Programming Languages Documentation

Explore the rich set of programming languages supported by Microsoft's development platforms. Dive deep into syntax, features, and best practices.

C# (C Sharp)

C# is a modern, object-oriented, and type-safe programming language developed by Microsoft. It's widely used for building a variety of applications, from Windows desktop applications to web services and games.

Key Features

  • Object-Oriented Programming
  • Type Safety and Memory Management
  • Asynchronous Programming (async/await)
  • LINQ (Language Integrated Query)
  • Generics

Getting Started

Learn the fundamentals of C# with our comprehensive guides.

// A simple C# "Hello, World!" program using System; public class HelloWorld { public static void Main(string[] args) { Console.WriteLine("Hello, World!"); } }

Tip:

Explore the latest C# features in .NET 6 and beyond.

VB.NET (Visual Basic .NET)

Visual Basic .NET is another powerful, object-oriented language from Microsoft, known for its ease of use and rapid application development capabilities, especially in the Windows environment.

Key Features

  • Simplified Syntax
  • Strongly Typed
  • Event-Driven Programming
  • Compatibility with .NET Framework

Basic Example

' A simple VB.NET "Hello, World!" program Module HelloWorld Sub Main() Console.WriteLine("Hello, World!") End Sub End Module

C++

C++ is a high-performance, general-purpose programming language that extends the C language with object-oriented features. It's ideal for systems programming, game development, and performance-critical applications.

Key Features

  • Low-level Memory Manipulation
  • Object-Oriented and Procedural Paradigms
  • Performance and Control
  • Standard Template Library (STL)

Core Concepts

// A simple C++ "Hello, World!" program #include <iostream> int main() { std::cout << "Hello, World!" << std::endl; return 0; }

JavaScript

JavaScript is the scripting language of the web. It enables dynamic content, interactive elements, and client-side logic for web applications. It's also used extensively on the server-side with Node.js.

Web Development Essentials

  • DOM Manipulation
  • Event Handling
  • Asynchronous Operations (AJAX, Promises, async/await)
  • Frameworks (React, Angular, Vue)

Client-Side Scripting

// A simple JavaScript alert alert("Hello, World!"); // Manipulating an HTML element document.getElementById("myElement").innerHTML = "Hello from JavaScript!";

Caution:

Ensure cross-browser compatibility and consider modern JavaScript features like ES6+.

TypeScript

TypeScript is a superset of JavaScript that adds static typing. It compiles down to plain JavaScript, making it ideal for building large-scale, maintainable JavaScript applications.

Benefits of Typing

  • Improved Code Readability
  • Early Error Detection
  • Enhanced Tooling and IntelliSense
  • Scalability for Large Projects

Basic Example

// A simple TypeScript function with types function greet(name: string): string { return `Hello, ${name}!`; } console.log(greet("Developer"));

F# (F Sharp)

F# is a functional-first, multi-paradigm programming language that runs on .NET. It excels in areas like data analysis, scientific computing, and complex business logic.

Functional Programming Power

  • Immutability
  • First-Class Functions
  • Pattern Matching
  • Type Inference

Concise Code

// A simple F# function let greet name = sprintf "Hello, %s!" name printfn "%s" (greet "World")
