Download as PPTX, PDF•7 likes•2,509 views
This document discusses F# type providers, which are compiler extensions that allow F# code to access external data sources. It provides examples of built-in F# type providers that interface with data sources like XML, JSON, CSV files, databases, and web services. It also describes the FSharp.Data library which includes additional type providers for sources like HTML, WorldBank data, and more. The document encourages developing custom type providers and provides resources for doing so.
