Learn C# for Unity from beginner to advanced in 2026 — MonoBehaviour lifecycle, coroutines, async, performance and DOTS. Start building games today. If you want to build games in 2026, learning C# for Unity is still the single highest-leverage skill you can pick up. Unity ships with C# as its only first-class scripting language, and the version of C# you write inside the editor today is a modern, fast, fully-featured language — not the cut-down dialect people remember from a decade ago. This guide walks you from your very first MonoBehaviour to advanced topics like the Job System, object pooling and allocation-free game loops, with runnable code you can paste straight into a project. Why C# for Unity Is Different From "Normal" C# Everything you know about .NET still applies — LINQ, generics, async , pattern matching, records. But Unity adds a layer on top that trips up almost every newcomer, and understanding it early will save you weeks. You don't own the ...

Learn API security best practices for 2026 with runnable C# and ASP.NET Core examples — JWT, rate limiting, BOLA fixes. Start hardening your REST API today. If you ship a REST API in 2026, you are running a public attack surface. Attackers no longer bother with your UI — they read your OpenAPI document, enumerate your endpoints, and hammer them directly. This guide covers the API security best practices that actually matter today, with runnable C# and ASP.NET Core examples you can drop into a real project. We will focus on the failures that show up in genuine breach reports: broken object-level authorization, weak token validation, missing rate limits, and secrets sitting in source control. Every example targets ASP.NET Core on .NET 8 or later, and each one explains why the control exists — because a security rule you do not understand is a security rule you will disable the first time it breaks a deployment. Why REST API Security Fails: The OWASP API Security Top 10 The OW...

Learn Serilog structured logging in .NET with runnable C# examples, sinks, enrichers, and production best practices. Start logging smarter today. If you have ever opened a 400 MB text log file at 2 a.m. trying to figure out why one customer's checkout failed, you already understand why Serilog .NET exists. Traditional logging writes sentences. Serilog writes data. That single difference — structured logging instead of string concatenation — is what turns your logs from a wall of text into a queryable database of everything your application did in production. In this tutorial you will learn how to set up Serilog in a .NET 8/9 application, configure sinks and enrichers, use scopes and correlation IDs, and apply the production best practices that separate a hobby project from a system you can actually operate. Every example is runnable. What Is Structured Logging (and Why String Logs Fail) Consider the classic approach: // The old way — information is destroyed at write ti...

Learn Azure Cosmos DB with C# in this step-by-step tutorial. Master partition keys, RUs, LINQ queries, and .NET SDK best practices. Start building today! If you have ever watched a SQL Server database buckle under traffic from three continents at once, you already understand why Azure Cosmos DB exists. Working with Azure Cosmos DB C# applications gives you a globally distributed, multi-model database with single-digit millisecond reads, 99.999% availability, and elastic scale — all reachable through a first-class .NET SDK. This tutorial walks you through everything from your first container to advanced patterns like bulk ingestion, optimistic concurrency, and change feed processing. We will use the Microsoft.Azure.Cosmos v3 SDK on .NET 8/9, and every example is runnable. More importantly, we will explain why each decision matters — because in Cosmos DB, an innocent-looking design choice can multiply your monthly bill by ten. What Is Azure Cosmos DB and Why Should C# Develop...

Learn Git best practices for .NET teams — branching strategies, clean commits, and pull request reviews that scale. Start shipping safer C# code today. Most .NET teams don't lose time to hard algorithms. They lose it to a 4,000-line pull request nobody wants to review, a develop branch that hasn't been merged in three weeks, and a merge conflict in a .csproj file that silently drops a package reference. Adopting solid git best practices fixes more delivery problems than any refactor, because it changes how your team integrates work rather than how one developer writes it. This guide covers the Git workflow decisions that matter specifically for C# and .NET teams: which branching strategy to pick, how to write commits that survive a production incident, how to keep pull requests reviewable, and the .NET-specific pitfalls (solution files, generated code, secrets in appsettings.json ) that generic Git tutorials never mention. Why Git Best Practices Matter More in .NET C...

Learn GitHub Actions CI/CD for .NET with a complete YAML workflow to build, test and deploy your app to Azure. Copy the pipeline and ship today. If you are still clicking "Publish" from Visual Studio to get your API into production, you are one tired Friday away from an outage. GitHub Actions .NET pipelines solve that problem: every push builds your solution, runs your tests, and — when the tests pass — ships the artifact to Azure, AWS, or your own server, without a human touching a button. In this tutorial you will build a complete GitHub Actions CI/CD workflow for a .NET 10 application from an empty YAML file to a production deployment with environment approvals, and you will understand why each block exists rather than just copying it. Everything below is runnable. You will need a GitHub repository, a .NET solution with at least one test project, and (for the deployment half) an Azure App Service or any host that accepts a zip deploy. Why GitHub Actions for a .NET ...
