Fsharp: dependency issues with dotnet fsi

[OnurGumus]

I am using .net core preview 5 with dotnet fsi I have the following code using FSharp.Literate

#I "./packages"
#r @"FSharp.Literate/lib/netstandard2.0/FSharp.Markdown.dll"
#r @"FSharp.Literate/lib/netstandard2.0/FSharp.CodeFormat.dll"
#r @"FSharp.Literate/lib/netstandard2.0/FSharp.Literate.dll"
#r @"NetStandard.Library/build/netstandard2.0/ref/netstandard.dll"
open FSharp.Literate
Literate.ParseScriptString(null)

//Literate.ProcessScriptFile(null)

The first line causes :
error FS0193: Could not load file or assembly 'FSharp.Compiler.Service, Version=27.0.1.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

If you comment that line and uncomment second one you get:
error FS3216: type 'FSharp.CodeFormat.CodeFormatAgent' not found in assembly 'FSharp.CodeFormat, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. A possible cause may be a version incompatibility. You may need to explicitly reference the correct version of this assembly to allow all referenced components to use the correct version.

It feels like this is by design, you need to reference all dependencies as well? Or do I miss something obvious?

[cartermp]

You shouldn't need to do that, no. Especially not netstandard.dll. But given that it's still in preview there could be something wrong going on.

[KevinRansom]

@OnurGumus I presume you used nuget or paket to pre-fetch all of the required dependencies. Could you please specify the complete steps to repro this:

For sure you will need to specify a:

r to the fsharp.compiler.service.

The netstandard.dll reference seems very wrong. although I doubt if it would do any harm, since it is already referenced.

Thanks

@KevinRansom I know, using netstandard.dll is very wrong, I added these while trying to diagnose. But they don't change the result. Here are the full steps for reproduction:
In an empty directory,

dotnet tool install --tool-path .paket Paket

.paket\paket init

.paket\paket add FSharp.Literate

Then create a test.fsx file by using an editor put the above content. You can remove things like netstandard as it doesn't fix anything. After that run:

dotnet fsi test.fsx

The output is :
error FS0193: Could not load file or assembly 'FSharp.Compiler.Service, Version=27.0.1.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

Yes I believe that should work, and it doesn't. There is a minor issue with your repro. the #I should be

I "../packages"

However, even correcting that it fails:

````

I will take a look when I get a chance.

@KevinRansom I think you've got the wrong tag 😄

[KevinRansom]

@OmarTawfik, hey mate, I did indeed.

[KevinRansom]

@OnurGumus do you still have an issue?

[OnurGumus]

@KevinRansom Above steps still produce the same problem.

[dandereggK]

Commenting to track the issue, because I have a nearly identical error FS3216 with #r "Microsoft.ServiceFabric.Client.Http\lib\netstandard2.0\Microsoft.ServiceFabric.Client.dll"

[OnurGumus]

With preview 9 the issue still persists as of today.

Tagging as a backlog item for .NET Core 3.1 - @KevinRansom this and the FSI-using-mono.posix issue should be slated for .NET Core 3.1

@OnurGumus You can work around the issue with this hack for now:

// HACK: force usage of Fsharp.Compiler.Services
// or the indirect reference from FSharp.Literate will fail to load
let dummy (pos: FSharp.Compiler.Range.pos) =
    pos.Column
FSharp.Compiler.Range.mkPos 1 1 |> dummy

Found this in a Github Issue for Literate.

[OnurGumus]

I didn't try the original case but my original goal was to use
FSharp.Compiler.Service
and Fsharp.Literate.
Now they work out of box with .net core .net 3.1.
I don't have any complaints any more. Should I close the issue ?

@OnurGumus Please feel free to close unless @KevinRansom has any objections
