When packing an F# project that depends on another project via ProjectReference a spurious Build is triggered on the base project. This triggers the SDK error NETSDK1085. It doesn't seem to matter if the project being referenced is an .fsproj or .csproj. In both cases the preojct being referenced will be re-built and trigger the error. Executables being packed as tools don't seem to trigger this behaviour.

dotnet new classlib --language F# --name eff -o eff
dotnet new classlib --language F# --name gee -o gee
dotnet add gee/gee.fsproj reference eff/eff.fsproj
dotnet build gee/gee.fsproj && dotnet pack gee/gee.fsproj --no-build

• Gist
• Gist ZIP Download

Expected behavior

The project should produce a NuGet package with no errors

Actual behavior

The error NETSDK1085 is reported:

/usr/lib64/dotnet/sdk/5.0.206/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.targets(146,5): error NETSDK1085: The 'NoBuild' property was set to true but the 'Build' target was invoked. [/testing/Gee.fsproj]

Known workarounds

Don't provide the --no-build flag when packing.
