Learn C# delegates, events, and Func/Action with practical examples. Master event-driven programming in C# the right way — start coding today! If you've ever wondered how a button "knows" when it's clicked, or how one part of your application can notify another without being tightly coupled to it, the answer is C# delegates . Delegates, events, and the built-in Func and Action types form the backbone of event-driven programming in .NET. They power everything from UI frameworks like WPF and ASP.NET Core to LINQ, async callbacks, and the observer pattern. In this complete guide, you'll learn exactly what C# delegates are, how they relate to events and the Func / Action family, and—most importantly— why they exist. We'll cover practical, runnable code examples, best practices, and the common pitfalls that trip up beginners and intermediates alike. Whether you're searching for a simple C# delegate example or trying to understand delegate vs e...

Learn how to use Docker with .NET 9 to containerize and deploy your ASP.NET Core app. Step-by-step tutorial with Dockerfile examples. Start building today! If you're building modern web APIs or web apps, learning how to use Docker with .NET 9 is one of the highest-leverage skills you can pick up in 2026. Containers let you package your ASP.NET Core application — code, runtime, and dependencies — into a single portable image that runs identically on your laptop, your teammate's machine, and production in the cloud. In this tutorial, you'll learn how to containerize an ASP.NET Core app from scratch, write an optimized Dockerfile, use Docker Compose for multi-container setups, and deploy with confidence. By the end, you'll understand not just how to dockerize ASP.NET Core, but why each step matters — including the performance and security trade-offs that separate a beginner image from a production-ready one. Why Use Docker with .NET 9? The phrase "it ...

In this tutorial, you'll learn exactly how to create a Minimal API in .NET 8, wire up dependency injection, return JSON, validate input, and follow the best practices that separate hobby projects from production-grade services. Whether you're a beginner searching for a Minimal API tutorial , an intermediate developer looking for best practices , or a senior engineer evaluating performance trade-offs, this guide covers it all with runnable examples. Wha...

Learn API versioning in ASP.NET Core with practical C# examples. Compare URL, header & query strategies, avoid pitfalls, and version your APIs the right way today. If you've ever shipped a public or internal REST API, you already know the hard truth: change is inevitable, but breaking your clients is optional . API versioning in ASP.NET Core is the discipline that lets you evolve endpoints, rename fields, and change response shapes without forcing every consumer to update on your timeline. In this complete guide, you'll learn the four main ASP.NET Core API versioning strategies, see runnable C# code for each, and discover the best practices and pitfalls that separate junior implementations from production-grade APIs. Whether you're a beginner searching for how to version a REST API in C# , an intermediate developer hunting for best practices, or a senior engineer designing an enterprise API governance model, this tutorial has you covered. Let's dive in. Wh...

Learn gRPC in .NET with Protocol Buffers to build fast, type-safe APIs. Step-by-step C# tutorial with code examples and best practices. Start building today! If you're building microservices or high-throughput APIs in 2026, gRPC .NET is one of the most powerful tools in the .NET ecosystem. Built on HTTP/2 and Protocol Buffers, gRPC delivers smaller payloads, faster serialization, and strongly-typed contracts that REST APIs simply can't match. In this gRPC C# tutorial, you'll learn how to build a high-performance gRPC service in ASP.NET Core from scratch, understand Protocol Buffers, and apply production-ready best practices. What Is gRPC in .NET and Why Should You Use It? gRPC (gRPC Remote Procedure Calls) is an open-source, contract-first RPC framework originally developed by Google. In the .NET world, Grpc.AspNetCore provides first-class, fully managed support. Instead of sending verbose JSON over HTTP/1.1, gRPC .NET serializes data using Protocol Buffers (proto...
