In past versions of Visual Studio (sorry, I can't recall which) it was possible to have a .F file open, then right-click an INCLUDEd file and be given the option to open the include file, assuming it could be located. I found an old thread that refers to this, but I doesn't work in VS 2010 SLN files that I have built by hand; nor in those built by Cmake. This occurs even if the INCLUDE file (.F77 suffix) is explicitly put in a "Header Files" section. The Error dialog reports "Object reference not set to an instance of an object." The include path is valid and the projects build and run normally. In this mixed-language solution, the include (.h) files associated with the C-language portions all work correctly.
Using my current version (VS10.0.40219 SP1Rel) I was unable to find a way to add this through any Tools>Options>Text Editor>Fortran or Tools>Options>Intel Visual Fortran options.
Is this a feature I should be able to make work?
