Microsoft Namespace

This documentation covers the core APIs within the Microsoft namespace and its sub-namespaces, providing fundamental building blocks for .NET applications.

Example Usage: Basic Class


// Example of using a class from the Microsoft.Net.Sdk.Web namespace
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

var builder = WebApplication.CreateBuilder(new string[] {});

// Add services to the container.
builder.Services.AddControllersWithViews();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseDeveloperExceptionPage();
}

app.UseRouting();

app.UseAuthorization();

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?});

app.Run();

System Namespace

The System namespace is the foundational namespace for .NET applications, containing fundamental types and base classes.

Interfaces

System.IDisposable
System.ICloneable
System.IComparable

Structs

System.Boolean
System.DateTime
System.TimeSpan

Enums

System.TypeCode
System.DayOfWeek

System.Collections Namespace

Provides interfaces and classes that define how reference and value collections can be used, manipulated, and queried. This namespace includes non-generic collections.

Classes

System.Collections.ArrayList
System.Collections.Hashtable
System.Collections.Stack
System.Collections.Queue

Interfaces

System.Collections.ICollection
System.Collections.IEnumerable
System.Collections.IDictionary
System.Collections.IList

System.Collections.Generic Namespace

Provides interfaces and classes that define generic collections, which allow developers to create collections that help prevent runtime type errors and improve performance by enabling collection element type checking at compile time.

Classes

System.Collections.Generic.List<T>
System.Collections.Generic.Dictionary<TKey, TValue>
System.Collections.Generic.HashSet<T>
System.Collections.Generic.LinkedList<T>
System.Collections.Generic.Queue<T>
System.Collections.Generic.Stack<T>

Interfaces

System.Collections.Generic.ICollection<T>
System.Collections.Generic.IEnumerable<out T>
System.Collections.Generic.IDictionary<TKey, TValue>
System.Collections.Generic.IList<T>
System.Collections.Generic.IReadOnlyCollection<out T>

System.IO Namespace

Provides types that allow reading and writing to and from different kinds of storage media. This namespace includes types for file streams, memory streams, and stream readers/writers.

Classes

System.IO.File
System.IO.Directory
System.IO.StreamReader
System.IO.StreamWriter
System.IO.FileStream
System.IO.MemoryStream

Enums

System.IO.FileMode
System.IO.FileAccess
System.IO.SeekOrigin

System.Linq Namespace

Provides classes and interfaces that support LINQ (Language Integrated Query) functionality. LINQ allows you to write queries against any data source that implements the IEnumerable<T> or IQueryable<T> interfaces.
