Seems to be an issue with the build.fsx, but i have no idea how to adress this.

Pretty sure i encountered it already in other projects which i then upgraded to use a build.fsproj to circumvent this.

can you try updating the fake-cli dotnet tool from the current 5.21 alpha to 5.22.0 and see if that resolves the issue?

[baronfel]

Otherwise, FAKE isn't doing anything incredibly complex, so a simple dotnet build should work for you.

[Freymaurer]

Hey thanks for the fast reply! But I tried that already:

1. I changed the version in dotnet-tools.json
2. delete .fake folder
3. dotnet tool restore
4. retry dotnet fake build

Same error as before.

Ah, yeah i get what you mean. Skip FAKE and use the commands directly, yeah that actually works. Pretty dumb to not think of that myself 😞

Identical problem on Linux: #103 (comment)

For reference, it does not. The targeting pack must be at the exact path, and be the exact version that fake-cli is looking for:

 'C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref\6.0.0\ref\net6.0', please check installed SDK and runtime versions
