Interfaces are at the heart of the “composition-over-inheritance” paradigm — let’s see what that means! As you probably know, C# is a statically typed language. And as such, it is very helpful with type-checking and safe data conversions. Your IDE most likely knows when you’re feeding a variable of the...

Introduction In the realm of software development, the complexity of applications has steadily increased over time. To tackle this challenge, software architects have continuously evolved their approaches to designing and structuring backend systems. In this article, we will delve into the evolution of backend software architecture, focusing on key...

In today’s rapidly evolving web development landscape, selecting the right framework is crucial for delivering efficient, scalable, and maintainable applications. React and Blazor are two leading frameworks that have gained significant attention in recent years. As developers and businesses weigh their options, understanding the differences between these two powerful...

When crafting elegant and scalable software in C#, a keen understanding of Dependency Injection (DI) is more than a luxury — it’s a necessity. It’s a design pattern that underpins many modern .NET applications, providing a solid foundation for managing dependencies between classes. In its most basic form, Dependency...

In a situation where we need to modify our API’s structure or functionality while ensuring that existing API clients remain unaffected, the solution is versioning. We can designate our current APIs as the older version and introduce all intended changes in the next (or latest) version. This approach resolves...

MSSQL and MySQL are two of the most popular relational database management systems in the world Nowadays, even when businesses are selling comparable products, rivalry between them is fairly widespread. In a market where there is competition, a company’s profitability is influenced by its ability to offer the finest...

To write files with C#, you have to know how to do it. The basics aren’t rocket science. There are a few lines of code you need to know. But writing and reading files with C# is something every beginning C# developer should be able to do. If you...

Simplifying Data Transport in C#. In modern C# development, data transport objects (DTOs) play a crucial role in exchanging information between different layers of an application, such as between a client and a server, and traditionally, developers have used classes to define DTOs, which involves writing boilerplate code for properties,...

C# Data Structures Handbook! Every decision in programming is a silent influencer of performance and clarity. In C#, one such vital choice is selecting the right data structure. Data structures are foundational pillars. These structures are where data lives, breathes, and interacts, determining the efficiency and readability of our code....

What does your performance “stack” look like? There are all kinds of tools available for measuring page speed, but what data and assumptions do they use to measure performance? And speaking of measuring performance, there’s quite a difference between that and monitoring performance. Geoff Graham evaluates the data of...

Whether you have an app with just a few users or millions of users per day, like Agoda, improving the user experience by optimizing application performance is always crucial. In the case of very high-traffic websites in the cloud, this optimization can translate into significant cost savings by reducing...

Web scraping is a technique that scrapes information from other online sources. This is a great way to combine different sources into one source. To create a web scraper you need a few things: online sources, some code that can access the internet, and a GUI. In this article,...

Unleashing the Power of Meta-Programming: A Comprehensive Guide to C# Reflection Reflection, put simply, is a mechanism provided by the .NET framework that allows a running program to examine and manipulate itself. It’s like a coding mirror that gives your application the ability to look at its own structure, inspect...

Bending the Clean Architecture Principles Async await meme Introduction Imagine you’re a chef in a kitchen full of ingredients, some fresh, some a bit past their prime, all thanks to Microsoft’s “We never throw anything away” policy. This is what programming asynchronously in C# is like — an overwhelming mix...

Small changes, Big wins: How little tweaks make your code easy on the eye When we think of clean code, our brain jumps to SOLID principles, short classes, no comments, and good design patterns. While all of those apply, they are useless without the simplest thing of all: good naming....

We have been living in a distributed world for quite some time, and when considering how should you implement the communication between any two parties involved, the discussion seems to gravitate around two options: API or messaging. Instead of focusing on the lost battle of which one is better,...

Unlocking Resilience and Transient-fault-handling in your C# Code In an ideal world, every operation we execute, every API we call, and every database we query, would always work flawlessly. Unfortunately, we live in a world where network outages, server overloads, and unexpected exceptions are common realities. To maintain robust, resilient...

I wrote a few articles about design patterns. A few examples are the Repository Pattern (or the generic version) and the Strategy Pattern. Both are very effective when writing software. But I have also mentioned SOLID, which is a collection of design principles. But what is the difference between...

Exploring Key Features, Use Cases, and Performance of Two Popular Real-time Communication Protocols Introduction Real-time communication plays a crucial role in today’s connected world, powering applications such as IoT devices, web-based chat, gaming, and industrial automation. Choosing the right protocol to facilitate this communication is essential to ensure the smooth...
