Cannot open Fsharp.Data in Visual F#

I'm learning F# by trying some example code in tryfsharp.org in Visual F#. I installed the Fsharp.Data using nuget package console:

Install-Package FSharp.Data 

'FSharp.Data 2.1.1' already installed.
Adding 'FSharp.Data 2.1.1' to TryFsharp.
Successfully added 'FSharp.Data 2.1.1' to TryFsharp.

When I try to reference it:

#r "Fsharp.Data.dll"
Program.fs(10,1): error FS0084: Assembly reference 'Fsharp.Data.dll' was not found or is invalid

open Fsharp.Data
Program.fs(11,6): error FS0039: The namespace or module 'Fsharp' is not defined

Here is my project structure:

|-- ArchitectureExplorer
|-- Backup Files
|   |-- ConsoleApplication1
|   |-- ConsoleApplication2
|   |-- ConsoleApplication3
|   |-- ConsoleApplication4
|   |-- FSharpKoans

    |-- FSharp.Data.2.0.14
    |-- FSharp.Data.2.1.1
    |-- FsCheck.1.0.4
    `-- repositories.config

Is there any extra step I need to do before using it?

Maybe not optimal solution but for testing purposes in interactive F# I use real paths like

#r "packages/FSharp.Data.2.2.5/lib/net40/FSharp.Data.dll"
#r "bin/Debug/FSharp.Data.SQLProvider.dll"

As you can infer from you error message, you need to specify correct location of Fsharp.Data.dll with your #r directive. It could be relative to your current directory or absolute.

Alternatively(more easy IMO), you can install F# Power Tools and use it's Send To Interactive feature - just right-click on assembly in References and select this option.
