Some of those look like names from A9, which have changed in B1. The easiest way to evaluate an expression from scratch seems to be as follows:
ScriptEngine engine = ScriptRuntime.Create().GetEngine("py"); ScriptScope scope = engine.CreateScope(); ScriptSource source = engine.CreateScriptSourceFromString("1 + 1", SourceCodeKind.Expression); int result = source.Execute<int>(scope); On Sat, Mar 29, 2008 at 10:00 AM, Michael Foord <[EMAIL PROTECTED]> wrote: > Hello guys, > > I'm trying to do some simple examples of hosting with IronPython 2.
