On WSL/Fedora 43, building hello world:

    > time dotnet publish
    Restore complete (0.4s)
      dn-hw net10.0 linux-x64 succeeded (2.4s) → bin/Release/net10.0/linux-x64/publish/

    Build succeeded in 3.1s

    real    0m3.571s
    user    0m2.784s
    sys     0m0.673s

    > time go build main.go

    real    0m3.309s
    user    0m8.864s
    sys     0m1.741s

Obviously I don't know how that translates to a non-trivial application.
