Introduction In a previous article, I wrote about How to Implement JWT Authentication in ASP.NET Core Minimal API, where I introduced the basic concept of JWT (JSON Web Tokens) and demonstrated how to implement authentication using the dotnet user-jwts tool. This approach provided a straightforward way to secure APIs during development by automatically handling token generation and validation. […]

Introduction Deploying new features in an application can be risky. A small mistake could lead to bugs, disrupt users, or even cause downtime. In today’s fast-paced development environment, developers need a way to enable or disable features without redeploying the entire application. This is where feature flags come in. Feature flags give developers control over […]

Introduction to Logging and Why It Matters in .NET Applications In modern software development, logging plays an essential role in monitoring, debugging, and maintaining applications. Logging is the process of recording events or messages from an application’s execution, which can provide critical insights for developers and administrators alike. Whether you’re building a small utility or […]

What exactly is Testcontainers? Testcontainers is an open-source library designed to make integration testing more manageable and reliable by using Docker containers to spin up “throwaway” instances of various services. It allows developers to create lightweight, temporary versions of databases, message brokers, web browsers, and more, using real infrastructure instead of mocks or in-memory simulators. […]

Introduction In a previous article, I wrote about How to Implement In-Memory Caching in .NET Console App Using C#, where I introduced the basic concept of caching and explained the difference between first-level (in-memory) and second-level (distributed) caching. In-memory caching is a powerful tool to boost application performance by storing frequently accessed data in memory, […]

What is a Cache and Why is it Important? A cache is a temporary storage area that holds frequently accessed data to improve performance. Instead of recalculating or fetching the same data repeatedly from a slower source (like a database or external API), the cache stores this data so it can be quickly retrieved. This […]

What is FluentAssertions? FluentAssertions is a library that provides a rich set of extension methods to assert the outcomes of .NET tests in a more expressive and readable way. By using FluentAssertions, you can write unit tests in a fluent, human-readable style, making it easier to specify the expected behavior of your code. This approach […]
