namespace or module FsCheck is not defined

I am starting to get my hands dirty with F# on Mac OS X but can't make it to work (F# version is 3.1 and Mono version is 4.0.2). I am using packet for dependency management and have already installed some libraries. This is how my packet.dependencies file looks like:

source https://nuget.org/api/v2

nuget Neo4jClient >= 1.0.0.664
nuget FsCheck

After mono .paket/paket.exe install I get related dependencies successfully downloaded into a packages folder. The auto-generated packet.lock file looks like the following:

NUGET
  remote: https://nuget.org/api/v2
  specs:
    FsCheck (2.0.5)
      FSharp.Core (>= 3.1.2.5)
    FSharp.Core (4.0.0.1)
    Microsoft.Bcl (1.1.10)
      Microsoft.Bcl.Build (>= 1.0.14)
    Microsoft.Bcl.Build (1.0.21)
    Microsoft.Net.Http (2.2.29)
      Microsoft.Bcl (>= 1.1.10)
      Microsoft.Bcl.Build (>= 1.0.14)
    Neo4jClient (1.0.0.664)
      Microsoft.Net.Http
      Newtonsoft.Json (>= 6.0.3)
    Newtonsoft.Json (7.0.1)

I am trying to reference such libraries within my .fs files:

#if INTERACTIVE
#r "./packages/FsCheck/lib/net45/FsCheck.dll"
#endif

open FsCheck

open FsCheck statement fails with The namespace or module 'FsCheck' is not defined.

What am I doing wrong?

EDIT:

Switching to .fsx (instead of .fs) and removing the #if part works fine. With .fs it compiles but when running the .exe I get the following exception (I understand it means the .dll isn't bundled by default, in which case I wonder what the common practice is):

Unhandled Exception:
System.IO.FileNotFoundException: Could not load file or assembly 'FsCheck, Version=2.0.5.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

  1. Do you have a paket.references file in your project?
  2. Did you add "FsCheck" to it?
  3. Have you set the target framework of your project to .NET 4.5?

If you are using Xamarin Studio, your project target framework is probably set to .NET 4.0. You can change this in Project Options > Build > General.

You can also specify the target framework in paket.dependencies. You need step 3 though.

framework: net45
source https://nuget.org/api/v2

nuget Neo4jClient >= 1.0.0.664
nuget FsCheck

Your path is missing the version. It should be

#r "./packages/FsCheck.2.0.5/lib/net45/FsCheck.dll"
