MSDN Documentation Reference

Welcome to the Microsoft Developer Network (MSDN) Documentation, your comprehensive resource for all Microsoft technologies.

Overview

This section provides an in-depth look at the architecture, features, and best practices for developing applications on Microsoft platforms. Explore the latest innovations in Windows, .NET, Azure, and more.

Getting Started

Begin your development journey with our quick-start guides, setup instructions, and essential tools. Find the information you need to set up your development environment and write your first lines of code.

API Reference

This is the core of our documentation, offering detailed information on all available Application Programming Interfaces (APIs) across various Microsoft technologies. Navigate through namespaces to find the classes, methods, properties, and events you need.

Microsoft.Windows Namespace

Provides access to the fundamental APIs for interacting with the Windows operating system. This includes functionalities for window management, process control, registry access, and more.

Microsoft.UI Namespace

Encompasses modern UI frameworks and controls for building visually rich and responsive user experiences. This includes XAML-based UIs, WinUI, and Fluent Design System components.

System Namespace

The root namespace for fundamental types and base classes used in all .NET applications. This includes types for mathematical operations, environment information, and basic object handling.

Type	Description
`Object`	The ultimate base type for all types in the .NET Framework.
`String`	Represents a sequence of characters.
`Int32`	Represents a 32-bit signed integer.
`Boolean`	Represents a Boolean value (`true` or `false`).

System.Collections Namespace

Contains interfaces and classes that define generic collections of objects. This is essential for managing groups of objects efficiently.

System.IO Namespace

Provides types that allow reading and writing files and data streams, as well as types that handle file and directory operations. Essential for data persistence and stream manipulation.


using System.IO;

// Example: Reading a file
try
{
    string content = File.ReadAllText("myFile.txt");
    Console.WriteLine(content);
}
catch (FileNotFoundException)
{
    Console.WriteLine("The file was not found.");
}
catch (IOException ex)
{
    Console.WriteLine($"An error occurred: {ex.Message}");
}

System.Net Namespace

Provides APIs for network programming, including support for protocols like HTTP, TCP, and UDP. Enables building networked applications and services.

System.Threading Namespace

Offers types that support multithreaded programming, allowing applications to perform multiple operations concurrently. Crucial for responsive and high-performance applications.
