Interviewers evaluate:✔ Architecture thinking✔ Scalability & performance✔ OOPS + SOLID usage✔ Real-world trade-offs✔ Communication skills This article covers most asked system design interview questions with clear explanations and design approach, not just theory. 🔹 1. What is System Design? System Design … Read more
When writing scalable applications in C#, developers often compare Singleton vs Static Class. Both restrict object creation and provide global access, but their purpose and memory usage are completely different. This article explains the similarities, differences, memory management, advantages, and real-time examples to help you choose the right approach. What Is a Static Class in … Read more
💡 Introduction In today’s fast-moving software world, businesses often face the challenge of integrating legacy systems with modern applications. A perfect example is when a new billing system works with JSON, but the old billing system still processes only XML. Instead of rewriting or discarding the old code, we can solve this compatibility issue using … Read more
✅ Introduction In software design, object creation often becomes complex—especially when handling deeply nested or repeatable structures. Two powerful creational design patterns in C#, the Builder Pattern and Prototype Pattern, solve these challenges elegantly. When combined with generics, these patterns provide a type-safe, reusable, and flexible approach to object construction and cloning. In this article, … Read more
✅ Introduction The Builder Design Pattern is one of the most popular Creational Design Patterns in C#. It helps construct complex objects step by step and allows creating different variations of an object using the same construction process. In this guide, we’ll cover: 🔧 Why Use the Builder Design Pattern? You should consider using the … Read more
In large-scale applications, you often need to create families of related objects without tightly coupling your code to specific implementations. The Abstract Factory Design Pattern is designed exactly for this purpose. This is one of the most popular Creational Design Patterns in C#, and it provides a framework for creating entire product families while keeping … Read more
While the Singleton pattern can be useful in some scenarios (like logging or configuration), it is often considered an anti-pattern — especially in large, complex applications. Here’s why Singleton is considered an anti-pattern in many software engineering circles: 1. It Introduces Global StateSingletons behave like global variables. This makes it easy to access and change … Read more
The singleton design pattern is one of the simplest yet most powerful design patterns in software engineering. If you’ve ever needed a single, globally accessible instance of a class, you’ve already touched the world of Singleton. Introduction to Singleton Design Pattern in C# The Singleton Pattern in C# ensures that a class has only one … Read more
