I want to configure a social viewer based app to show ads only if the app has not been purchased and not to alter the functionality or usability of the app in any other way.

Would this be the proper way to achieve this in Configuration.xaml?

<Config:ReaderConfiguration x:Key="Configuration"                           

FeedbackEmailAddress="me@mail.com"                           

FullFunctionalityInTrialMode="False"                 //Do not want to enable Full functionality          

FullFunctionalityTrialModeLengthInDays="0"                       //Do not want to enable full functionality ever    

TrialModeLengthInDays="9999"                           //Would like the app to display advertisement indefinitely unless purchased

TestMode="Disabled"                           

LinkShortener="BitLy">

Thank you for any input on this, I am having difficulty affirming this in my testing efforts.

@Nick,

Thanks for the confirmatiion.  I wanted to make sure I wasn't missing anything.  

For what it's worth to anyone else I also went and commented out the 4 or so instances of "you have x days left until trial expires".

The abiility to test in different test modes is clutch.

Oh very cool, I like that.

So if I....
                                FullFunctionalityInTrialMode="True"
                                FullFunctionalityTrialModeLengthInDays="5"
                                TrialModeLengthInDays="9999"
                                TestMode="Disabled"

Then after 5 fully functional days it'll go into "Limited" mode and after 9994 days it'll go into "Trial" mode?
