OK, I see all that now in the Dev guide and in the sample application. I also noted that when I turned on security in the sample application it works OK. Can you post the stack trace from the exception? Maybe there is more of a clue in that. I can try in a bit to add security like this in an application to see if I duplicate it. Also, are you using the Localization? If not, is localization turned off in the app.config? Just checking to verify which line of code is running in your code above.
