Iterating with Async Enumerables | | Exploring C# and DOTNET | Rahul Nath

Enumeration of collections has been the bread-and-butter of many programs.

But what if we could enhance this familiar concept with asynchronous capabilities? That's what .NET AsyncEnumerables does.

In this video, we'll explore how C# combines 'yield return' with 'async' and 'await' to create efficient asynchronous data streams and how 'await foreach' lets us effortlessly consume them.

For the demo, I will show you a simple console application that looks through rating files stored in an Amazon S3 bucket to find the first n number of x-star ratings for a given product. We will see some of the challenges with standard approaches and how to use AsyncEnumerable to help us make this more efficient.
