JsonProvider unusable

Trying to use the json type provider, unsuccesfully. After runnings the following commands :

I can't seem to be able to make the following error go away : JsonProvider is undefined

open FSharp.Data
open Microsoft.FSharp.Data.TypeProviders

type JsonObj =  JsonProvider<"http://shopicruit.myshopify.com/products.json">

I'd like to know what's currently missing because I can't see why this F# snippet is not right.

UPDATE

Here's a capture of my installs

Here's a capture of my type provider settings. (They were already enabled). I don't get what I'm missing at the moment...

When installing a NuGet Package to a project via the Package Manager Console, make sure that the value in the "Default project" field is the project you want to install the package to: Package Manager Console

This has happened to me many times, including while trying to reproduce your issue. Also, as @Tomas Petricek says in the comments - both to your question and to my previous attempt at an answer here - you don't need to open Microsoft.FSharp.Data.TypeProviders. JsonProvider works with just a reference to FSharp.Data.

In case you mistakenly installed the package to the wrong project, you can either:

  • Use Uninstall-Package to remove it, again making sure the "Default project" field targets the project in question, or;
  • Right-click on "References" under said project, then pick "Manage NuGet Packages". This will open the NuGet Package Manager window, from which you can also uninstall whatever you don't need.
