That was it. Curt to the rescue again. Thanks.
A possible suggestion would be a more descriptive error message :)

Hi
Was there ever a solution to this problem? I'm getting the same
thing, though not with NUnit. To port my IP interface from 1.1 to
2.0 (beta 1), I created a separate test application, which worked
fine. However I'm merging the code into my "real" application, but
I'm not able to create a ScriptEngine.
_runtime = ScriptRuntime.Create();
string[] languages =
_runtime.GetRegisteredLanguageIdentifiers(); // finds 18
languages, including "py"
_engine = _runtime.GetEngine("py"); // <--- throws an exception
Microsoft.Scripting.Runtime.InvalidImplementationException was
unhandled

Not sure if it's important, but the application uses a few
assemblies, and the IP wrapper classes are in a separate assembly
to where they are used.
Thanks, Paul

There's an inner exception here (probably from Importer.cs in
MakeImportSite) but there isn't much info on it. Could you run it under a
debugger and get that original stack trace? It's not clear to me why we would
blow up there.
Thanks for your help.
Sorry for some text in Portuguese below. I hope it doesn't get in the way.
The exception occurs within class ReflectionUtils, method CreateInstance<T>.
Line 127 is:
return (T)Activator.CreateInstance(actualType, args);
This in turns ends up calling the constructor public
PythonContext(ScriptDomainManager/*!*/ manager) in class
PythonContext.
Line 120 is:
_importer = new Importer(this);
A step into this line will cause the exception.
The stack trace of the innermost exception
