What skills does a .NET developer need?
It's one language, C#, spread across several very different application types
Every .NET developer starts with C# and a working understanding of the .NET platform itself — the runtime, the class library, and how NuGet packages and project files fit together. From there, data access (usually via Entity Framework Core) is close to universal, since almost every real application talks to a database.
What comes next depends on what you're building: ASP.NET Core for web apps and APIs, WPF, WinForms, or .NET MAUI for desktop and cross-platform apps, or Worker Services and Azure Functions for background and serverless workloads. Most of these converge on the same underlying skills — dependency injection, testing, and clean architecture.
Production-ready .NET developers round this out with logging, caching, and resilience patterns, and increasingly need to be comfortable with Docker, CI/CD, and Azure (or another cloud) to actually deploy and operate what they build.
The .NET Developer Roadmap
Work through the shared foundation first, then branch into the application type you're building
Programming Fundamentals & C#
The language every .NET application is written in, plus the tools you'll use daily.
The .NET Platform
What .NET actually is under the hood, and how projects and dependencies are organized.
Advanced C#
The language features that separate "knows C#" from "writes idiomatic C#."
Databases & Data Access
Almost every real .NET application needs to read and write persistent data.
Choosing Your Application Type
This is where paths diverge — pick the one that matches what you actually want to build.
Building APIs & Web Services
Expose data and functionality to clients, whether that's a browser, mobile app, or another service.
Dependency Injection & Application Architecture
Structure a codebase so it stays maintainable as it grows past a handful of files.
Testing
Prove the application behaves correctly before it reaches production.
Logging, Caching & Resilience
The production-grade concerns that turn a working app into a reliable one.
Containerization, CI/CD & Deployment
Package and ship .NET applications the way they're run in production.
Cloud & Ecosystem Tooling
Where most .NET applications actually run, and the tools that keep them healthy.
GitHub Projects
Real, buildable projects to put on your own GitHub
Layered CRUD Web App
Fork a clean-architecture ASP.NET Core starter and extend it with new entities and pages to practise EF Core, DI, and layered design together.
Cross-Platform Desktop/Mobile App
Build a small .NET MAUI app that runs on desktop and mobile from one codebase, to see MVVM and data binding outside the web stack.
Reference Microservices App
Study Microsoft's own reference app to see messaging, containerization, and .NET Aspire working together across multiple services.
Tested Minimal API
Spin up a Minimal API, add validation and auth, and cover it with xUnit and integration tests — a good rehearsal for a production-ready API.
Frequently Asked Questions
Common questions from people starting out as .NET developers
What's the difference between .NET and .NET Framework?
.NET Framework is the original, Windows-only version. Modern ".NET" (5 and later, unifying what used to be called .NET Core) is free, open source, and cross-platform, and is where all new development and Microsoft's investment goes. New projects should target modern .NET.
Is C# a good first programming language?
Yes — it's statically typed, which catches many mistakes early, has excellent tooling and error messages, and is used across web, desktop, mobile, and game development, so the fundamentals you learn transfer widely.
Should I learn ASP.NET Core or a desktop framework first?
It depends on your goal: web and API development (ASP.NET Core) has the most job openings and is the most common starting point, while WPF, WinForms, or .NET MAUI make sense if you specifically want to build desktop or mobile applications.
How does .NET compare to Java?
Both are mature, statically-typed, garbage-collected platforms with strong enterprise adoption, extensive libraries, and similar architectural patterns. The core difference is ecosystem: .NET runs on the CLR and centers on C#, while Java runs on the JVM and centers on Java or Kotlin.
Do I need to know Azure to be a .NET developer?
Not to start, but it's a strong asset. Because .NET is a Microsoft technology, many .NET jobs — especially at larger companies — expect at least basic familiarity with Azure App Service, Azure SQL, and CI/CD through Azure Pipelines or GitHub Actions.
How do I prepare for a .NET developer interview?
Be comfortable explaining async/await, dependency injection lifetimes, and value vs. reference types, know your way around EF Core migrations and LINQ, and have a project you can walk through — architecture, trade-offs, and how you tested it.
Track complete
From C# fundamentals to a tested, deployed application — that's the core of what employers expect from a .NET developer. Keep building, and let the application type you enjoy most — web, desktop, or cloud — pull you toward deeper specialization next.
