This is what works for me:

    ScriptRuntime runtime = ScriptRuntime.Create();
    ScriptEngine engine = runtime.GetEngine("py");

    // These next two lines are needed if you expect to be able to import System
    // without manually loading the assembly through Python
    // runtime.LoadAssembly(typeof(string).Assembly);
    // runtime.LoadAssembly(typeof(System.Diagnostics.Debug).Assembly);

    // File foo.py contains class Foo
    ScriptScope scope = runtime.ExecuteFile("foo.py");
    object theClass;
    scope.TryGetVariable("Foo", out theClass);
    object theValue = PythonCalls.Call(theClass);
