Xamarin studio F#

[mtj_tj]

Hey everyone

I’m trying to create a program for the MonoBrick Firmware using F#.
I want to be able to debug the program, should any exceptions occur and I’m therefore using Xamarin Studio with the Add-In.
C# compilation and connection over WiFi works fine, but I cannot compile my F# programs when using Mono, it works fine when using .NET but then I can’t use the MonoBrick Add-In and thus have no debugging.
I have created a new Solution using the MonoBrick Project and then added a new F# project to the solution.

Does anyone have any experience with F# in Xamarin? I already have the F# Language Binding Add-in.
I do not have another choice concerning programming language.

My code is as simple as this:

open MonoBrickFirmware.Display

[<EntryPoint>]
let main argv = 

    LcdConsole.WriteLine("Test")

    printfn "%A" argv
    0 // return an integer exit code

And this is my stacktrace when using Mono:

Building: ftester (Debug|x86)

Hi there

I just merged this pull request to the master branch. I will create a new version of the add-in and upload it to my FTP server this weekend. In the meantime I think that what you are experiencing is related to the missing DLL. You have to add the DLL using gacutil. This will be included in the next image release.

Hey Anders

Thanks a lot, I’ll wait patiently for the new Add-In 🙂
I tried adding the DLL using gacutil after giving it a strong name, afterwards I added it to the project by browsing “C:\Windows\Microsoft.NET\assembly\GAC_MSIL\MonoBrickFirmware”, but I had no luck getting it to work.

Kind regards.

Hi there

Try to have a look at this. That guy must know how to do it…
