This article explains the KISS (Keep It Simple, Stupid) principle in C# through practical, real-world examples. You’ll learn how to identify and eliminate unnecessary complexity in your code, refactor over-engineered solutions into simple, maintainable designs, and combine KISS with DRY and SOLID principles to create robust applications. Whether you’re a junior developer looking to write…

Memory management in .NET is handled by the Garbage Collector (GC), which automatically reclaims memory used by objects that are no longer needed. However, there are scenarios where you might want to manually control garbage collection or prevent unnecessary cleanup. Two commonly misunderstood methods are: GC.Collect() → Forces garbage collection. GC.SuppressFinalize() → Prevents the finalizer…

The core of ASP.NET Core is Kestrel, a lightweight, cross-platform web server designed for contemporary cloud-native applications. Kestrel powers your app in the background, regardless of whether you’re deploying it on Windows, Linux, or Docker. Let’s examine Kestrel’s definition, internal operation, deployment and configuration (using IIS or Nginx reverse proxy settings), and concluding with important…

1. Overview & Approach Security testing for ASP.NET Core should include multiple layers: Static Analysis (SAST): scan code for insecure patterns. Dependency/Package Scanning: find vulnerable NuGet packages. Configuration Review: Ensure framework and middleware settings are secure. Dynamic Testing (DAST): exercise the running app to find runtime flaws. Automated Integration Tests: programmatic tests that assert security…

Overview An Object-Relational Mapper (ORM) is frequently used by developers to link their code to the database while working with.NET applications. Entity Framework (EF) is the most widely used ORM in the.NET ecosystem. Since EF has changed over time, there are currently two primary versions: Entity Framework Core (EF Core) and Entity Framework 6 (EF6)….

Dependency injection (DI) plays a key role in managing object lifetimes and dependencies in contemporary.NET applications, particularly in ASP.NET Core and background services. Singleton and transient services are simple to comprehend, but scoped services—particularly those that are not part of the request pipeline—become more complex. This is where IServiceScopeFactory becomes crucial. This article breaks down….

Patterns at a glance SQL Server Query Notifications with SqlDependency Version-Stamp (Polling-Light) Strategy Event-Driven Invalidation (App-layer) Distributed Cache + Redis Pub/Sub Drop-in C# Cache Wrapper Best practices & pitfalls Why…

HTTP status codes are essential signals delivered from a server to a client (such a browser or mobile app) to indicate the result of a request in the context of web development and API integration. Status codes facilitate effective communication between developers and systems, regardless of whether a request was successful, unsuccessful due to an…

One essential software testing method is static testing, which looks at a program and its documentation without running the code. Static testing is different from dynamic testing, which involves running the software to find errors. Static testing, on the other hand, uses reviews and analysis to find defects early on. Static testing is included in…
