F# XNA FSC Binding Problem
f#silverlightxnafsc

I'm trying to get F# to work with Silverlight 5.0's XNA, to do 3D graphics. There are not a lot of good examples that are available on the web. I decided to write a F# DLL and incorporate that into a C# program. Anyway, I can't get said DLL to incorporate XNA. I use FSC to compile the DLL with the command line:

Fsc.exe -o:xbox.dll --noframework -r:"C:\Users\Luke\Downloads\fsharp\FSharp-2.0.0.0\Silverlight\5.0\bin\FSharp.Core.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\Microsoft.Xna.Framework.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\Microsoft.Xna.Framework.Graphics.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\Microsoft.Xna.Framework.Graphics.Shaders.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\mscorlib.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\System.Core.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\System.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\System.Windows.dll" -r:"c:\Program Files\ReferenceAssemblies\Microsoft\Framework\Silverlight\v5.0\System.Windows.Xna.dll" --target
:library --warn:3 --warnaserror:76 --fullpaths --flaterrors Physicals.fs

The code I am trying to compile (Physicals.fs) is:

1

#light
//namespace DefaultNamespace
module Sample.DirectX
//module Physicals =
open System
open System.Windows
open System.Windows.Graphics
open Microsoft.Xna.Framework
open Microsoft.Xna.Framework.Graphics
open Microsoft.Xna.Framework.Graphics.Shaders
open System.Collections.Generic
open Microsoft.FSharp.Core
open Microsoft.FSharp.Core.OptimizedClosures


module MathOps = 
    type time = float
    let sucks () = Microsoft.Xna.Framework.Vector3(1.0f, 1.0f, 1.0f)
    let sqr (x:float32) = x * x
    let pi = Math.PI |> single

The error I get is:
Physicals.fs(19,44): error FS0039: The value, constructor, namespace or type 'Vector3' is not defined

Basically I am not binding to the XNA dlls at all. I have tried some basic changes to this, I guess you never know when you've done something completely stupid but the mistake is not obvious (to me), like a misspelling. So what am I doing wrong? Thanks for looking!

.

Solved. I needed to add a few more DLLs, Microsoft.Xna.Framework.Math.dll in particular, in the linking, but I didn't need to open them. The correct way to compile the DLL is:

Fsc.exe -o:xbox.dll --standalone --noframework --define:TRACE --optimize+ --tailcalls+ -r:"C:\Users\Luke\Downloads\fsharp\FSharp-2.0.0.0\Silverlight\5.0\bin\FSharp.Core.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\Microsoft.Xna.Framework.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\Microsoft.Xna.Framework.Graphics.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\Microsoft.Xna.Framework.Graphics.Shaders.dll" -r:"c:\Program Files\Microsoft SDKs\Silverlight\v5.0\Libraries\Client\Microsoft.Xna.Framework.Math.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\mscorlib.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\System.Core.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\System.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\System.Windows.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\System.Net.dll" -r:"c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v5.0\System.Windows.Xna.dll" --target:library --warn:3 --warnaserror:76 --fullpaths --flaterrors Physicals.fs

I've got a new project started that uses Intellisense, for some reason only a small amount of the Microsoft.Xna.Framework is available with F#, under C# it is all available. I seem to be using the correct Silverlight 5 XNA DLL for both, what could be the problem?

for example I initially tried:

1

let sucks () = Vector3(1.0f, 1.0f, 1.0f)

I have successfully used XNA with F# for a desktop and a WP7 phone game (but not Silverlight).

I would recommend starting with one of the F# XNA project templates available for visual studio. Just search the gallery.
