[IronPython] IronPython 2.0 Alpha 2

[Michael Foord]

Hello all,

I've been playing with a simple C# script illustrating embedding 
IronPython 2.0.

The following code works fine for 2.0 Alpha 1:

using System;
using Microsoft.Scripting;

namespace IronPythonScriptHost
{
    class Program
    {
        static void Main(string[] args)
        {
            string code = "print \"Hello\" + Name";
            Script.SetVariable("Name", "Nick");
            Script.Execute("py", code);
            Console.Read(); 
        }
    }
}


When run with 2.0 Alpha 2, it produces the following error (saying that 
the version of the Python language provider is incorrect):

Unhandled Exception: Microsoft.Scripting.MissingTypeException: Type 
'IronPython, Version=2.0.0.100, Culture=neutral,

As far as I can see from the docs, this part of the API should still 
work, and I am referencing the DLLs provided in the Alpha 2 release. Any 
clues?
