5. Asynchronous Programming with Task and async/await

Overview: Write non-blocking asynchronous code in C# using Task, Task<TResult>, and the async/await pattern.

Concept & Syntax Guide

Asynchronous programming prevents thread pool starvation and keeps user interfaces responsive. The `async` keyword enables `await` expressions within a method, which pauses execution until the awaited Task completes.

Hands-On Practice Exercise
