What is dotnet-developer-roadmap?

This repository is a structured learning roadmap for developers who want to work with .NET, Microsoft's platform for building web applications, desktop software, and cloud services. The roadmap covers over 260 tools, libraries, frameworks, books, and concepts, and it is organized by seniority level so that beginners, mid-level developers, and senior developers each have a clear path to follow. The repository contains visual diagrams of the roadmap as image files and PDFs you can download. A full version maps out every topic in detail, and a minimalist version shows only the bare-minimum knowledge a junior developer needs to get started. The guide begins with the history and structure of the .NET ecosystem, explaining how the older Windows-only .NET Framework, the cross-platform .NET Core, and the current unified .NET (now at version 9) relate to each other. From there it branches into topics that a working .NET developer would encounter on the job: the C# programming language, web frameworks like ASP.NET Core, databases and the tools that connect code to them, testing approaches, logging, background task processing, caching, and deployment through containers and cloud platforms. Later sections cover performance tuning, security, observability (the practice of monitoring a running system), and AI integration. Each section lists specific technologies and provides links to documentation, books, videos, and blog posts. The author also sells a paid companion bundle with interview questions, design patterns, and a course, but the roadmap content in the repository itself is free to use. The project is intended to help developers figure out what to learn next rather than to chase whichever tool happens to be popular at a given moment. The full README is longer than what was shown.
