9.0.100-preview.7

Build from runtime, aspnetcore and sdk repos directly under FreeBSD x64 and arm64.
For build procedure check scripts in repo.

Ilc should work, but manual change is needed, after project restore, edit ~/.nuget/packages/microsoft.dotnet.ilcompiler/9.0.0-preview.7.24405.7/build/Microsoft.NETCore.Native.targets and add <IlcArg Condition="'$(_targetOS)' == 'freebsd' and '$(IsNativeExecutable)' == 'true'" Include="--export-dynamic-symbol:__progname;--export-dynamic-symbol:environ" /> somewhere around line 247
