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...

Introduction One common way to speed up our applications is by introducing a cache. Typically, the first option that comes to mind is using a MemoryCache (RAM) to save some data in order to speed up retrieval. This approach works well for monolithic applications. However, in the case of microservice...

Performance comparison between LinkedList and ToArray Some weeks ago I created an article comparing the performance of ToList versus ToArray when creating short lived collections that won’t be mutated, usually used to prevent multiple enumerations when iterating over a temporary LINQ transformation or to ensure mapping exceptions will be thrown...

At some point in our careers, many of us have found ourselves working on a project that requires performance tuning The need to write high performance .NET code should come from performance issues or business needs. Today, we’ll take a look at just a few of the ways we can...

AntiPattern Problem Object-oriented analysis and design (OOA&D) models are often presented without clarifying the viewpoint represented by the model. By default, OOA&D models denote an implementation viewpoint that is potentially the least useful. Mixed viewpoints don't allow the fundamental separation of interfaces from implementation details, which are one of the...

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...

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....

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;...

Developing a robust, scalable, and efficient system can be daunting. However, understanding the key concepts and components can make the process more manageable. In this blog post, we’ll explore essential system design components such as DNS, load balancing, API Gateway, and more, along with a concise cheat sheet that...

Confused about choosing between struct and class in C#? Read this article to understand the differences and make an informed decision. In C#, there are two primary object types that developers can use to build their code: structs and classes. While these two types may seem similar at first glance,...

Unit testing is one of the major parts of software testing which can be handled by the developer itself. It is used to test the smallest components of your code. The purpose of the Unit test is to validate the functionality or expected output of your code during your development...

New and old ways of creating your own exceptions in dotnet with C# 11 and .NET 7. Let’s talk about building custom exceptions in C# code and why you’d want to do that. We’ll cover the traditional way as well as a newer way you might want to do this...

Sometimes we have to perform several queries to the database, put the results into memory, and then process them as needed. For example, we have a Supplier table and a Customer table. Both tables have a substantial amount of data. We want to combine existing Supplier and Customer data...

Sometimes it’s the little things that count. When .NET 6 dropped this November, a few top-line items grabbed all the attention. I’m talking about C# 10, hot reload, Blazor’s AOT compilation, and some serious inner loop performance improvements. All of them are worthy enhancements. But if you look beyond the...

Probably, one of the most dreaded software development methodologies might make sense again for small companies in a operational perspective. Ken Schwaber — the cofounder of Scrum and founder of Scrum.org — says Waterfall “literally ruined our profession.” “It made it so people were viewed as resources rather than valuable...

Hi everyone, this article include encrypting your database columns with EntityFramework. Your database providers can be MSSQL or PostgreSQL. Considering that some database columns contain confidential data, it is of great importance that the data is encrypted in case of capture of our database. In this article, it will...

Exceptions are part of any software and can happen any time even where we are absolutely sure that nothing can go wrong. Exceptions are inevitable, we all agree with that. We should always deal with them in our applications to avoid any kind of unrecoverable crash. In order to...

Microservices The term microservices portrays a software development style that has grown from contemporary trends to set up practices that are meant to increase the speed and efficiency of developing and managing software solutions at scale. Microservices is more about applying a certain number of principles and architectural patterns as...

We’ll learn about the use of SignalR to build real-time functionality in your ASP.NET Core web apps. SignalR can also be used to add real-time functionality to desktop applications, mobile apps and Azure Functions. What is SignalR? SignalR has been around for 5+ years now, allowing ASP .NET developers to...

This article provides an introduction and conceptual background to working with .NET on Docker. Docker: Packaging your apps to deploy and run anywhere   Docker is an open platform that enables developers and administrators to build images, ship, and run distributed applications in a loosely isolated environment called a container....
