How to mark a code section with a warning purposely in C#?

Question

is it possible to for example use #pragma to raise a custom warning within the VS IDE? I'd need it for a while because there are two classes in this code that contain the very same data but derive from very different classes (Attribute, EventArgs). So if one modified the former class without modifying the latter, the whole system would stop working.

As long as there is no solution, I'd like to raise this custom warning so that everybody trying to start a new build must agree on that they recognized the code smell.

This sounds like a case for code generation, an interface or shared class — Daniel A. White, Jan 08 '23 at 17:16

@DanielA.White I don't like interfaces, because they cause more trouble than relief. Plus they trigger yet more copy & paste. — CarstenP, Jan 08 '23 at 17:45
@CarstenP As Gian Paolo said, `#warning` should help your needs. If it solves your problem, you should mark it as answer, it will help others with the same problem. — Jiale Xue - MSFT, Jan 09 '23 at 08:27

It seems you are looking #warning directive

#warning careful with this method, if modified you have to modify this and that.
