The way of calculating amount of memory occupied by some object in C# .NET. Introduction C#.NET is a high-level, multipurpose modern language with only two flaws compared to C++: generics and sizeof operator. Anyone who tried using generics in C# (coming from the C++ world) the same way as in...

Introduction Open Data Protocol (OData) is a standard protocol for building and consuming RESTful APIs. It extends traditional REST-based data access techniques by providing a uniform way to expose, structure, and manipulate data. Originally developed by Microsoft, OData is widely adopted because it standardizes queries and interoperability between different systems...

I have written a few tutorials on Entity Framework already, but I’ve always used SQL Server. The reason is simple: It’s easy to use. Then I got a few questions and requests on how to use SQLite with entity framework in a C# project. In this tutorial, I am going...

SOLID principles make it easy for a developer to write easily extendable code and avoid common coding errors. These principles were introduced by Robert C. Martin, and they have become a fundamental part of object-oriented programming. In the context of .NET development, adhering to SOLID principles can lead to more...

In this article, we will explore the different categories of C# data types. We will take an in-depth look into the distinctions between value types and reference types, understanding their nature and behaviors when instantiated, compared, or assigned. Value types In C#, there are two main categories of data types:...

In software development, writing clean, maintainable code is crucial for the long-term success of any project. However, even experienced developers can inadvertently introduce “code smells” — subtle indicators that something may be wrong with your code.   In C#, these code smells can manifest as long methods, large classes, or...

Intro What is the Result pattern? Basically it is a great way to write error-tolerant code that can be composed. Do you feel that phrase sounds familiar? If you like F# you are right, I’ve taken it from the Results documentation. The thing is functional languages have been using this...

In this article you will learn how to map objects in .NET using various techniques and libraries. We’ll explore what is the best way to map objects in .NET in 2024. What is object mapping What is object mapping and why do you need one in ASP.NET Core applications? Object...

This is a behavioral pattern where the main goal is to split a complex job into multiple steps, each with a specific functionality. It’s really good for several types of architectures. For a system composed of various microservices with numerous components, this is a way to keep things easier to...

C# is a powerful programming language, widely used for software development across various domains. One crucial aspect of application development is dealing with PDFs, whether it's generating PDFs, extracting information from existing PDF documents, or manipulating PDF files. In this article, we'll explore five C# PDF generating libraries that every...

Are you preparing for an interview that will involve C# asynchronous programming? You’ve come to the right place! This comprehensive article covers a wide range of C# async-await interview questions that will test your understanding of the async-await pattern, along with solutions and examples to help you sharpen your skills....

Introduction Caching is a technique used to store frequently accessed data in a fast-access storage layer to improve application performance and reduce the load on backend systems. By serving data from the cache, we can avoid expensive database queries or API calls, resulting in faster response times and improved scalability....

Dependency injection is a powerful technique in software development that promotes loose coupling between components and improves testability and maintainability. When working with the HttpClient library in C#, integrating it with dependency injection can lead to cleaner and more manageable code. In this article, we will explore how to use...

Creating background services in .NET Core is a powerful way to perform long-running, background tasks that are independent of user interaction. These tasks can range from data processing, sending batch emails, to file I/O operations — all critical for today’s complex application ecosystems. This guide delves deep into the architecture,...

LINQ (Language Integrated Query) has revolutionized the way we interact with data in C#. It offers a consistent, readable, and concise way to manipulate collections, databases, XML, and more. However, the beauty and ease of LINQ can sometimes mask performance pitfalls. Understanding LINQ’s underpinnings Before we jump into optimizations, it’s...

In software engineering, composition plays an important role in object-oriented programming. If you’ve come across other articles or videos I’ve put out about object-oriented programming, you’ll know that I try to push composition over inheritance as much as I can. This is strictly because I have seen overuse of inheritance...

The Deadlock Dilemma 🔒 In the world of multithreaded programming, deadlocks lurk like silent assassins, waiting to strike when you least expect it. A deadlock occurs when two or more threads become entangled in a vicious cycle, each holding a resource that the other needs, resulting in a perpetual stalemate....

Introduction Delegates are a fundamental concept in C# that allow you to treat methods as objects. They provide a way to define a type that represents a reference to a method, enabling you to encapsulate and pass around methods as parameters, store them in variables, and invoke them whenever needed....

Imagine crafting a library app where users effortlessly find books by title, author, or genre. Traditional search methods drown you in code. But fear not! Dynamic Querying in C# saves the day. In our tale, crafting separate search methods for each book attribute becomes a headache. The code becomes a...

Pagination is in front of us everyday yet we take it for granted kind of like we do with most things. It’s what chunks huge lists of data (blog posts, articles, products) into pages so we can navigate through data. This is how you did pagination until this point. using...
