 The `FSharp.Control.AsyncSeq` library is an implementation of functional asynchronous sequences for F#. The central type of the library is `AsyncSeq<'T>` and is a type alias for `System.Collections.Generic.IAsyncEnumerable<'T>`.

+### Comparison with `FSharp.Control.TaskSeq`
+
+A related library is [`FSharp.Control.TaskSeq`](https://github.com/fsprojects/FSharp.Control.TaskSeq/) which provides a similar API for sequences of `Task<'T>` instead of `Async<'T>`. The two libraries are very similar and the choice between them is mostly a matter of preference or performance. The `AsyncSeq` library integrates well with the F# `Async` type, while the `TaskSeq` library is more performant and integrates well with the .NET `Task` type.
+
+Both libraries implement that .NET standard `IAsyncEnumerable<'T>` interface, so they can be used interchangeably in most scenarios.
+
 ### Comparison with seq<'T>
 
 The central difference between `seq<'T>` and `AsyncSeq<'T>` can be illustrated by introducing the notion of time.
