FsToolkit.ErrorHandling V: The Final Frontier

Watch this session

Introduction

FsToolkit.ErrorHandling has become a staple in the F# community for handling the Result type and making Railway-Oriented-Programming a breeze. It has been used in many projects and has been a great library for many developers. At the time of writing it has 3.4 million downloads on Nuget for the main package and 2.2 million for the TaskResult package. A big thank you for all the users and contributors to the project!

Topic

Version 5.0 is on the horizon! This will have many breaking changes and their reasons why. We’ll cover all that is going into the release such as:

• Removing Ply from the project
• Moving TaskResult into the Core Library and deprecating FsToolkit.ErrorHandling.TasksResult package.
• Allowing netstandard2.0 to deal with IAsyncEnumerable/IAsyncDisposable
• Fixing overload resolution
• What does god need with a starship?
• Removing/changing and! for AsyncResult and TaskResult

We’ll also look into merging outstanding PRs and working on remaining issues.
