You keep repeating this, sorry but it only goes to show how 
little you know about the modern Microsoft ecosystem.

Not only did Managed C++ evolve into C++/CLI, did C++/CLI get 
updated to C++20 back in 2023, and has several bug fixes coming 
up on Visual Studio 2022 17.4.

C++/CLI is the to go tool for many developers that rather not 
spend all day writing P/Invoke attributes, when it is a big C++ 
library being added into a .NET project.
