Does Python.Net 3.0 support self-contained .NET?
I'm able to successfully call from Python to .NET when publishing my dll as framework dependent however when I publish the same dll as self-contained I get:
I n i t i a l i z a t i o n f o r s e l f - c o n t a i n e d c o m p o n e n t s i s n o t s u p p o r t e d

My Python code:

import sys
from clr_loader import get_coreclr
from pythonnet import set_runtime
dot_net_path = os.path.join(os.path.dirname(os.path.abspath(__file__)), r'MyDll\publish')
rt = get_coreclr(os.path.join(dot_net_path, 'MyApp.runtimeconfig.json'))
set_runtime(rt)
import clr
sys.path.append(dot_net_path)
result = clr.FindAssembly("MyApp")
print('FindAssembly returned:', result)
result = clr.AddReference("MyApp")
print('AddReference returned:', result)
from MyApp import MyClass
my = MyClass()
result = my.PrintToConsole('Hello from Python')
print('Python finished')My .NET code:
using System;
namespace MyApp
{
public class MyClass
{
public int PrintToConsole(string message)
{
Console.WriteLine("C# .NET Core DLL says : " + message);
return 123;
}
}
