C# uses Task and async/await to run code asynchronously (in the background).

💼 Awaiting Async Methods
You can await any method that returns a Task or Task<T>.

async Task<int> GetNumberAsync()

await Task.Delay(500);
return 42;
}
async Task UseNumberAsync()
{
int n = await GetNumberAsync();
Console.WriteLine(n);
}
📝 Why Await?
- Keeps your app responsive.
- Lets you write code that looks synchronous, but isn’t.
💡 Try It!
Write a method that fetches data asynchronously (simulate with Task.Delay), then prints the result.
