I have Intel® Parallel Studio XE, which offer a Fortran compiler for Microsoft Visual Studio (I use the 2013 Ultimate version). It is possible to execute a Fortran file in a C# application or it must be a C/C++ application? How can I do it?
None of them can use fortran, you must create a fortran project, you can't mix languages. A possible solution is to create a DLL and interface it with DLLImport, this may help you:
