So don't use precompiled headers for that single file!

Being a .cpp file, it will have separate compilation options anyway.

You might be able to create two precompiled headers in your project. There's a property on each source file that determines if it's going to use a precompiled header, or generate a precompiled header - try setting two different sources to generate a header.

I've made tiny edits - they are not direct quotes. The reason for my change is you may want to exclude a C or a C++ file from using precompiled headers for a particular case. Bo assumes C++ as it's a direct answer to the question. Zuuum assumes C, and that's the case for me and in my illustration. It could be either in practice.

It's understandable but annoying that the location of options in menus changes from one release of visual studio to another, but here is the location of the menu item in my current visual studio (2019).
