WP7 NavigationService.Navigate pass a pointer without using global variables?

I am navigating to page X in WP7. I have an object (let's call it banana) in my ViewModel, which is where the NavigationService.Navigate call is being made. Page X needs a reference to the banana. How can I do that?

The answer to this question recommends using the global App class. Not a good option for me because I might have multiple instances of the class of page X, and I wouldn't want to confuse other instances if they are later navigated to.

I would also prefer not to have to serialize the banana.

You can either use the query string (to send the id, for example) as suggested by @Matt, and you could also send the object itself via a message for example, you can use the Messenger class from MVVM Light for that.

Hope this helps :)

If there could be multiple instances of the page then you'll need to pass any parameters it needs as part of the querystring in the Uri you use for navigation.
