Before you begin

This is an F# language class. To complete the coding exercises, you will need a Xamarin development environment with either a simulator/emulator or a device to run the exercise on. Please read the setup requirements if you need help installing the Xamarin development environment.

Overview

During this course we cover the basics of using type providers in F#. Including defining what a type provider is, illustrating how to connect to them, and ultimately how to transform data from a type provider.
