FCS makes paket to make wrong load script file ( do not work well on Mono )

following that

#r "ISymWrapper, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" 
#r "System.IO, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" 
#r "System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

Repro steps

step1: install library

$ paket init
$ vim paket.dependencies 

source https://www.nuget.org/api/v2
generate_load_scripts: true
nuget fsharp.compiler.service

$ paket install

step2: run fsx file

$ vim foo.fsx

#load @"./.paket/load/net471/main.group.fsx"
"hello" |> stdout.WriteLine

$ fsharpi foo.fsx

/Users/callmekohei/tmp/foo/.paket/load/net471/main.group.fsx(46,1)

Oh... I mistake to put it out (^_^;;

I'll close this issue.

see alse:
fsprojects/Paket#3194

[callmekohei]

So I think FSC make it to improve dependencies.

I'll re-open this issue.

sorry (^_^;;

Is there a reason ISymWrapper is not part of mono install? it might be an issue with mono itself.

@smoothdeveloper

Oh! Hmm...

I think FSC make it to improve dependencies, but your opinion is reasonable.

So I put issue to mono.

mono/mono#8640

[callmekohei]

Hello!

So I hear from @akoeplinger , I think it better that FCS creates modified FCS.nuspec file.

(before)

<?xml version="1.0" encoding="utf-8"?>
<package xmlns="http://schemas.microsoft.com/packaging/2013/05/nuspec.xsd">
  <metadata>
    <dependencies>
      <group targetFramework=".NETFramework4.5">
        foo
      </group>
      <group targetFramework=".NETStandard2.0">
        bar
      </group>
    </dependencies>

    <frameworkAssemblies>
      <frameworkAssembly assemblyName="ISymWrapper, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" targetFramework=".NETFramework4.5" />
      <frameworkAssembly assemblyName="System.IO, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" targetFramework=".NETFramework4.5" />
      <frameworkAssembly assemblyName="System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" targetFramework=".NETFramework4.5" />
    </frameworkAssemblies>

  </metadata>
</package>

(after)

<?xml version="1.0" encoding="utf-8"?>
<package xmlns="http://schemas.microsoft.com/packaging/2013/05/nuspec.xsd">
  <metadata>
    <dependencies>

      <group targetFramework=".NETFramework4.5">

        foo

        <dependency id="ISymWrapper    "  Version="4.0.0.0" exclude="Build,Analyzers" />
        <dependency id="System.IO      "  Version="4.0.0.0" exclude="Build,Analyzers" />
        <dependency id="System.Runtime "  Version="4.0.0.0" exclude="Build,Analyzers" />

      </group>

      <group targetFramework=".NETStandard2.0">
        bar
      </group>

    </dependencies>

  </metadata>
</package>

But I don't know how to change fsharp.compiler.service's code.

I'm glad anyone to advice me.

Thanks 😄
