News to me! I always deploy .NET 5/6 stuff on Linux, explains why I'm out of the loop. Thanks!
You missed how there effectively isn't a .NET Core/.NET Framework delination anymore. It is just .NET, and .NET gets security patches from Windows Update.
.NET Core got renamed into .NET as of .NET 5, and it is still quite relevant to make a difference, plenty of people still don't get it.
