F# Data: Library for Data Access

The F# Data library (FSharp.Data.dll) implements everything you need to access data in your F# applications and scripts. It implements F# type providers for working with structured file formats (CSV, HTML, JSON and XML) and for accessing the WorldBank data. It also includes helpers for parsing CSV, HTML and JSON files and for sending HTTP requests.

We're open to contributions from anyone. If you want to help out but don't know where to start, you can take one of the Up-For-Grabs issues, or help to improve the documentation.

You can see the version history here.
