Burst and IL2CPP are different things. Burst is also a different “can’t believe it’s not c#” custom layer they invented, own and now have to maintain a separate fork of.
(Apparently just maintaining IL2CPP wasn’t keeping them busy enough)
If you're talking about Burst then it would be more correct to say they added another language that is similar to but different than C#. AOT Burst builds a native library so I don't believe there's a C++ step.
