[IronPython] Access to CLR System namespace when python is executed inside C#

What's likely happening is that you're getting a different ScriptEnvironment than the one which "normal" script code is running under.  You could get the current runtime by:


And then use that because it'll already have System.dll loaded.  Alternately you can add the references yourself:

ScriptEnvironment.GetEnvironment().LoadAssembly(typeof(string).Assembly);    // mscorlib
ScriptEnvironment.GetEnvironment().LoadAssembly(typeof(System.Diagnostics.Debug).Assembly); // System.dll

Subject: [IronPython] Access to CLR System namespace when python is executed inside C#

I am struggling to get IP to honor the System module when the IP is executed inside C#. I am using Silverlight 2.0 Beta 1. I have the following code.

import clr
import System", SourceCodeKind.File)); <-- I've also tried SourceCodeKind.Statements and SourceCodeKind.InteractiveCode

This code throws a "The method or operation is not implemented" exception. It seems that any reference to System or any of its classes throws the exception. I was hoping to have my custom assemblies executing in IP through C# by now, and I can't even get the CLR assemblies to execute. Please Help!
