Very interesting !!
I made some modifications to your code to allow it compile F# into memory.

Hope it helps:
#path to FSharp Compiler Provider assembly DLL $fsharp_codedom = "$env:ProgramFiles (x86)\FSharp-1.9.7.8\bin\FSharp.Compiler.CodeDom.dll";


#load compiler  assembly

$codedom_assy=[System.Reflection.Assembly]::LoadFrom($fsharp_codedom);
#instantiate compiler and parameters

$compiler = new-object -type Microsoft.FSharp.Compiler.CodeDom.FSharpCodeProvider;

$compilerParameters = new-object -type System.CodeDom.Compiler.CompilerParameters;
#force assembly to be compiled in memory

$compilerParameters.GenerateInMemory=$true;
# FSharp Source

$source=@"

#light

module Strangelights.Fibonacci

let fibs =

    (1,1) |> Seq.unfold

        (fun (n0,n1) ->

            Some(n0, (n1, n0 + n1)))
let get n =

    Seq.nth n fibs
"@
$result = $compiler.CompileAssemblyFromSource($compilerparameters,$source);

if ($result.Errors.HasErrors){ $source;$result.Errors;break}

#calling FSharp functions from powershell 1..40| ForEach { "{0} {1}" -f $_, [Strangelights.Fibonacci]::get($_) }
