my small project has two files, umg.cpp (unmanaged c++) and mged.cpp
(MC++), and unmanged code will call managed code. However, I cannot
debug from unmanged code into managed code. Can anyone help me to solve
the problem?

I have a class that is writen in unmanaged pure native C++.
This class files (h and cpp) are inserted to a managed C++ (VC++ 2005,
C++/CLI) DLL compoenet.
This DLL compoenet is used in a C# application.
My question is:
Does the performance of the unmanaged pure native C++ class described above
is the same if it was a in a pure unmanaged native C++ DLL component?

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
