    Study Notes

    Overview of C#

    • C# (pronounced "C sharp") is a modern, object-oriented programming language developed by Microsoft.
    • It is part of the .NET framework and is used to build a wide range of applications, including web, mobile, and desktop.

    Key Features

    • Object-Oriented: Supports encapsulation, inheritance, and polymorphism.
    • Strongly Typed: Requires explicit declarations, reducing errors at runtime.
    • Garbage Collection: Automatically manages memory allocation and deallocation.
    • Interoperability: Can work with other languages and technologies within the .NET framework.
    • Asynchronous Programming: Supports async and await keywords for handling asynchronous operations.

    Syntax Basics

    • Variables: Declared using types (e.g., int, string, bool).
      • Example: int count = 10;
    • Control Structures: Includes if, else, switch, for, while, and foreach.
    • Methods: Functions defined within classes, can be static or instance methods.
      • Example:
        public void Display() {
            Console.WriteLine("Hello, World!");
        }
        

    Object-Oriented Concepts

    • Classes and Objects: Classes are blueprints for creating objects (instances).
    • Inheritance: Allows a class to inherit methods and properties from another class.
    • Interfaces: Define a contract that implementing classes must fulfill.
    • Polymorphism: Allows methods to be used interchangeably with different object types.

    Common Libraries and Tools

    • .NET Framework: Provides a comprehensive library for various applications.
    • ASP.NET: Framework for building web applications and services.
    • Entity Framework: ORM (Object-Relational Mapping) tool for database interactions.
    • Visual Studio: Primary IDE for developing C# applications, with features like IntelliSense and debugging.

    Common Use Cases

    • Web applications using ASP.NET
    • Desktop applications using Windows Forms or WPF
    • Game development with Unity
    • Cloud-based applications with Azure services

    Best Practices

    • Follow naming conventions: PascalCase for classes, camelCase for methods and variables.
    • Utilize exception handling (try, catch, finally) to manage errors gracefully.
    • Write unit tests to ensure code reliability and maintainability.
    • Keep methods short and focused on a single task (Single Responsibility Principle).

    Development Environment

    • Install the .NET SDK for compiling and running C# applications.
    • Use integrated development environments (IDEs) like Visual Studio or Visual Studio Code for improved productivity.
