Can't run first sample in Expert FSharp book
f#book

The first sample includes:

let wordCount text =
let words = String.split [' '] text
let wordSet = Set.of_list words
let nWords = words.Length
let nDups = words.Length - wordSet.Count
(nWords , nDups)

This compiles, but gives this runtime error when called:
The value, constructor, namespace or type 'split' is not defined. A construct with this name was found in FSharp.PowerPack.dll, which contains some modules and types that were implicitly referenced in some previous versions of F#. You may need to add an explicit reference to this DLL in order to compile this code.

I do have a reference to that .dll. It seems I should reference it with open FSharp.PowerPack, but that doesn't work.

.

Sorry, I'm executing this by selecting it in VS2008 and hitting alt+enter. The project is targeting .Net 3.5.

For the interactive window, you need to use

#r "FSharp.PowerPack.dll";;

to reference the powerpack (or any library).

#r "FSharp.PowerPack.dll";;

Crap, I typed that in, got the red squiggly (b/c it was a .fs file), and didn't even execute it.

Typing #r @"FSharp.Powerpack";; in the FSI fixes that problem in v1.9.6.16. i am working in XP 64 bit.

results:

> #r @"FSharp.Powerpack";;

--> Referenced 'C:\Program Files (x86)\FSharp-1.9.6.16\bin\FSharp.Powerpack.dll'
