Has anyone had problems with the current Visual Studio (VS) Pro 2019 not recognizing the Parallel Studio XE Composer? This happened very recently. VS now tells me all my Fortran projects are incompatible, and no longer provides Fortran templates. I have a monthly subscription for VS that is up-to-date, and have been using it for over a year with no issues.
Right click on the solution name and reload the project, this is sometimes required, otherwise reinstall -- I would try the VS 2019 Preview Community if that does not work.
