Issue with mono version

[halcwb]

I have an issue with the mono version used. I get a file not found error in the fsi when I want to use a function that uses another function from a different dll:

$>heroku run bash
- #load "src/Informedica.GenUnit.App/Scripts/load-references-release.fsx";;
[Loading /app/src/Informedica.GenUnit.App/Scripts/load-references-release.fsx]

namespace FSI_0002

> open Informedica.GenUnits.Lib;;
> Api.eval;;
val it : (System.String -> string) = <fun:it@4>
> "200 mg[Mass]" |> Api.eval;;

However I can open the Informedica.GenUtils.Lib and use any function from that lib directly. This issue doesn't occur in my local mono install. Only in the heroku mono install version.

So, would it be possible that you upgrade your mono builder to a later stable version?

Do you reference Informedica.GenUtils.Lib.dll in the fsx script ?

#r "pathtodll/Informedica.GenUtils.Lib.dll"

Yes, I do. I have the same setup working on Azure. It also works when I run this on my local windows machine and when I run it under os x, running a different mono version. So, I think it's the mono version. If I wouldn't have referenced Informedica.GenUtils.Lib, I couldn't have run a function from that lib.

You can find my setup in my GenUnitApp repo.

In your demo, it works because you only use a direct reference to suave, and suave itself doesn't have any indirect dependencies outside the GAC. It happens when you call a function from a lib, that itself depends on another lib outside the GAC, i.e. in the packages dir. I also checked in the heroku bash that the lib was indeed in the packages dir. Indeed I can reference it in the fsharpi as I mentionned.
