Question

I find some good post on F#/WPF programming, but it doesn’t seem to teach a way to compile/build the code to make binary out of F#/WPF.

What command/tool do I use to build/compile this code into execution binary? Just running fsc or fsi doesn’t seem to work.

#light 
#I @"C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.0"
#r @"WindowsBase.dll"
#r @"PresentationCore.dll"
#r @"PresentationFramework.dll"

open System
open System.Windows

(* From Chap 1 - SayHello.cs *)

let win = new Window()
win.Title <- "Say Hello"
win.Show()

#if COMPILED
[<STAThread()>]
do
     let app =  new Application() in    
     app.Run() |> ignore
#endif

Answer 1

If you want to compile the code using fsc then you’ll need to remove the #I and #r commands and use a compiler command line arguments instead. The #light command is not required anymore, so you can just delete first 5 lines. In addition to the #r references, I also had to add System.Xaml.dll (which is probably new in .NET 4)

Then you can compile it using something like:

fsc.exe -r:WindowsBase.dll -r:PresentationCore.dll -r:System.Xaml.dll
        -r:PresentationFramework.dll --target:winexe Main.fs

Running the code in fsi.exe should work just fine (after adding #r "System.Xaml.dll"). Just copy the code and paste it to the F# Interactive (running either in console or in Visual Studio IDE).
