passing Lists from IronPython to C#

I want to pass a list of strings from IronPython 2.6 for .NET 2.0 to a C# program (I'm using .NET 2.0 because I'm working with an api that runs off of DLLs built on 2.0). But I'm not sure how to cast it as it comes back from the ScriptEngine.

namespace test1
{
    class Program
    {
        static void Main(string[] args)
        {
            ScriptEngine engine = Python.CreateEngine();
            ScriptSource source = engine.CreateScriptSourceFromFile("C:\\File\\Path\\To\\my\\script.py");
            ScriptScope scope = engine.CreateScope();

            ObjectOperations op = engine.Operations;

            source.Execute(scope); // class object created
            object classObject = scope.GetVariable("MyClass"); // get the class object
            object instance = op.Invoke(classObject); // create the instance
            object method = op.GetMember(instance, "myMethod"); // get a method
            List<string> result = (List<string>)op.Invoke(method); // call the method and get result
            Console.WriteLine(result.ToString());
            Console.Read();
        }
    }
}

my python code has a class with a method that returns a python list of strings:

class MyClass(object):
    def myMethod(self):
        return ['a','list','of','strings']

I get this error:

Unable to cast object of type 'IronPython.Runtime.List' to type 'System.Collections.Generic.List`1[System.String]'.
