I would like to specify the .Net version explicitly. My requirement is: .Net Framework SDK 4.8

How can I find out which runtime is being used?

And how can I specify it explicitly?

Running this code

pythonnet.load()
pythonnet.get_runtime_info()

generated this output:

  Version:      <undefined>
  Initialized:  True
  Shut down:    False
  Properties:
    domain = 
    config_file = None

Why is the Version undefined.

My Requirements are .Net Framework SDK 4.8

When i load this runtimeconfig.json

{
    "runtimeOptions": {
      "tfm": "net4.8",
      "frameworks": [       
        {
          "name": "Microsoft.NETCore.App",
          "version": "4.8"
        }
      ]
    }
  }

import logging
import os

import pythonnet

ROOT = os.path.abspath(os.path.dirname(__file__))
logger = logging.getLogger(__name__)

def initialize():
    pythonnet.load(
        "netfx",
        config_file=os.path.join(ROOT, "runtimeconfig.json"),
    )
    logger.info("------------>: %s", pythonnet.get_runtime_info())

Output
