Re: [Py2exe-users] [python] Re: create dll from module?

[Michael F. <fuz...@vo...>]

Python.NET provides a managed wrapper around the CPython embedding API. 
This allows you to easily (relatively) embed CPython in a .NET application.

The wrapper is 'Python.Runtime.dll' and is dependent on having 
python24.dll (or whatever) available...

Remember that C (and thus DLL functions) have no overloading/duck typing.
