C# Async Patterns

Master asynchronous programming in C# using async/await, Task, ValueTask, async streams, and cancellation patterns. This skill covers modern asynchronous patterns from C# 8-12 for building responsive, scalable applications.

Async/Await Fundamentals

The async/await pattern provides a simple way to write asynchronous code that looks and behaves like synchronous code.

Basic Async Method

public async Task<string> FetchDataAsync(string url)
{
    using var client = new HttpClient();
    string result = await client.GetStringAsync(url);
    return result;
