Visual Studio 2019 C++ not resolving custom types in source file

Question

Hello,

I'm using VS 2019,

I upgraded a vc++ project in this vs edition.

In the source file, a lot of types are marked red.
the identifer types are defined in an external .h file.

the include path is correctly set in project settings though.
and the project builds well.

So how do i fix source include path for the editor to resolve types?

When your right-click on the filename in the #include and select Open Document "..." is the file shown in VS? If not then VS cannot find it. If it does open then the compiler probably can find it too.
