed to build maintainable, testable, and loosely coupled applications. Its core idea: The application is structured in concentric layers (like an onion), where dependencies always point inward toward the core. 🧅 Layers of Onion Architecture Here’s a quick breakdown of the typical layers from inside out: 1. Core (Domain) Layer Holds the business logic , domain entities, and domain services. No dependencies on other layers. Contains pure domain models (POCOs). ...

🔌 Extension Methods in C#: Power Up Your Code Without Modifying It

By Tareq Marji -
Have you ever wanted to add a method to an existing class (like string, DateTime, or even your own types) — without changing its source code? That’s exactly what extension methods in C# are for. 🚀 What Is an Extension Method? An extension method lets you "extend" an existing type (class or struct) with new methods , without modifying the type itself . ✅ It feels like you're adding a method to the type ✅ But you're really writing a static method with a special syntax 🧪 Real-Life Example Let’s say you want to capitalize the first letter of a string: ❌ Without Extension: csharp public static class StringUtils {     public static string Capitalize(string value)     {         if (string.IsNullOrEmpty(value)) return value;         return char.ToUpper(value[0]) + value.Substring(1);     } } Usage: csharp string name = "...

Understanding Dependency Injection: A Modern Guide for Developers

By Tareq Marji -
In today’s fast-paced software development world, building scalable, testable, and maintainable applications is a top priority. One of the core principles that help achieve this is Dependency Injection (DI) . Whether you're working in .NET, Java, Python, or another modern framework, DI is a foundational design pattern that every developer should master. What is Dependency Injection? Dependency Injection is a design pattern that deals with how components or objects acquire their dependencies. Rather than creating dependencies directly within a class, they are provided (injected) from the outside. In simple terms, instead of a class instantiating its own dependencies, they are passed to it — usually through the constructor, method parameters, or properties. Without DI (Tightly Coupled Code): csharp CopyEdit public class OrderService {     private readonly PaymentService _paymentService = new PaymentService();       public void Proce...

🔐 JWT (JSON Web Token) Explained: Secure Your APIs the Modern Way

By Tareq Marji -
  If you're building APIs or modern web apps, you've probably heard of JWT . But what is it, really? In this post, we'll break down: What JWT is How it works Why and when to use it How to implement it in a .NET Core API 🚀 What is JWT? JWT stands for JSON Web Token . It’s a compact, URL-safe token used to securely transmit information between two parties — typically between a client and a server. Unlike traditional session-based authentication (which stores session data on the server), JWT is stateless . All the information is stored in the token itself . 🧱 Structure of a JWT A JWT has three parts , separated by dots: xxxxx.yyyyy.zzzzz 1. Header Specifies the type of token and the algorithm used to sign it. json {   "alg": "HS256",   "typ": "JWT" } 2.
