Doesn't run on Solaris and doesn't run on FreeBSD. An 'LTS' release means ... about 3 years. No thanks...
LTS releases are every 2 years and there is a major version release every year. .NET 6 LTS .NET 7 .NET 8 LTS FreeBSD support has been in the works for a while: - https://wiki.freebsd.org/.NET - https://github.com/dotnet/runtime/issues/14537
From my perspective, this is not "long term" ; but maybe others view it differently.
