Async Programming

Asynchronous programming enables your application to perform long-running operations without blocking the main thread. This improves responsiveness and scalability by allowing multiple operations to run concurrently.

Async/Await Pattern

The async/await pattern provides a clean and intuitive way to write asynchronous code. It simplifies handling operations that might take a long time to complete, such as network requests or file operations.

public async Task<string> GetDataAsync()
{
    using var client = new HttpClient();
    return await client.GetStringAsync("https://api.example.com/data");
}

// Usage
string result = await GetDataAsync();

Task Parallel Library

The Task Parallel Library (TPL) provides powerful tools for parallel and asynchronous programming. It helps you maximize CPU usage and improve performance through parallel execution.

// Parallel ForEach
Parallel.ForEach(items, item =>
{
    ProcessItem(item);
});

// Task.WhenAll
Task[] tasks = urls.Select(url => DownloadAsync(url)).ToArray();
await Task.WhenAll(tasks);
