XML Comments looks different, but simple comments should work too, however they need to be inserted into the .h files, such as graph_funcs.h.
Visual Studio Community 2022, not seeing some xml comments

I have multiple projects within one solution. I use the functions of multiple other projects within another project. When i hover above the function of different projects, there's no xml comments (like describing how a function works, its inputs and outputs). It still shows when I hover above functions of this project.
I want to know how to see xml comments when hovering over a function belonging to a different project in solution.

Make sure that the comments are inserted correctly to header files. Show an example that does not work.
