Execution fails when using dotnet 7.x or 8.x to target net6.0 project

[plainionist]

I installed F# lint as dotnet tool as described in the documentation (version 0.24.0) and then tried to run it for a single fsproj on the command line like this:

dotnet fsharplint lint TheProject.fsproj

and i got:

Lint failed while analysing system\Bake\Bake\Bake.fsproj. Failed with: Could not load file or assembly 'System.Runtime, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

Hi @plainionist thanks for reporting this bug!

Can you try running FSharpLint with dotnet 6.x instead of with dotnet 8.x? Just to see if it's a valid workaround.

[plainionist]

i tried

dotnet fsharplint --fx-version 6.0.9 lint system\Bake\Bake\Bake.fsproj

but got exactly same error.

Lint failed while analysing system\Bake\Bake\Bake.fsproj. Failed with: Could not load file or assembly 'System.Runtime, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

[knocte]

dotnet fsharplint --fx-version 6.0.9 lint system\Bake\Bake\Bake.fsproj

Shouldn't the fx-version flag be after dotnet and before fsharplint?

[baronfel]

@knocte that's correct - the CLI parser used by the .NET Runtime (not the SDK) is very simplistic and only accepts flags between dotnet and the command to be run.

[plainionist]

even though you are right according to dotnet help, it doesn't seem to work for tools

dotnet --fx-version 6.0.9 fsharplint lint system\Bake\Bake\Bake.fsproj

Could not execute because the specified command or file was not found. Possible reasons for this include:

• You misspelled a built-in dotnet command.
• You intended to execute a .NET program, but dotnet---fx-version does not exist.
• You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.

[knocte]

Oh bummer! Then do you mind uninstalling 8.0.100 and try? This way it will run with 6.x or 7.x.

[plainionist]

After having uninstalled .NET 8 SDK, .NET 7 has been taken - unsuccessfully

dotnet fsharplint lint system\Bake\Bake\Bake.fsproj

Lint failed while analysing system\Bake\Bake\Bake.fsproj. Failed with: Could not load file or assembly 'System.Runtime, Version=7.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified. Stack trace: at Ionide.ProjInfo.ProjectLoader.loadProject(String path, BinaryLogGeneration binaryLogs, FSharpList`1 globalProperties)

Basically same error message just different verison of System.Runtime not found

[plainionist]

After having uninstalled .NET 7 SDK as well, finally, FSharpLint was executed successfully 👍

[knocte]

Oh, so with .NET6 it works? What version of .NET6 do you have?

[plainionist]

yes - works with .NET 6 - i have following versions installed

but i would prefer being able to install .NET 8 again and still use FSharpLint 😉

Of course, I never stated that this is not a bug. I was trying to see if there's a workaround so that we understand the bug better.

I might push a commit later today that might or not help with this bug; I will let you know so you can test a pre-release.

[knocte]

Ok I tried to reproduce this bug, using dotnet 7.x (in particular 7.0.115), and with the default fsproj generated by the command dotnet new classlib -lang "F#" -o src/Library, and I didn't get the crash.

@plainionist can you try to reproduce with the same dotnet new command above, and if that doesn't cause a crash, then I guess you would need to upload your special .fsproj file here.

[plainionist]

i can try later - meanwhile here is the content of the project i used for testing - maybe this helps (compile elements removed)

<Project Sdk="Microsoft.NET.Sdk">

With this I still can't reproduce it. Note I'm testing in Linux. But today a coworker managed to reproduce it (he doesn't repro in Linux, like me, but in Windows he does).

[plainionist]

i am testing on windows and even with "default f# classlib template" i get:

dotnet new classlib -lang "F#"

[Hardt-Coded]

I have the same issue, but I have an .net8.0 project.

System.Runtime, Version=8.0.0.0 missing.

[knocte]

We have managed to reproduce the problem in CI: https://github.com/webwarrior-ws/FSharpLint/commits/reproduce-687/

The tricky thing will be to fix it. Maybe switching to .net8.0 is our best bet, but:

1. I would love to find the root cause, otherwise we might need to upgrade to newer .NET versions as soon as they are released.
2. Migrating to .net8.0 might mean that people using .net6.0 cannot use the last version of FSharpLint anymore.

Help welcome :)

[Numpsy]

As a test, I tried setting the roll forward behaviour for the fsharplint tool to latestMajor (the default in the fsharp-lint nuget package is Major) and that seems to have got it to run on a .NET 6.0 project that I'm building using the .NET 8.0 SDK.

Note: When I tried it with the 0.24.0 release it didn't produce any results (which sounds like #690), but using the latest preview release worked.

[xperiandri]

I have the same issue

[Numpsy]

@xperiandri Does it work if you do

set DOTNET_ROLL_FORWARD=latestMajor

before running fsharplint (using version 0.24.2) ?

[Darkle]

I had the same issue using .Net 8 on Linux.

Using DOTNET_ROLL_FORWARD=latestMajor worked for me.

[Thorium]

Workaround: If you have .NET 8 installed and you get this error, temporarily add following globals.json to the root:

{
    "sdk": {
        "version": "6.0.403",
        "rollForward": "minor"
    }
}

Then you can run FSharpLint. And after results delete the file.
