Re: [Python.NET] Embedding a Python interactive shell in a .NET application

Hey,

a while ago I wrote something like a light wrapper around Python.NET to
embed CPython with numpy/scipy in a .NET GUI. It manages local/global
dictionaries, automatically converts simple data types and numpy
arrrays<->C# arrays and provides a plotting widget in C# that shows
matplotlib plots. It also has some other convenience functions.

The code is by no means complete, fully tested or even nice. However, for
me it works.

I uploaded it to github: https://github.com/Lodomir/PythonInterface
As it demonstrates some not-well documented use of Python.NET, I thought it
maybe nice to share the code.

You will need to add the references to Python.NET to build the main project
(PythonInterface) and additionally to the PythonInterface-DLL to build the
examples.

Cheers
Nils
