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
Message="Type 'IronPython.Runtime.PythonContext' doesn't provide a
suitable public constructor or its implementation is faulty."
Source="Microsoft.Scripting"
StackTrace:

actualType, Object[] args)

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.
