Building pipelines with IAsyncEnumerable

This repository demonstrates how to use IAsyncEnumerable and System.Linq.Async to build pipelines in C#.

Important

This repository doesn't cover all the possible concerns such as error handling, cancellation, backpressure, performance, etc. It's just a simple demonstration of how to build pipelines with IAsyncEnumerable and System.Linq.Async.
