Replacing Razor and/or T4 for code generation?

Question

C++ / C#

Who can advise what to replace Razora in code generation?
Razor is known to have a lot of auto-formatting issues in VStudio that get around editing the template in VSCode. but still.
requirements:
- the syntax of the template engine is C#, without the need to stick in your syntax.
- syntax highlighting, albeit in VSCode.
I saw a link to such a template engine in topics devoted to code generators, but I can't find it.
