Why can't I open FSharp.Data module in Visual Studio

Question

I have a module UserSpec defined as

module UsersSpec
open FSharp.Data
type schema = FSharp.Data.JsonProvider<"UserSpec.json">

and I have the FSharp.Data.TypeProviders nuget package installed

Packages

But I get the compile error

Error 1 The namespace or module 'FSharp' is not defined C:\Users\egger\Workspace\Weingartner.Distribution\Weingartner.Distribution.Accounts.Spec\UsersSpec.fs 3 6 Weingartner.Distribution.Accounts.Spec

Why can't I open the module?

Answer 1

Don't install nuget package FSharp.Data.TypeProviders. Just Install FSharp.Data.
