Description

Many developers entering the .NET ecosystem — especially those coming from other languages — struggle to understand large existing codebases. It’s hard to figure out how components relate, how layers interact, and what role design patterns, principles, and frameworks play in a real application.

This course is designed to bridge that gap.

In this hands-on training, you'll build a complete turn-based RPG game, evolving it from a simple console application into a modular, testable system with a Web API and a modern Blazor UI. Along the way, you’ll apply professional practices like object-oriented design, SOLID principles, layered architecture, dependency injection, domain modeling, and unit testing.

The goal is not to teach each of these technologies or patterns in depth — but to give you a working introduction to how they fit together in a real application. By building it yourself, you'll develop a clear understanding of what each piece does, why it exists, and how it connects with the rest.

By the end of this course, you will be able to look at an enterprise .NET solution and understand the big picture: where the business logic lives, how the application is structured, and how best practices are applied to keep the system maintainable and scalable.
