Hi DEV Community 👋
"We’ve all been there: you finish a tutorial, the code runs, but you still feel like you’re missing the 'why' behind the architecture. I started this repo because I realized that knowing syntax isn't the same as being a Software Engineer."
I am building an open-source repository for developers who want to grow stronger in their .NET Core Developer career path.
.NET Developer Career Path
Purpose
This wiki helps a .NET developers focusing on C#, ASP.NET Core, REST APIs, CQRS, Domain-Driven Design, clean architecture, Azure, DevOps, Docker, Kubernetes, testing, and code quality.
The content is written for practical interview preparation. Each page explains one concept, breaks down the core ideas with examples, explains why it matters, adds practical notes, provides interview questions with direct answers and examples, includes a realistic backend example when useful, and finishes with a real-world scenario, common mistakes, and a checklist.
Who This Wiki Is For
- .NET developers with around 3+ years of experience.
- Backend developers preparing for technical interviews in English.
- Candidates who need to explain architecture, API, Azure, DevOps, and testing decisions clearly.
- Developers who want realistic business examples rather than toy examples.
Recommended Study Path
- Start with C# fundamentals, dependency injection, async and await, exception handling, and nullable reference types.
- Move to ASP.NET Core…
The real goal is to build a practical knowledge base that helps developers strengthen their foundation, improve their skills, and become more confident as .NET Software Engineers.

Why I Started This Project
When learning .NET, it is easy to find many tutorials, videos, and blog posts. But after some time, many developers still ask themselves:
- Do I really understand the fundamentals?
- Do I know how to apply these concepts in real projects?
- Am I writing code in a clean and maintainable way?
- What level am I currently at as a .NET Software Engineer?
I wanted to create a structured place where developers can review, practice, and improve their knowledge step by step. This project is not only about knowing the answer to a question—it is about understanding the reason behind the answer.
The Core Philosophy
A strong developer career starts with a strong foundation. When the foundation is weak, every new topic feels difficult. When the foundation is strong, learning advanced topics like System Design or Cloud Architecture becomes much easier.
What This Knowledge Base Covers
This project is designed to help developers build a strong foundation in these critical areas:
- Fundamentals: C#, .NET, and ASP.NET Core internals.
- Architecture: SOLID, Clean Architecture, DDD, and CQRS.
- Data & Cloud: Entity Framework Core, SQL, and Azure Services.
- Modern Tooling: Docker, Kubernetes, and DevOps basics.
- Quality: Testing strategies and System Design thinking.
Beyond the Interview
This is important: while this project is useful when preparing for technical discussions or job changes, it is not only for interviews.
It is for everyday growth. In real projects, we need more than syntax; we need judgment.
We need to know:
- When to use a pattern and when it's "over-engineering."
- How to design maintainable APIs that don't break.
- How to communicate technical ideas clearly with teammates.
Who This Is For
This project is a living roadmap for:
- Junior .NET developers looking for a clear learning direction.
- Mid-level developers who want to review and strengthen their foundation.
- Engineers moving toward senior-level responsibilities.
- Backend developers who want to improve architecture and communication skills.
How You Can Help
I would love help from the community to improve this knowledge base. Small contributions make a huge difference!
Example contribution ideas:
- Explain a design pattern with a real-world .NET scenario.
- Add common mistakes when using Entity Framework Core.
- Share your own experience or "lessons learned" in a specific area.
- Improve existing explanations for clarity and grammar.

Let's Discuss
My hope is that this repository can become a community-driven knowledge base for the .NET ecosystem.
I’m curious: what was the hardest "senior-level" concept for you to grasp when you were starting out with .NET? For me, it was understanding the nuances of Dependency Injection lifetimes in large-scale apps. Let me know in the comments!
