Python int type is translated to pyInt when passed as a .net Dictionary value only in 3.x version

Environment

Pythonnet version: 3.0.0a2
Python version: 3.7, 3.8, 3.9, 3.10
Operating System: Windows
.NET Runtime: 4.7.2 framework

Details

After upgrading to pre release 3.0.0a2 version, the python int type is getting translated to PyInt instead of System.int32 inside the .NET DLL, and hence getting a unable to cast exception. this is working fine in 2.x version.

DLL method:

public void DictMethod(Dictionary<string, object> paramDict)
  {
            Console.WriteLine("Inside");
            Console.WriteLine(paramDict["index"].GetType().ToString());
            var index = Convert.ToInt32((paramDict["index"]));
            
        }

Python script:

   clr.AddReference("System.Collections")
from System.Collections.Generic import Dictionary
from System import String
from System import Object
clr.AddReference("PyTest")
from PyTest import PyClass

class Utils(object):

    @staticmethod
    def prepare_dict(**kwargs):

        dict_net = Dictionary[String,Object]()
        for key_value in kwargs.keys():
            dict_net.Add(key_value,kwargs[key_value])
        return dict_net

parameters = {}
parameters['index'] = 1
net_dict = Utils.prepare_dict(**parameters)
obj = PyClass()
obj.DictMethod(net_dict)

Output in 3.x version:
