Source code generator how to get an Assembly object?

Question

C++ / C#

I'm just interested in working with reflection, I did not find information on how to do this (apparently I was looking badly) and the only thing that comes to mind is working with the syntax tree.

Answer 1

Inside the Source Generator, you cannot access reflection, since reflection works with already compiled code.
So the analysis of the AST and the semantic model is the only way out.
