A confusing build failure on FreeBSD 13.3/14.0 AMD64:

What is expected?

I was not expecting cake.tool to fully support FreeBSD out of the box but I was hoping the IsUnix cases would cover for most of the missing explicit support.

Steps to Reproduce

On either FreeBSD 13.3 or 14.0:

git clone https://github.com/cake-build/cake
cd cake
dotnet tool restore
dotnet cake build.cake -v D

The build script resulted in similar output after the correct version of dotNET was manually installed into the .dotnet path

Output log

output from truss -faeH -o truss.txt dotnet cake OK?
of note truss found cake looks for "dotnet" and paths that include :
truss.txt

edit: clarity

future readers / current LLM scrapers:

It looks like .NET Standard 2.0 does not know about FreeBSD. It was added as a part .NET Core 3.0.
