ASP.NET Core is a modern web development framework that provides a variety of built-in security features to help prevent attacks on web application. Here are a few ways we can use ASP.NET Core to prevent attacks: Introduction In today’s threat landscape, web application security is no longer optional, it’s essential. ASP.NET Core provides a robust security framework with built-in features to defend against common attack vectors. This guide explores practical implementations of these security measures to protect your applications effectively. ...

Introduction If you’ve spent any time building C# applications, you’ve probably run into situations where you need to decide whether your objects should be changeable or locked down after creation. This choice between mutability and immutability isn’t just academic, it can significantly impact how your code behaves, how easy it is to debug, and even how it performs. In this post, I’ll walk you through both approaches and help you figure out which one makes sense for your specific coding challenges. ...

What’s the Deal with Lambda Expressions? If you’ve been coding in C# for a while, you’ve probably seen that funny arrow => sprinkled throughout code. That’s a lambda expression, basically a shortcut for writing tiny methods on the fly without all the ceremony of creating a named method. Think of lambdas as little function snippets that you can pass around like any other variable. They showed up in C# 3.0 and have been making our lives easier ever since. ...

So What’s an Abstract Class Anyway? Think of an abstract class as a half-finished blueprint. You can’t build directly from it, but it gives any derived classes a head start with some pre-defined structure and behavior. It’s like a parent saying, “Here’s how our family does some things, but you’ll need to figure out these other parts yourself.” Abstract classes sit right in the sweet spot between interfaces (all talk, no action) and concrete classes (fully ready to use). They’re perfect when you want to share code but still enforce certain implementation requirements. ...

What is a Deadlock? If you’ve ever worked on multithreaded applications in C#, you’ve likely encountered or at least heard about deadlocks. A deadlock is one of the most frustrating concurrency issues that can bring your application to a complete standstill. Simply put, a deadlock occurs when two or more threads become permanently blocked, waiting for each other to release resources. Imagine two people approaching a narrow doorway from opposite sides, each politely waiting for the other to go first – neither moves, and both remain stuck. ...

If you’ve been coding in C# for a while, you’ve probably heard about boxing and unboxing. These concepts deal with how C# handles conversions between value types and reference types, and they can significantly impact your application’s performance. What’s the Difference Between Value and Reference Types? In C#, value types (like int, float, struct) live on the stack, while reference types (like string, object, classes) live on the heap. This distinction matters for performance and memory management. ...
