When you have multiple applications and they need to communicate with each other to exchange data you might want to use a protocol that makes something like that happen. In C#, the HTTPClient class provides a powerful and flexible way to make HTTP requests and handle responses. Whether you’re building a web application that needs to interact with APIs or simply need to retrieve data from a server, HTTPClient in...

Attributes and decorators, which allow you to attach metadata to classes, properties, and methods. Attributes Attributes in C# allow you to attach metadata to your classes, methods, and other code elements. This metadata can then be used at runtime to modify the behavior of your code. Attributes are applied to code elements using square brackets, and they can contain additional information such as parameters. For example, you can use the [Serializable] attribute to...

Introduction Performance optimization is a key concern in software development, regardless of the programming language or platform you’re using. It’s all about making your software run faster or with less memory consumption, leading to better user experience and more efficient resource usage. For .NET developers, understanding and implementing performance optimization strategies can be the difference between an application that just ‘works’ and an application that works exceptionally well, even under heavy load. //...

In this section, we’ll walk through the basics of regular expressions, their syntax, and key elements to help you...

I’d like to take you on a journey back in time, precisely 15 years ago, when my journey into software development began. As a younger me, armed with nothing but curiosity, I was introduced to the html and css. In the beginning, it was all about figuring out the basics. HTML websites were my training ground. Then came PHP, followed by JavaScript. Every new language was like a puzzle. This wasn’t...

Mastering the art of scalable and resilient systems with essential microservices design patterns Unleash the power of microservices Are you striving to build efficient, scalable, and resilient software systems? As a software developer or senior developer, you must have come across the term “microservices architecture.” This revolutionary approach to software development has been adopted by many successful tech giants, such as Netflix, Amazon, and Spotify. But, what exactly are microservices, and why...

In this section, we’ll explore the world of unit testing in C# and .NET, learn what unit testing is, why it’s important, and the landscape of testing frameworks and tools available to developers. What is Unit Testing? Unit testing is the process of verifying the correctness of individual units of code, typically methods or functions, in isolation from the rest of the system. This ensures that each unit performs as expected and...

Cyclomatic complexity is a code metric (integer value 1 or more) used to measure how complex a function/method is. It does not take into account lines of code but instead considers complexity to be the distinct paths through a function. Microsoft defines cyclomatic complexity as measuring the amount of decision logic in a source code function. Cyclomatic complexity: if if if if if else … Because cyclomatic complexity concerns itself with decision branches through...

LINQ (Language Integrated Query) is a powerful querying tool in .NET that allows you to perform complex queries directly in C#. The System.Linq.Expressions namespace is a part of LINQ that provides classes, interfaces, enumerations and structures to work with lambda expressions and expression trees. Lambda expressions are a way to create anonymous methods inline where they’re used, usually with the purpose of manipulating data. For example, let’s say you have a list...

Understanding uow to use And and Or operators with Expression Trees As a C# developer, you may have come across scenarios where you need to build complex logical expressions dynamically based on user input or other dynamic factors. In such cases, building expressions statically can become tedious and error-prone. In this article, we’ll explore how to use expression trees to build logical expressions in C#. We’ll start with a simple example that...

Maximizing Performance in Asynchronous Programming Task and Task<TResult> The Task and Task<TResult> types were introduced in .NET 4.0 as part of the Task Parallel Library (TPL) in 2010, which provided a new model for writing multithreaded and asynchronous code. For demonstration purposes, let’s build an example: using System; using System.Diagnostics; using System.Threading.Tasks; public class Program {     public static void Main()     {         long limit = 2;         var stopwatch = new Stopwatch();         Console.WriteLine("Press 'C' key to exit the loop...");         while...

What is Kafka? Kafka is a distributed streaming platform developed by the Apache Software Foundation. It is designed to handle high-volume, real-time data streams and is commonly used for building data pipelines, stream processing applications, and real-time analytics. At its core, Kafka is a publish-subscribe messaging system that allows producers to write data to topics and consumers to read data from those topics in real-time. Kafka is highly scalable and fault-tolerant, with...

Introduction to Async and Await in C# Asynchronous programming has come a long way in C#. Prior to the introduction of async and await, developers had to rely on callbacks, events and other techniques like the BeginXXX/EndXXX pattern or BackgroundWorker. These methods often led to complex and difficult-to-maintain code. With the release of C# 5.0, async and await keywords were introduced, simplifying asynchronous programming and making it more accessible to developers. The Importance...
