Back to Roadmap
Stage Main Topic Content & Learning Activities Objectives & Deliverables
1 Introduction & Setup
  • Learn about the C# language and the .NET platform.
  • Install Visual Studio or the .NET SDK.
  • Write and run your first "Hello, World!" program.
  • Understand what C# is and its role.
  • Successfully set up the programming environment.
2 Basic Syntax & Variables
  • Learn the basic structure of a C# program.
  • Declare and use variables and constants.
  • Get familiar with data types (int, string, bool, etc.).
  • Practice inputting and outputting data to the console.
  • Be able to write simple programs that use variables.
  • Understand how to store different types of data.
3 Operators and Expressions
  • Use arithmetic operators (+, -, *, /).
  • Perform comparisons (==, !=, >, <).
  • Combine conditions with logical operators (&&, ||, !).
  • Perform calculations and comparisons in C#.
  • Write complex logical expressions.
4 Control Flow
  • Branch logic with if-else and switch-case statements.
  • Perform iteration with for, while, and do-while loops.
  • Control the execution flow of the program.
  • Write programs with more complex logic.
5 Methods
  • Organize code into reusable logical blocks.
  • Pass data to methods via parameters.
  • Receive return values from methods.
  • Write more structured and maintainable code.
6 Arrays and Strings
  • Store and process a collection of data of the same type with arrays.
  • Perform common string operations (concatenation, slicing, searching).
  • Work with collections of data.
  • Process text.
7 Classes and Objects (Overview)
  • Understand the basic concepts of Object-Oriented Programming (OOP).
  • Define a class and create an object.
  • Start thinking in an object-oriented way.
8 Basic Data Structures
  • Use List to manage dynamic lists.
  • Use Dictionary to store key-value data.
  • Choose the appropriate data structure for the problem.
9 Exception Handling
  • Handle potential errors in the program with try-catch.
  • Ensure code execution regardless of errors with finally.
  • Write robust programs that can handle errors.
10 Introduction to LINQ
  • Learn about Language Integrated Query (LINQ).
  • Perform simple data queries on collections.
  • Write more concise and readable data query code.
11 Small Consolidation Project
  • Apply all learned knowledge to build a complete console application.
  • Suggestions: Contact manager, simple calculator, number guessing game.
  • Consolidate knowledge and have a first practical product.

Core Mindsets for C# Programming

1. Problem-Solve First, Code Second

Before writing a single line of code, break down the problem on paper or a whiteboard. A clear plan makes for cleaner, more effective code.

2. Start Small, Iterate Often

Don't try to build the entire application at once. Get a small piece working, test it, and then build on top of it. This makes debugging easier and provides constant progress.

3. Embrace the Debugger

The debugger is your best friend. Learn to use breakpoints and step through your code to understand what it's *actually* doing, not what you *think* it's doing.

4. Read Code as Much as You Write It

Explore open-source projects and read code from experienced developers. This is one of the fastest ways to learn new patterns, styles, and best practices in the C# ecosystem.
