Could you please describe a problem you have with fsi.exe from VisualStudio?


Kind regards,




Hi Sofya, thank you for your reply. Our team is evaluating rider as it has better F# support and interactive is critical component of dev cycle. It would be nice to have ability to point Rider a specific build of fsi and core library.

Please let me know if you need more details.

Thank you!


Denskh, the option to choose another F# Interactive is available in upcoming EAP 8.
