@Doug thanks for the snippet but the point its a bit off i think?

My post was to show a pure Python module written in CPython totally for CPython objects was usable in IronPython and could work on C# objects, with no modifications.

Pinsor dynamically loads classes and their dependencies on the fly, calling the constructors of objects as needed. Very easy and simple to do in python and a bit of a pain in C# (.net reflection API is unfun to use).

In summary, I can use Pythonic ways of solving problems on .Net code.

Here in PowerShell, it compiles the C# on the fly, then runs it.

$code = @”
using System;
public class Command
{
private readonly DoingStuff _stuff;

public Command (DoingStuff stuff)
{
_stuff = stuff;
}
public void Execute()
{
Console.WriteLine(_stuff.Message);
}
}
public class DoingStuff
{
public string Message
{
get { return “From the Doing Stuff Class, I’m doing stuff”; }
}
}
“@

Add-Type $code

(New-Object Command( New-Object DoingStuff )).Execute()

@JP that’s gorgeous. I think with that sort of forwards/reverse interop we’ll start seeing more components build for .Net. Something that are painful in one language will be easy in another.

Downside is if we end up with awful api’s for a majority of languages (like VB.net and lambda heavy libraries).

You could do the reverse in about 2 lines of C# 4.0 code. That is, import pinsor.py (just assuming that is what it’s called) into .NET and make calls on it. If memory serves me correctly, something like this:

ScriptRuntime py = Python.CreateRuntime();
dynamic pinsor = py.UseFile(“pinsor.py”);

Haven’t tried it, but this seems pretty compelling.
