how to get dependency of my C# dll in ctypes library python?

Question

I want to run C# dll with .net framework 4.7 in python app. I use dllExport nuget for my method in dll because ctypes with this way access my method. Sample:

using System.Runtime.InteropServices;

namespace MyNameSpace
{
    public class MyClass
    {
        [DllExport("MyMethod", CallingConvention = CallingConvention.StdCall)]
        public static int MyMethod(int a,int b)
        {
            return a + b;
        }
    }
}

In python:

def myFunction():
  Dllpath = os.path.join("dll folder directory")
  os.add_dll_directory(Dllpath + r"myDll.dll")
  # WinDll used just windows os, in Linux is different
  lib = WinDLL(Dllpath + r"myDll.dll")
  lib.MyMethod(12,17)

it is work.

but when I use other library (dll) in my dll I get this Error:

[WinError -532462766] Windows Error 0xe0434352

I guess this error was for problem in dependency of my dll.

how to resolve this error?
