It's no fun to debug a problem when .NET, the C python library and
python code meet each other. It's a constant task switch between a C#
debugger, gdb and Python. You don't want to debug it when threads join
the battle. It may take hours before you even grasp which part of your
code is causing trouble.
I wish I could exercise more patience and spare more time on the debug
support. Unfortunately Python's Py_DEBUG / Py_TRACE_REFS changes the
memory layout and API calls a lot. It would be much easier to debug
reference leaks and other problems with a debug build of Python.
I think the use case of PythonDotNet is different from IronPython's use
case. PythonDotNet doesn't aim to be another Python implementation or a
replacement for IronPython. I usually explain it as a bridge between
managed code/.NET/C# on the one side and CPython and C extensions on the
You should use IronPython if you want to do Python development under
.NET. PythonDotNet is for people who need to embed Python C extensions
in managed code or embed managed code in applications with a CPython
For example I'm experimenting with using and script a C# assembly with
Python inside Blender. So far I haven't done much but the initial
experiments are doing well.
