F# Wrong Order of Assemblies / nuget packages loaded....

Describe the bug

I load all dependencies /nugetpackages at the top of the notebook file. but i got errors that the typ is unkown…

when i try this in dotnet core under cli this working correctly…

i have also the little jupyter file attached… it is easier to see the problem i think

aarvark.zip

Did this error occur while using dotnet try or online?

• dotnet-try
• [x ] .NET Jupyter Notebook
• [ x] online

What kind of error was it?

• User Interface (UI): For example the output never displayed
• Service Error: For example “The service is temporarily unavailable. We are working on it”
• [x ] Other: input.fsx (18,8)-(22,10) typecheck error The type referenced through ‘FShade.Imperative.Module’ is defined in an assembly that is not referenced. You must add a reference to assembly ‘FShade.Imperative’.

Screenshots

Please complete the following:

• OS
  • Windows 10

i revisited this issue, error reporting is much better now, all works now 😃 @dhabe1982

@dhabe1982,

Thanks for this, it is a really cool issue …

I took a look at this and I believe the order of #r shouldn’t really have impacted the compilation, so clearly we have some sort of bug.

My suspicion is that the type provider is initialized with references as soon as it’s dll referenced with “#r” rather than when we try to compile some code.

Given that references are discovered using “nuget” there is not really a good mechanism for modifying the #r order for discovered transient dll references, so we should probably try to nail down whether it is due to type provider initialization and figure out how to smooth out that experience.

In the meantime this works for me

Add a new cell at the front with it works by ensuring that FShade.Imperative is referenced and loaded before the type provider assembly is are loaded:

#r "nuget:FShade.Imperative, 4.3.9"
open FShade

#r "nuget:Aardvark.Base, 4.5.15"
#r "nuget:Aardvark.Base.FSharp, 4.5.15"
#r "nuget:Aardvark.Base.Incremental, 4.5.15"
#r "nuget:FShade.Core, 4.3.9"
#r "nuget:FShade, 4.3.9"
#r "nuget:FShade.GLSL, 4.3.9"
#r "nuget:Aardvark.Base.Rendering, 4.5.11"

 
open Aardvark.Base
open FShade
   
let a : FShade.Effect = Unchecked.defaultof<_>
let b = 1
type Data = { pos : V4d; tc : V2d }
   ….
