.NET Framework Multithreading

Welcome to Multithreading Documentation

The .NET Framework provides a rich set of classes and patterns to create robust multithreaded applications. This guide covers fundamental concepts, the Thread class, the Task Parallel Library (TPL), async programming, and synchronization mechanisms.

Key Concepts

• Thread: Represents an OS thread.
• Task: Represents an asynchronous operation, managed by the TPL.
• Async/Await: Language constructs that simplify asynchronous code.
• Synchronization: Tools such as lock, Mutex, SemaphoreSlim, and ConcurrentCollection.

Getting Started

Explore the topics on the left to dive deeper. Below is a quick example of creating and starting a thread:

using System;
using System.Threading;

class Program{
    static void Main(){
        Thread t = new Thread(Worker);
        t.Start();
        Console.WriteLine("Main thread continues...");
    }
    static void Worker(){
        Console.WriteLine("Worker thread is running.");
    }
}

For modern code, consider using Task.Run:

using System;
using System.Threading.Tasks;

class Program{
    static async Task Main(){
        await Task.Run(()=> DoWork());
        Console.WriteLine("Work completed.");
    }
    static void DoWork(){
        // Simulate work
        Thread.Sleep(1000);
    }
}
