Web Development in C# (.NET): From Basics to Deployment

This book is your practical guide to the world of modern web development on the .NET platform using the C# language. You will journey from basic concepts to the full cycle of creating and deploying web applications. The author, Alexey Trofimov, a senior developer with 10 years of experience, has structured the material so that even a beginner can confidently start writing code from the very first chapters.

What the book is about

The book covers all key stages of web application development in C#:

• C# and .NET Basics: syntax, data types, OOP, exception handling, and collections.
• ASP.NET Core MVC: Model-View-Controller architecture, routing, controllers, views, and models.
• Working with Databases: Entity Framework Core, LINQ, migrations, table relationships.
• Creating REST API: endpoint design, serialization, authentication and authorization (JWT).
• Advanced Topics: dependency injection, middleware, background tasks, SignalR for real-time applications.
• Testing and Debugging: unit tests, integration testing, profiling.
• Deployment and DevOps: setting up CI/CD, publishing to Azure, Docker, IIS, and Linux (Nginx).

Who this book is for

• Beginner developers who want to learn C# and .NET from scratch and immediately apply their knowledge in practice.
• Backend developers in other languages (Java, Python, PHP) looking to transition to the Microsoft ecosystem.
• IT students and graduates preparing for real-world projects and job interviews.
• Freelancers and indie developers aiming to create full-fledged web applications and services.

What you will learn and be able to do after reading

• Write clean, maintainable C# code using modern patterns.
• Build web application architecture on ASP.NET Core with layer separation.
• Work with databases via Entity Framework Core — from simple queries to complex relationships.
• Create secure REST APIs with authentication and a role-based model.
• Set up automated testing and continuous integration.
• Deploy a finished application on cloud platforms and your own servers.

Each chapter contains practical examples, ready-made projects, and assignments for independent work. You won't just read theory — you will create a full-fledged web application (an online store) from the first line of code to deployment in production.

The book is written in a lively, clear language, without excessive academic formality. All examples are relevant for .NET 8 (LTS) and newer versions. This is an ideal choice for those who want to become a sought-after C# developer and work confidently in the Microsoft ecosystem.
