future feature is not defined

Prerequisites

[ ] Are you running the latest version? - 3.4.1
[ ] Are you reporting to the correct repository? - yes.
[ ] Did you perform a cursory search? - yes. I found out that this issue appears because "the import of future annotations is available starting with Python 3.7." And, since IronPython runs on 3.4 it's not working...I guess?

Description

I have a python script wirtten on Python 3.9. When I try to run it in my application I get this

Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1] An unhandled exception has occurred while executing the request.

Steps to Reproduce

Create a Python 3.9 script with "from future import annotations"
Try to run it via .NET environment.

Expected behavior: I simpy expect all the libraries to be imported correctly.

Actual behavior: I got this error I've described.
