I use Intel compiler fortran with VS for 15 years now . 

But I have difficulties to use the the debugger with IFX version.

 I understand  i have to  install Intel® Fortran Expression Evaluator (FEE) extension manually 

Can you explain the procedure to install it? Thank you.

From Visual Studio select the "Extensions" menu, then "Manage Extensions" => type "intel fortran expression evaluator" to search for the extension and install it.

 

There is an interesting discussion here about the FEE:

Thank you, it is done.

 

Nethertheless, I have still troubles for the allocated tables  .

 In the specification of the intel Fortran Expression it is written: 

"The Intel® Fortran Expression Evaluator allows developers to:

  • Evaluate Fortran expressions during debugging. (ok for me)
  • Check the values of variables or compute custom expressions on-the-fly. (ok for me, it must be in UPPER CASE , ok)
  • Support array slicing, derived types, and some Fortran intrinsic functions (e.g. ALLOCATED, ASSOCIATED, LOC) ." (not ok for me).

Maybe i have forgotten something or there is a restriction , or  i need probably to install something else?

A simple example below: impossible to read the value Tab_XY

It works for me even in lower case (although tab_xy is displayed in upper case in the Watch window).

 

I'm using Visual Studio Community 2022 version 17.14.20 and ifx 2025.3.0

Seeing your results, as it didn't work on my own pc, so i tried on a new pc with nothing  installed on it and effectively it works now. 

Thus I decided  to desintall the Intel products on my pc (it was not sufficient)  and to desintall  either Visual Studio 2022 completely.

I reinstall everything: 

Visual Studio Community 2022 version 17.14.20

and

compiler ifx  2025.3.1.15

and

The Intel® Fortran Expression Evaluator 2025.2.2

and now it works 

I think there was  probably a conflict with a previous version not completely deleted.

Anyway, thank you for your help.

Good to know!

Yes, upgrading to the last versions of VS and IFX is generally the good option.
